picasso

Introduction

picasso is a PICA200 shader assembler, written in C++. The PICA200 is the GPU used by the Nintendo 3DS.

picasso comes with a manual Manual.md that explains the shader language. example.vsh is simple example that demonstrates it.

Building

Compiler frontend

A working C++ compiler with at least C++11 Support is required as well as cmake

Building:

cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build

Library

Run the following commands

cmake -B build -DCMAKE_BUILD_TYPE=Release --toolchain /opt/devkitpro/cmake/3DS.cmake
cmake --build build

Installing is not supported (yet)

Shout-outs

• fincs for making picasso
• smea for reverse-engineering the PICA200, writing documentation, working hard & making aemstro_as.py (the original homebrew PICA200 shader assembler)
• neobrain for making nihstro-assemble, whose syntax inspired that of picasso and whose usage of boost inspired me to make my own assembler without hefty dependencies.
