Cg (short for C for Graphics) is a high-level shading language developed by Nvidia in close collaboration with Microsoft for programming vertex and pixel shaders. Cg is based on the C programming language and although they share the same syntax, some features of C were modified and new data types were added to make Cg more suitable for programming graphics processing units. This language is only suitable for GPU programming and is not a general programming language. Read more on Wikipedia...
// input vertex
struct VertIn {
float4 pos : POSITION;
float4 color : COLOR0;
};
// output vertex
struct VertOut {
float4 pos : POSITION;
float4 color : COLOR0;
};
// vertex shader main entry
VertOut main(VertIn IN, uniform float4x4 modelViewProj) {
VertOut OUT;
OUT.pos = mul(modelViewProj, IN.pos); // calculate output coords
OUT.color = IN.color; // copy input color to output
OUT.color.z = 1.0f; // blue component of color = 1.0f
return OUT;
