Subject: [PATCH 05/40] fix(json): keep grids, schedule tasks and element
 properties on import

Getter-only collections (element properties and mesh indices, grid lines, TimeLiner tasks, attached element ids and child tasks) were skipped by JsonViewerImporter; they are now populated, as ClashTest.Clashes already was.

Subject: [PATCH 06/40] feat(viewer): three.js viewer scaffold with batched
 rendering

The viewer is built from ES modules under src/IOViewer/Viewer/src with esbuild into dist/viewer.js (three.js bundled, committed so the .NET build needs no Node). ModelScene draws one BatchedMesh per material with per-element visibility and highlight colour; empty documents show a 'no geometry' message. The exporter escapes closing script/style tags in the inlined code. Adds node unit tests, Playwright smoke tests and synthetic building/empty fixtures exported through the CLI.

Subject: [PATCH 08/40] fix(viewer): correct shading of mirrored instances

BatchedMesh cannot flip the front face per instance, so with DoubleSide an instance with a negative determinant showed its outer faces as back faces and lit them with inward normals. Such instances now draw a reversed-winding copy of their geometry, added once per geometry and bucket. The fixture gains a column and its mirrored twin; an e2e test compares their lit faces and unit tests cover the determinant check and the winding copy.

Subject: [PATCH 12/40] feat(viewer): floating panels, grouped toolbar, context
 menu

Left icon rail with one floating panel at a time (model tree, views, clashes,
4D, links; data panels only when the document has data), grouped bottom toolbar,
virtualized model tree with search, right-click menu, H/I/Shift+H/F hotkeys,
status bar and truncation banner. Adds the escaping fixture and a generated
20 000-element model for the tree virtualization test.

Subject: [PATCH 13/40] fix(viewer): keep context menu open on panel scroll,
 tidy menu and toolbar behaviour

Scrolling inside the UI panels no longer closes the menu, so revealing the
right-clicked element in the tree keeps it open. A press outside the menu only
dismisses it. Esc closes an open menu without touching the selection. Refused
fullscreen and failed Id copies show a message instead of being swallowed.
The settings button is removed.

Subject: [PATCH 22/40] test(viewer): synthetic large-model generator and
 performance harness

tools/SyntheticModel writes a seeded pipe network (20 shared geometries,
~100 triangles per element, --unique for per-mesh geometry) as an exported
page; npm run perf (headed Playwright, outside npm run e2e) measures load,
orbit fps, pick, selection, hide/isolate/show all, tree search, display
modes and 4D steps, and writes JSON results.

Subject: [PATCH 23/40] perf(viewer): meet 200k element interaction targets

- Draw lists: each bucket fills its multi-draw list in one loop over typed
  arrays (visibility, frustum test on precomputed bounding spheres) in place
  of three's per-instance objects; transparent buckets sort back to front
  with one numeric sort; no whole-mesh bounds walk at first render.
- Motion detail: frames are drawn within a cost budget (draws and
  triangles), leaving out what is smallest on screen, and the full model is
  drawn 200 ms after the last change; the budget adapts to the frame rate
  seen while the camera moves, so fast GPUs keep full detail.
- BIN is read from its text node in pieces (a block over the JS string
  limit loaded as empty, so models of ~380 MB binary could not open),
  decoded with Uint8Array.setFromBase64 where available, and released
  once the scene holds its copies.
- Box select projects element boxes without allocations and builds the
  section planes once; the picker fills its id textures without a view
  per instance.

Integrated Radeon, 200 000 elements / 19.2 M triangles: orbit 15 -> 30 fps,
pick 6.5 -> 1.5 ms, hide/isolate/show all on screen in < 50 ms, open 0.6 s
(3.9 s with unshared geometry, which did not open before).

Subject: [PATCH 24/40] fix(viewer): robust adaptive detail and honest
 full-frame timings

- Frames without camera motion (click, hide, isolate, show all, 4D step)
  always draw the full model; near/far changes from what is shown do not
  count as motion. Only frames where the camera moved leave detail out.
- The budget adapts on the cost of frames drawn while moving: the wait
  between the request and the animation frame plus the frame's script
  time, never the idle time between input events.
- The budget has a floor and the largest objects in view are always
  drawn; it grows only while detail is being left out and never past
  the cost of what is in view.
- The perf harness records per orbit frame the share of the instances in
  view that was drawn and the detail threshold, marks whether an
  operation's timed frame was full, and defaults to the OS temp folder
  (as does the generator's output).

