20 Updated: Opengl

A Vertex Shader executes once per vertex. It replaces the fixed-function transform and lighting. In your GLSL code, you can:

This example demonstrates the basic usage of OpenGL 2.0 and GLSL for rendering a simple triangle. opengl 20

Between these, the (triangle setup) stayed fixed hardware, but shading became Turing-complete. A Vertex Shader executes once per vertex

This approach presented significant limitations: the (triangle setup) stayed fixed hardware

The cornerstone of OpenGL 20 is the introduction of the . For the first time, developers could compile and link small programs called shaders that executed directly on the GPU.
