## What it is
A collection of 52 well-maintained OpenGL 3/4 example programs written in C with GLSL shaders, covering topics from basic rendering to glTF loading and 3D Gaussian Splatting. It is an educational codebase built on the GLUS helper library and built via CMake.

## Use cases
- learn modern OpenGL 3 and 4 with GLSL
- example code for shaders and rendering techniques
- how to load glTF models in OpenGL
- 3D Gaussian Splatting implementation example
- reference for framebuffers, SSBOs and compute shaders
- starting point for a C/C++ OpenGL project

## When to choose
- you want readable, tutorial-style OpenGL examples in C
- you need working code for specific techniques like FBOs, waves, or splatting
- you are learning GLSL alongside a modern OpenGL context

## When to avoid
- you need a full game engine or rendering framework
- you want a high-level abstraction instead of raw OpenGL calls
- you need production application code rather than teaching examples

## Facets
- artifact type: learning-resource
- maturity: active
- function: graphics, simulation, developer-tools
- domain: graphics, tutorials, cross-platform
- platform: cpp, c, windows, cross-platform
- tags: opengl, glsl, examples, shaders, gltf, gaussian-splatting, cmake, graphics-programming, game-development, linux, macos, gpu