Subject: [PATCH 25/40] test(viewer): timing ladder and full-detail metrics in
 the perf harness

PERF_LADDER generates and measures synthetic pages of several sizes and prints one table across them
(plus JSON); every run records a full-detail still frame, its draw calls, a full-detail orbit and
scene.memory() when the engine has it. PERF_VARIANTS adds rendering-only runs with a section box,
textures (generator option --textured) or IOVIEWER_TEST.noHideBranch.

Subject: [PATCH 26/40] feat(export): format 3 with grid-quantized positions
 and octahedral normals

Geometry positions are written as u16 steps of 2^-10 m from a grid-aligned origin (META q = {o, s}) when
they span at most 65535 steps, else as f32 as before; normals as octahedral snorm16 pairs (new view type
i16). Meshes with their own vertices are placed at their snapped minimum corner, so vertices that coincide
in the world decode to the same grid point in every mesh. The viewer decodes both encodings and still reads
format 2. The C# public API is unchanged.

Subject: [PATCH 27/40] fix(export): keep deduplicating off-grid translated
 copies in format 3

A mesh with its own vertices that is a translated copy of an earlier one (equal float32 positions
relative to the exact minimum corner, indices, normals and UVs, as format 2 compared them) reuses
that geometry with an exact, unsnapped translation. Only the first occurrence stays on the global
grid. The perf harness now regenerates ladder pages when the library, viewer or generator sources
change, not only the viewer bundle.

Subject: [PATCH 28/40] fix(export): keep scaled shared geometry in f32 and pin
 f32 placement

A shared geometry that any instance scales up (an axis longer than 1 + 1e-6) is written as f32: its
grid steps are in local units, so the scale would multiply the 0.49 mm bound. New tests decode the
placement of f32 geometry (georeferenced own mesh, its off-grid twin, translated shared geometry)
and of scaled and unscaled shared instances.

Subject: [PATCH 29/40] perf(viewer): merged spatial chunks with a slot-state
 texture

Per material, instances are split into chunks of up to 32768 vertices of
nearby instances (k-d split by vertex weight), baked once into world space
(u16 grid steps or f32 for elements over ~64 m, octahedral normals, verbatim
copy for translation-only format-3 instances) and drawn with one call each.
Every instance owns a slot; its colour and shown flag live in an sRGB slot
texture, so select, hide, isolate and 4D steps rewrite texels only. Slots in a
chunk are ordered by size: a frame draws the span from the first to the last
shown slot, and motion detail cuts that span as a prefix.

Picking renders slot + interpolated surface point into a float target, with
an RGBA8 slot + packed-depth fallback. The octahedral normal travels in the
`normal` attribute: without one three shades Lambert flat. A lost WebGL
context now shows a reload message (GPU buffers keep no CPU copy).

Subject: [PATCH 30/40] fix(viewer): u32 index boundary, lazy normal decode,
 robust load and context handling

- A chunk of exactly 65536 vertices used a u16 index whose value 0xFFFF is
  WebGL2's primitive restart, dropping every triangle and line through its
  last vertex: u32 from 65536 vertices, one rule for triangles and lines.
- Unit normals are decoded from the octahedral pairs only for transformed
  slots and released with their geometry's last chunk; translation-only
  slots copy the pairs (200k own-geometry model: -270 MB renderer peak).
- After a lost context, also when the browser restores it, nothing renders
  or picks any more (the buffers keep no CPU copy); the message stays.
- A model over the slot limit opens without geometry with a message.
- Instances with a non-finite box get no slot and stay out of the bounds;
  non-finite centres no longer lose or double instances in the split.

