Opengl 20 May 2026

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 It is the of modern graphics APIs—outdated as a living tongue, but foundational to everything that followed.

Even Vulkan (2016) – which is a thin, low-overhead API – still requires the developer to think in terms of vertex shader invocations and fragment shader outputs, a conceptual inheritance from OpenGL 2.0. If you search "OpenGL 20" expecting the latest version, you'll find a two-decade-old standard. But that standard changed computer graphics forever. OpenGL 2.0 democratized GPU programming. It took shaders from the domain of a few engine architects to every graphics programmer. opengl 20

And a matching fragment shader:

#version 110 varying vec3 v_color; void main() gl_FragColor = vec4(v_color, 1.0); Today, you can run an OpenGL 2
