Corange is a pure C game engine built on SDL and OpenGL, providing asset, entity, and UI management plus a modern deferred renderer. It serves as a platform for graphics techniques like shadow mapping, SSAO, skeletal animation, and terrain rendering.

Use cases

• build a game engine in pure C
• learn deferred rendering with OpenGL
• experiment with skeletal animation and inverse kinematics
• render terrain and sea surfaces with shaders
• write a small platformer game in C
• try OpenCL/OpenGL interop for metaballs

When to choose

• you want a lightweight C-based engine to learn graphics programming
• you prefer writing your own 2D renderer and game logic
• you want readable source for techniques like SSAO, shadow mapping, and tessellation

When to avoid

• you need out-of-the-box, plug-and-play engine features
• you want a built-in 2D renderer or full editor tooling
• you need a production-ready engine with active community support