 ## [Unreleased]
 
 ### Fixed
+- `JsonViewerImporter` keeps grid lines, 4D tasks with their attached element ids and child tasks, clash results,
+  element properties and element mesh indices; they were silently dropped on load.
 - The `IOViewer` package now includes the XML documentation file, so existing API comments show in IntelliSense.
 - The release workflow runs only for version tags again, fails on any `gh release` error and no longer overwrites assets of an existing release.
 - `tools/pack-release.ps1` fails when creating the source archive fails.
@@ -14,14 +16,64 @@ API between minor releases.
 - The logo on the documentation site no longer covers half of the page; it is sized to the navigation bar.
 
 ### Added
+- A new HTML viewer built on three.js 0.186.1, embedded in the page, which still works offline without network requests:
+  - floating panels (model tree with search, properties, views, sections, clashes, 4D, linked files), a toolbar with
+    labelled groups, a status bar with selected and total counts, and a context menu;
+  - Navisworks-style mouse: orbit around the point under the cursor, pan with the middle or right button, zoom to the
+    cursor, Ctrl+click, window (left to right) and crossing (right to left) box selection; hotkeys H, I, Shift+H, F, Esc;
+  - a view cube drawn from the camera orientation, with face clicks, 90° arrows and a home button;
+  - up to six section planes moved and rotated with an in-scene gizmo, or a section box that keeps or cuts its inside,
+    with face handles, a centre handle and a box around the selection;
+  - distance measurement, display modes (materials, textures, white, wireframe), grid lines, global opacity,
+    perspective or orthographic camera and fullscreen;
+  - saved viewpoints with a tour, a clash list that flies to the clash and selects both elements, a 4D schedule player
+    and linked-file visibility;
+  - Russian or English interface, chosen from the browser language;
+  - a message instead of a blank page when the graphics context is lost or the model has more objects than the GPU
+    can address.
+- Shared geometry: `ViewerDocument.Geometries`, `ViewerGeometry`, `ViewerMesh.GeometryId`, `ViewerMesh.Transform` and
+  the `Transform3d` affine transform. The HTML exporter writes each shared geometry once and also writes meshes that
+  are exact translated copies of each other once.
+- `ViewerClashResult.Element1Id` and `Element2Id`. The viewer selects clashing elements by Id, and by name only when the
+  name is unique.
+- The HTML exporter writes the projection of saved viewpoints, so orthographic viewpoints open orthographic.
+- `THIRD-PARTY-NOTICES.md` with the three.js license, included in the NuGet packages and the release archives.
+- A CI job for the viewer: it rebuilds the bundle, checks that the committed `dist/viewer.js` matches the sources and
+  runs the unit and Playwright end-to-end tests. Dependabot also updates the viewer's npm packages.
 - Links to the DeepWiki overview of the repository in the README and on the documentation site.
 
 ### Changed
+- `GlbViewerImporter` keeps node transforms and shared meshes (one `ViewerGeometry` per mesh primitive, one
+  `ViewerMesh` per node that uses it) and converts glTF's Y-up to the viewer's Z-up, so GLB models no longer lie on
+  their side. A node hierarchy that is not a tree (a node referenced twice, or a cycle) now throws
+  `InvalidDataException`.
+- `HtmlViewerOptions.MaxMeshVertices` defaults to no limit (was 5,000,000) and no longer cuts the model silently: when a
+  lower limit leaves meshes out, the viewer shows a banner with the number of meshes written.
+- The HTML payload uses format 3: one base64 binary block, positions quantized to 16-bit steps of 2⁻¹⁰ m (error at most
+  0.49 mm, 0.85 mm for rotated shared geometry) and octahedral 16-bit normals. Geometry larger than about 64 m, and
+  shared geometry that any instance scales up, stays 32-bit float. The page of a real 746 MB IFC water-supply model
+  shrank from 57.5 MB to 44.4 MB. The HTML is written to the output stream as it is produced.
+- The viewer merges geometry into spatial chunks per material and keeps per-object state (hidden, selected, tint) in a
+  texture, so hide, isolate, selection and 4D colouring never rebuild geometry. When merged data would exceed
+  384 MiB, repeated shapes are drawn as instanced copies in spatially bounded cells instead.
+- Measured on an integrated 2-CU AMD GPU: a model of 200,000 elements and 19.2 million triangles opens in about 1.3 s,
+  orbits at 30 fps at full detail (60 fps on an RTX 4080), draws a full frame in 30.3 ms and shows a click, hide or
+  show all in about 52 ms, using about 327 MB of GPU memory. A model of 1,000,000 elements opens in about 2.2 s, draws
+  a full frame in 0.21 s and uses about 88 MB of GPU memory; it orbits at 20 fps (95th percentile), picking an object
+  takes about 22 ms and a still frame costs about 23 ms of CPU time.
+- Transparent objects are sorted back to front per chunk or cell, not per object.
+- Package descriptions and documentation say "no external dependencies, works offline" instead of "zero-dependency".
 - Tests run on both .NET 8 and .NET 10.
 - `global.json`, CI workflows and repository settings follow the shared IOExtend conventions: SDK 10.0.100 without prerelease, NuGet vulnerability audit, Dependabot, LF line endings, issue and pull request templates.
 - Copyright holder is `mahach666` in the license, package metadata and README.
 - README and documentation state that IOViewer is not affiliated with Autodesk.
 - `SECURITY.md` and `CONTRIBUTING.md` describe supported versions, security scope, development setup and the clean-room policy.
+- `CONTRIBUTING.md` describes the viewer toolchain (Node.js 24, `npm ci`, `npm run build`, `npm test`, `npm run e2e`,
+  manual `npm run perf`).
+
+### Removed
+- The turntable (automatic 360° rotation) of the old viewer.
+- The previous hand-written WebGL viewer template, replaced by the three.js viewer.

