: Allowed for custom geometric transformations and character skinning directly on the GPU.

OpenGL 2.0 allowed developers to replace the fixed transformation and lighting stages with a vertex shader. This small program runs on the GPU for every vertex of the 3D model. It allowed for custom transformations, skeletal animation calculations, and per-vertex lighting that could be passed to the next stage. opengl 20
