Open GL Vertex and Fragment Shaders
← Transfer Function Examples | ● | OpenGL GLSL Shader →
Recap: Vertex and fragment shaders are a programmable replacement for steps 2 and 6 of the fixed function pipeline.
Shaders have input registers and output registers (excerpt):
Vertex shader:
- in: MVP, vertex position, attributes
- out: transformed vertex position, varying attributes
Fragment shader:
- in: rasterized fragment position, rasterized varying attributes
- out: final color