 The repository ships no customer models.
 
+### Viewer
+
+The HTML viewer is a JavaScript project in `src/IOViewer/Viewer` (three.js,
+bundled with esbuild). Its built script `dist/viewer.js` is committed and
+embedded in the library, so .NET work does not need Node.js. To change the
+viewer, install Node.js 24 and run from `src/IOViewer/Viewer`:
+
+```sh
+npm ci            # exact versions from package-lock.json
+npm run build     # rebuilds dist/viewer.js
+npm test          # unit tests (node --test)
+npm run e2e       # builds, exports the fixtures with the CLI and runs Playwright (Chromium)
+```
+
+Commit `dist/viewer.js` together with the source change: CI rebuilds it and
+fails when it differs from the committed file. The end-to-end tests need the
+.NET SDK and a Chromium for Playwright (`npx playwright install chromium`).
+Fixtures are in `tests/fixtures/viewer`.
+
+`npm run perf` runs the manual performance harness in a visible Chromium
+window (for example `PERF_LADDER=25000,200000` measures synthetic models made
+by `tools/SyntheticModel`); its settings are described at the top of
+`test/perf/orbit.perf.js`. It is not part of CI; include its numbers in the
+pull request when a change can affect rendering speed. npm dependencies are
+pinned to exact versions.
+
 ## Clean-room policy
 
 - Write all code independently. Do not use decompiled or leaked source code,
   proprietary headers, vendor SDKs or code copied from other viewers.
-- Do not add third-party JavaScript to the generated HTML. The viewer runs on
-  plain WebGL and must stay self-contained and offline.
+- The only third-party JavaScript in the generated HTML is three.js (MIT),
+  listed in `THIRD-PARTY-NOTICES.md`. Discuss any other runtime dependency
+  first and add its license there. The page must stay self-contained and
+  work offline: no CDN, web fonts or network requests.
 - Do not add customer models, confidential data, vendor files or binaries to
   the repository. Keep private test files outside version control.
 - Do not put personal data in code, documentation, test data or commit

-The generated HTML file is completely self-contained, offline-ready, and works in any modern browser without external servers or cloud dependencies.
+The generated HTML is a single file with no external dependencies that works offline: it opens from disk (`file://`) in a current browser with WebGL 2 and makes no network requests. The viewer is built on [three.js](https://threejs.org/), which is embedded in the file (see [THIRD-PARTY-NOTICES.md](THIRD-PARTY-NOTICES.md)).
 
 Built clean-room under the [IOExtend](https://github.com/IOExtend) organization.
 
