glsl-transpiler

Transforms GLSL source code into optimized JavaScript, enabling WebGL shaders to run without a GPU or WebGL context. Current stable version is 3.0.3. Maintained as part of stackgl ecosystem. Key differentiators: converts vectors/matrices to typed arrays, expands swizzles, applies expression optimizations, and provides stdlib for environment compatibility. Supports both GLSL ES 100 and 300 versions. Can be used programmatically or as a stream via glsl-parser. Suitable for headless rendering, testing, and education.
