Before OpenGL 2.0, 3D graphics were a "cookbook" of fixed operations. After OpenGL 2.0, graphics became a blank canvas of programmable shaders. This article dives deep into why that shift mattered, the core features of the spec, and why understanding OpenGL 2.0 is still relevant for retro drivers, legacy systems, and shader education.

Here's a simple example of rendering a triangle using OpenGL 2.0 and GLSL: Before OpenGL 2
