When you play a high-fidelity video game, interact with a 3D model on a website, or use a complex data visualization tool, you are likely looking through the lens of .

Shaders are small programs that run directly on the Graphics Processing Unit (GPU). They are written in , a C-like language. Modern OpenGL is "programmable," meaning you have total control over how vertices and fragments are processed. 3. Buffers and Objects OpenGL uses various "objects" to manage data:

Unity and Unreal Engine support WebGL, but often with stripped-down features. Games using can utilize advanced post-processing effects (bloom, depth of field) that require multiple render targets and framebuffer objects—something WebGL struggles with at high resolutions.
