If the previous versions of OpenGL were about using a "fixed-function" menu of options, OpenGL 2.0 was about giving programmers the kitchen and letting them write their own recipes. The Programmable Pipeline: GLSL Takes Center Stage

Earlier versions required texture dimensions to be powers of two (e.g., 256x256). OpenGL 2.0 allowed textures of any size, significantly reducing memory waste and simplifying asset creation. opengl 20

The mobile version of this standard became the backbone of the smartphone revolution. If you played an early 3D game on an iPhone or Android, you were likely using the mobile "subset" of OpenGL 2.0. If the previous versions of OpenGL were about

Scripts that calculate the color of every single pixel on the screen. The mobile version of this standard became the

Before 2.0, developers were largely stuck with the "Fixed-Function Pipeline." If you wanted to light a scene, you toggled a few switches for ambient or specular light. If you wanted something more complex, you had to use obscure, low-level assembly-like extensions.

This improved performance for shadow volume techniques by allowing different stencil operations for the front and back faces of polygons in a single pass. Why Does It Still Matter?

OpenGL 2.0 bridged the gap between the rigid hardware of the 90s and the flexible, "compute-everything" power of modern GPUs. It democratized high-end visual effects, moving them out of the hands of hardware engineers and into the hands of creative software developers.
