Summary
Adds a feature-deep-dive page for the new HTML-in-Canvas support:
HtmlTexture(core,Materials/Textures/HTML) rendering live DOM into a WebGL2 and WebGPU texture.HtmlRaycastInteractionManager(any mesh, UV-based) andHtmlInteractionManager(planar overlay, native hit-testing) — both in core, tree-shaken unless imported.@babylonjs/addonspolyfill installer (InstallHtmlInCanvasPolyfill,IsHtmlInCanvasSupportedNatively,UninstallHtmlInCanvasPolyfill) that lazily pulls inthree-html-render.Page lives at
content/features/featuresDeepDive/materials/using/htmlTexture.md.Notes
<Playground>embeds or images yet — examples are inline code blocks because the underlying API is experimental (native behindchrome://flags/#canvas-draw-element, or via the polyfill). A live Playground can be added once the API is broadly runnable.Opening as draft pending the engine PR.