 ## What it does
 
-- Generates standalone, zero-dependency single-file interactive 3D WebGL HTML viewers (`.html`).
-- Packs binary geometry into Base64 little-endian `Float32Array` positions and `Uint32Array`/`Uint16Array` indices for ~3x smaller payload than JSON.
-- Shifts model coordinates Relative-To-Center (RTC) to eliminate WebGL 32-bit floating point precision jitter on large georeferenced coordinates.
-- Features an interactive 3D **ViewCube** with orientation faces and directional navigation arrows for instant orthographic alignment.
-- Provides comprehensive sectioning: arbitrary cutting planes with in-scene 3D normal gizmo manipulators, plus 6-sided Section Box volumes with fit-to-selection.
-- Supports multiple display modes: Material colors & opacity, Diffuse Textures with real-world UV box projection, White/Clay architectural model, Wireframe, and global scene opacity.
-- Manages BIM hierarchies with Category trees, element counters, linked files, instant search, and instance/type property inspection.
-- Includes coordination tools: 3D spatial grids projection, interactive 3D point-to-point measurement, 4D TimeLiner schedule simulation player, and clash detection inspection.
-- Drives smooth camera animations: cubic Ease-In-Out transitions, 360° Turntable presentation orbit, and Saved Viewpoints Walkthrough Tours.
-- Imports standard 3D formats out of the box: binary glTF 2.0 (`.glb`), Wavefront OBJ (`.obj`), and JSON snapshots.
+- Writes one self-contained HTML file per model; the viewer, its styles and the model data are all inlined.
+- Stores geometry once per shape: meshes can share a `ViewerGeometry` placed by a `Transform3d`, and the exporter also finds meshes that are exact translated copies of each other.
+- Packs geometry compactly: positions quantized to 16-bit steps of 2⁻¹⁰ m (error at most 0.49 mm, 0.85 mm for rotated shared geometry; geometry larger than about 64 m, or shared geometry that an instance scales up, stays 32-bit float), octahedral 16-bit normals, 16- or 32-bit indices, all in one base64 block.
+- Shifts coordinates relative to the model centre (RTC), so georeferenced models with coordinates around 10⁶ m do not jitter.
+- Draws large models with few draw calls: geometry is merged into spatial chunks per material (very large models draw their repeated shapes as instanced copies instead), and hiding, selection and colouring are per-object data, so they never rebuild geometry.
+- Viewer interface in Russian or English, chosen from the browser language:
+  - model tree by category with search, a properties panel and a selected/total counter;
+  - toolbar with labelled groups: navigation, sections, measure, display and view;
+  - context menu: properties, hide, isolate, show all, zoom to object, section box around the object, copy Id;
+  - view cube that follows the camera exactly, with face clicks, 90° arrows and a home button;
+  - section planes (up to six, moved and rotated with an in-scene gizmo) or a section box (keep inside or cut inside, face handles, move by the centre, box around the selection);
+  - point-to-point distance measurement, display modes (materials, textures, white, wireframe), grid lines and a global opacity slider;
+  - saved viewpoints with a viewpoint tour, clash results, a 4D schedule player and linked-file visibility, each shown only when the document has that data.
+- Imports binary glTF 2.0 (`.glb`), Wavefront OBJ (`.obj`), and JSON snapshots.

 - Version 0.1.0 is an initial release. The API can evolve before 1.0.
 - Standalone HTML export generates self-contained files with all geometry inlined. IOViewer does not simplify meshes, so models with millions of triangles produce large files; reduce them before export.
+- The binary geometry block is assembled in memory before it is written, so it must stay below 2 GB.
+- `HtmlViewerOptions.MaxMeshVertices` is unlimited by default. When a lower limit cuts the model, the viewer shows a banner with the number of meshes written.
+- The viewer needs WebGL 2. If the browser drops the graphics context, the page shows a message asking to reload it.
+- Transparent objects are sorted per chunk of merged geometry (or per cell of instanced copies), not per object, so overlapping transparent objects in the same chunk can blend in the wrong order.
+- Section planes and section boxes stored in `ViewerDocument` are kept in JSON snapshots but are not applied by the HTML viewer when it opens.

