Before version 2.0, OpenGL relied on a . This meant the mathematical operations for lighting and geometry were hard-coded into the drivers. If a developer wanted a unique visual effect, they were limited to toggling pre-defined switches.
The most significant feature introduced in OpenGL 2.0 OpenGL Shading Language (GLSL) Animation World Network This milestone replaced the fixed-function pipeline with a programmable pipeline
This feature allowed a fragment shader to output different values to multiple buffers simultaneously. MRTs laid the groundwork for advanced rendering techniques like deferred shading, where geometric data (normals, depth, diffuse colors) is saved into separate textures for complex lighting passes later. Understanding the OpenGL 2.0 Shader Workflow
A critical aspect of the OpenGL 2.0 release was its commitment to backward compatibility. Despite introducing a radical new way of rendering, the API maintained the existing fixed-function entry points. A developer could run an OpenGL 1.5 application on an OpenGL 2.0 driver without changing a single line of code.
And deep in the heart of the driver, the old, rigid pipeline didn't die. It simply put on a new cloak. A call to glBegin(GL_TRIANGLES) was now secretly translated into a short, efficient GLSL shader behind the scenes. The dinosaur had not been replaced. It had learned to code.
Prior to 2000s hardware, textures were strictly required to have dimensions that were powers of two (e.g., 256x256, 512x512). OpenGL 2.0 made NPOT textures a core feature, allowing arbitrary image sizes (like 800x600) to be used efficiently without manual padding or resizing.
The problem was profound. OpenGL’s soul was its stability. Adding a full programmable shader model would be like grafting jet engines onto a steam locomotive. But the alternative was irrelevance.
Prior to version 2.0, textures were strictly constrained to dimensions that were powers of two (e.g., 256x256, 512x1024). OpenGL 2.0 added core support for textures of arbitrary dimensions (e.g., 800x600), simplifying UI rendering and video playback.
