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.
Special effects like procedural texturing, bloom, and distortion.
GLSL allowed developers to write high-level graphics code using a syntax based closely on the C programming language. This removed the agonizing need to write low-level GPU assembly code or rely on vendor-specific extensions. The Vertex Shader opengl 20
Developing graphics in OpenGL 2.0 requires managing data transfers between system memory (CPU) and graphics memory (GPU). Below is a typical breakdown of how an application initializes and executes a shader program. 1. The Shader Lifecycle Shaders are treated similarly to traditional C programs:

OpenGL 2.0 was far more than a simple version update. It was a watershed moment that democratized real-time graphics programming, moving the industry from rigid, fixed-function hardware to the vast creative freedom of the programmable pipeline.
