Unity advanced computer graphics week 02
The document provides an overview of advanced computer graphics concepts in Unity, focusing on the differences between CPUs and GPUs and shader languages such as HLSL and GLSL. It discusses shader compilation methods across various platforms and introduces essential shader properties and data types. Additionally, it outlines several exercises for practical applications, including creating shaders for grayscale, brightness-contrast, and blur effects.

- 7. Shading Language usedin Unity In 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.