 ## Features
 
-- **Packed Binary Base64 Geometry**: Little-endian `Float32Array` positions and `Uint32Array`/`Uint16Array` indices encoded in base64, delivering ~3x smaller HTML payload and instant GPU buffer uploads.
-- **Relative-To-Center (RTC) Coordinates**: Model coordinates centered around $(0, 0, 0)$ with world offset, eliminating 32-bit WebGL floating point precision jitter on large georeferenced coordinates.
-- **3D ViewCube**: Interactive orientation cube with directional navigation arrows for instant orthographic alignment.
-- **Sectioning & Clipping**:
-  - Arbitrary section planes with interactive in-scene 3D normal gizmo manipulator.
-  - 6-sided Section Box volume with bounding wireframe, scaling slider, invert mode, and fit-to-selection.
-- **Display Modes**: Material colors with transparency, Diffuse Textures with real-world UV box projection, White/Clay architectural model, Wireframe, and global scene opacity slider.
-- **BIM Data Hierarchy & Navigation**: Category tree with element counts, Linked files panel, instant search with autocomplete and camera focus, properties inspector panel, and selection actions (Isolate, Hide, Show All).
-- **Coordination & Spatial Tools**: 3D spatial grids projection, interactive 3D point-to-point measurement, 4D TimeLiner schedule simulation player with status coloring, and clash detection inspection.
-- **Camera Animations**: Cubic Ease-In-Out transitions, Turntable 360° presentation orbit, and Saved Viewpoints Walkthrough Tour player.
+- **Compact geometry**: shared geometry stored once and placed by transforms; 16-bit quantized positions (error at most 0.49 mm), octahedral normals and 16- or 32-bit indices in one base64 block.
+- **Relative-To-Center (RTC) coordinates**: no precision jitter on georeferenced models.
+- **Large models**: geometry merged into spatial chunks per material with few draw calls; hiding, selection and colouring are per-object data, not geometry rebuilds.
+- **Navigation**: orbit around the point under the cursor, pan with the middle or right button, zoom to the cursor, perspective or orthographic camera, and a view cube that follows the camera.
+- **Selection**: click, Ctrl+click, window and crossing box selection, context menu, hotkeys (H, I, Shift+H, F, Esc), model tree by category with search and a properties panel.
+- **Sections**: up to six section planes moved and rotated with an in-scene gizmo, or a section box that keeps or cuts its inside, with face handles and a box around the selection.
+- **Tools**: point-to-point distance, display modes (materials, textures, white, wireframe), grid lines and global opacity.
+- **Coordination data**: saved viewpoints and a viewpoint tour, clash results, a 4D schedule player and linked-file visibility.
+- **Russian and English interface**, chosen from the browser language.

+- `ViewerDocument`: The root container holding elements, meshes, shared geometries, materials, textures, viewpoints, grids, section planes and box, clash tests, linked files, and 4D schedules.
 - `ViewerElement`: Represents a BIM element (Revit element, IFC product, Navisworks node) with properties and associated mesh parts.
-- `ViewerMesh`: Triangulated 3D mesh geometry with vertex coordinates, triangle indices, normals, colors, and bounding box.
-- `ViewerMaterial`: Visual appearance definition including diffuse color, opacity, metalness, and roughness.
-- `ViewerTexture`: Embedded raster texture data with real-world meter scaling for UV box projection.
-- `ViewerViewpoint`: Saved camera orientation, target, field of view, and projection mode.
+- `ViewerMesh`: Triangulated 3D mesh geometry with vertex coordinates, triangle indices, normals, colors, and bounding box. A mesh can instead draw a shared `ViewerGeometry` (`GeometryId`) and place it with `Transform`.
+- `ViewerGeometry`: Triangle geometry stored once in `ViewerDocument.Geometries` and drawn by every mesh that references its `Id`.
+- `Transform3d`: Affine transform stored by columns (`XAxis`, `YAxis`, `ZAxis`, `Translation`), with `Identity`, `Translate`, `Apply` and `Then`.
+- `ViewerMaterial`: Visual appearance definition including diffuse color, opacity, metalness, and roughness. The HTML viewer uses the color, opacity and texture.
+- `ViewerTexture`: Embedded raster texture data with its real-world size in meters, which scales the mesh UVs.
+- `ViewerViewpoint`: Saved camera position, target, field of view, and projection mode (perspective or orthographic).
 - `ViewerSectionPlane`: Cutting plane defined by axis or normal vector with offset and flip direction.
-- `ViewerSectionBox`: 6-sided 3D clipping volume with fit-to-selection capability.
+- `ViewerSectionBox`: 6-sided 3D clipping volume. Section planes and boxes are kept in JSON snapshots; the HTML viewer does not apply them when it opens.
 - `ViewerTimeLinerSchedule`: 4D construction schedule tasks with planned and actual dates, costs, and progress.
-- `ViewerClashTest`: Clash detection test conflict items with 3D intersection points and status.
+- `ViewerClashTest`: Clash detection test conflict items with 3D intersection points and status. `ViewerClashResult.Element1Id` and `Element2Id` optionally identify the clashing elements; without them the viewer matches an element by name only when the name is unique.

