OpenGL 2.0: The Revolution That Brought Shaders to the Masses
Before version 2.0, OpenGL relied on the Fixed-Function Pipeline. Developers could only toggle pre-existing mathematical operations for lighting, texturing, and geometry transformations. If a developer wanted a custom lighting model or a unique visual effect, they had to employ complex multi-pass rendering hacks. opengl 20
: For the first time, developers could write custom code (shaders) that ran directly on the GPU to handle vertex and pixel (fragment) processing. OpenGL 2
While GLSL was the headline feature, OpenGL 2.0 brought several other major upgrades to modernize the API: : For the first time, developers could write
Decades of tutorials, textbooks, libraries (GLFW, GLAD, glm), and open-source engines exist. Where OpenGL Thrives
OpenGL 2.0 changed the game by introducing as a core feature. This allowed developers to write custom code (shaders) that runs directly on the GPU, enabling: Vertex Shaders : Customizing how 3D shapes are transformed.
