The defining feature of , released in 2004, is the introduction of the OpenGL Shading Language (GLSL) as a core part of the API . This moved the industry away from a rigid, fixed-function pipeline toward a fully programmable one, allowing developers to write custom code for vertex and fragment processing. Key Core Features of OpenGL 2.0 opengl 20

While version 4.6 is the current standard, OpenGL 2.0 remains relevant for specific use cases today: Per-vertex lighting calculations
Although technically promoted from an extension to core in later revisions, FBOs arrived alongside OpenGL 2.0’s ecosystem. They allowed rendering to texture without the clunky platform-specific "p-buffers." FBOs became the foundation for post-processing effects (bloom, motion blur, depth of field).
While it is now considered a legacy API, its core concepts—shaders, the programmable pipeline, and efficient GPU management—are more important than ever. They form the bedrock of modern APIs like Vulkan, DirectX 12, and WebGL, making an understanding of OpenGL 2.0 essential for anyone serious about learning the inner workings of computer graphics.
Beyond shaders, version 2.0 introduced several features that became standard for modern rendering: Non-Power-of-Two (NPOT) Textures
