Shader Languages
Cg (short for Central Graphics) - nvidia
GLSL (glslang) - OpenGL
HLSL (High-Level Shading Language) - DirectX
Shading Language used in UnityIn Unity, shader programs are written in a variant of HLSL language (also called Cg but for most practical uses the two are the same).
Shader Compilers
- Windows & Microsoft platforms (DX9, DX11, DX12 and Xbox One) all use Microsoft’s HLSL compiler (currently d3dcompiler_47).
- OpenGL Core, OpenGL ES 3 and Metal use Microsoft’s HLSL followed by bytecode translation into GLSL, using a modified version of hlslcc.
- OpenGL ES 2.0 uses source level translation via hlsl2glslfork and glsl optimizer.- Other console platforms use their respective compilers (e.g. PSSL on PS4).
Surface Shaders use Cg 2.2 and MojoShader for code generation analysis step.
