Shader pipeline detailed view
Description
Vertex shader
- Inputs: individual vertex attributes (position, colour, normal, texture coord)
- Typical operations: position transformation, lighting computations per vertex, generation and transformation of texture coordinates
- Outputs: transformed vertex attributes.
Primitive assembly and rasterisation
- Inputs: transformed vertices and connectivity information
- Typical operations: determining fragment locations, clipping against the view frustum, back face culling
- Outputs: fragment positions, fragments to be coloured
Fragment shader
- Input: fragments
- Typical operations: assigning a fragment colour based on interpolated colour, texel, etc.
- Output: coloured fragments