+- `HtmlViewerOptions`: Title, which data to include (properties, viewpoints, grids, 4D schedule, clashes), the initial display mode (`InitialWireframe`, `InitialWhiteMode`), and `MaxMeshVertices`, which is unlimited by default; when a lower limit leaves meshes out, the viewer shows how many were written.
 - `JsonViewerExporter`: Exports `ViewerDocument` snapshots into structured JSON.
 
 ### Importers (`IOViewer.Importers`)

A node hierarchy that is not a tree (a node referenced twice or a cycle) is rejected with `InvalidDataException`.
+- `ObjViewerImporter`: Reads Wavefront OBJ geometry into `ViewerDocument` as is, without changing the up axis. Material (`.mtl`) files are not read.

Subject: [PATCH 37/40] fix: robust CLI export, pickable element-less geometry,
 focus, wheel and bootstrap errors

- HtmlViewerExporter.Save validates the data before it opens the file, so a
  failed export leaves an existing page as it was; the CLI reports
  InvalidDataException/ArgumentException from the export with exit code 3.
- The picker returns { element: -1, point } for geometry without an element:
  orbit pivot, wheel zoom target and the distance tool use the point, every
  selection path still ignores it.
- A press on the 3D canvas or the view cube takes focus from panel fields and
  toolbar buttons, so H, I, F and Esc work after using a panel.
- Wheel zoom scales with deltaY (lines and pages normalised to pixels):
  0.85 per 100 px, clamped to 0.5..2 per event; deltaY 0 does not zoom.
- Startup shows a localized message instead of a blank page when WebGL 2 is
  missing or the model data cannot be read.

 - Transparent objects are sorted per chunk of merged geometry (or per cell of instanced copies), not per object, so overlapping transparent objects in the same chunk can blend in the wrong order.

Subject: [PATCH 39/40] fix: shared-geometry precision, OBJ/GLB elements,
 mirrored winding and sheared instance normals

- Write shared geometry relative to its own snapped origin and move that origin into
  each instance translation (in double), so world-coordinate vertices never reach
  float32 or the viewer's GPU decode as large numbers.
- GLB and OBJ importers create one element per node / object or group, so converted
  models have a tree and can be selected, hidden and isolated. OBJ meshes keep only
  the vertices their faces use; a face referencing an unread vertex fails on load.
- Reverse the triangle winding when baking a mirroring transform into own vertices.
- Transform instanced normals by the cofactor matrix, correct under shear.

Fixes #11

Subject: [PATCH 40/40] fix: list documents without elements by mesh ElementId
 or per mesh

When a document has no Elements, the HTML payload gets stand-in elements for the
written meshes: one per mesh ElementId, grouping its meshes so 4D tasks and clashes
still match it, and one per mesh without an ElementId (marked "mesh": true, which
the viewer never matches against task or clash ids). Such documents can again be
listed, selected, hidden and isolated, as in 0.1.0. The document is not changed.

 - `HtmlViewerOptions`: Title, which data to include (properties, viewpoints, grids, 4D schedule, clashes), the initial display mode (`InitialWireframe`, `InitialWhiteMode`), and `MaxMeshVertices`, which is unlimited by default; when a lower limit leaves meshes out, the viewer shows how many were written.
 - `JsonViewerExporter`: Exports `ViewerDocument` snapshots into structured JSON.
