OpenGL 2.0’s core contribution was the formal integration of the . This was the key that unlocked the black box of the GPU. For the first time, developers could write small programs—vertex shaders and fragment shaders—that ran directly on the graphics processor. A vertex shader allowed complete control over geometry transformation, per-vertex lighting, and skinning. The fragment shader (often called a pixel shader) offered per-pixel control over color, lighting, bump mapping, and shadows.

Leo coded through the night. He created a VBO. He filled it with the vertices of his crystal. He wrote his first Vertex Shader to position the points, and a Fragment Shader to color them. opengl2
