Shaders allowed real-time fluid simulation, fractal rendering, and post-process effects (bloom, depth of field) previously limited to pre-rendered CG. opengl 20

Medical imaging could use fragment shaders for real-time volume ray-casting. GIS applications used vertex shaders to warp satellite imagery over digital elevation models. | Feature | OpenGL 2

If you're diving into shader programming for the first time, start with OpenGL 2.0 / GLSL 1.20. It strips away compute shaders and indirect draws, leaving only the elegant core: vertices, fragments, and the code that connects them. Then, when you move to OpenGL 4.6 or Vulkan, you'll recognize every shader-based concept as a direct descendant of the revolution that began in 2004.

Today, you can run an OpenGL 2.0 program on a Raspberry Pi, a Windows 11 PC with Intel integrated graphics, or an Android device via GLES 2.0 (which is based heavily on OpenGL 2.0). It is the of modern graphics APIs—outdated as a living tongue, but foundational to everything that followed.
