To get started, clone the repo (-recursive) and build using CMake. Run example: ./glsl2msl TestData/symbol_sdf_fragment.glsl frag test_symbol_sdf_fragment.msl. View test input and converted output in TestData/.
The converter will define SPIRV for you to perform conditionals with inside your GLSL. A preamble will also be injected along with a default version directive if none is found. By default, this is #version 310 es. The preamble:
- Aliases texture2D to texture
- Aliases gl_FragColor to FragColor
