). OpenGL 2.0 officially supported textures of any dimension, significantly reducing memory waste and simplifying asset creation for UI elements and video playback. The Architecture: Fixed-Function vs. Programmable
Here’s the story.
Internally, the driver would translate these legacy fixed-function calls (like glLightfv or glMatrixMode ) into equivalent shader programs. This transparency smoothed the transition period, allowing developers to adopt programmable shaders incrementally rather than forcing an immediate rewrite of their engines.

While shaders stole the spotlight, OpenGL 2.0 shipped with several other critical enhancements.
The fixed-function pipeline was a barrier. Programmers had to mold their creative vision to fit a rigid set of tools. The industry needed flexibility, especially as graphics hardware became more powerful and programmable. On , after years of planning, the OpenGL 2.0 specification was officially released. This was, without exaggeration, the most significant leap in the API's history.
, which allow a shader to output to several buffers at once—a critical feature for advanced rendering techniques like deferred shading. Texture Flexibility : Supported Non-Power-of-Two (NPOT) Programmable Here’s the story
The Official Guide to Learning OpenGL, Version 2, 5th Edition
: Allows a shader to write to multiple buffers simultaneously, which is essential for advanced techniques like deferred rendering Floating-Point Textures
Prior to version 2.0, OpenGL required texture dimensions to be powers of two (e.g., OpenGL 2

Due to its relative simplicity compared to modern, verbose APIs, it remains a fantastic starting point for understanding the fundamentals of shaders and the graphics pipeline. Solving Modern Issues with OpenGL 2.0
