Open Source C++ 3D Rendering Software

Celestia is an application for real-time 3D visualization of space, with a detailed model of the solar system, over 100,000 stars, more than 10,000 galaxies, and an extension mechanism for adding more objects.

The Retribution Engine is designed for first person shooter games on Windows and Linux PCs using OpenGL and OpenAL. It is supplied with a range of games and levels and includes fully featured level and model editors. On Linux the game and tools work fine using wine/bottles and the game can also be imported into Steam client and runs on proton experimental.

Milk Engine is a flexible engine suitable for almost any game. Milk Engine will contain everything needed to develop a game, even for the newbie. Yet it’s very useful for advanced users. It’s based on OpenGL and SDL, therefore it’s also cross-platform.

An OpenGL 3D game, written from scratch (no dependencies). Provided as freeware mostly as a source of inspiration to help others. A little like a 3D version of the Amiga game Pang! The game is mostly intended for someone wanting to learn OpenGL. But since the game only uses OpenGL 1.0 the drawing code is outdated, but still things can be learned from the collision detection and other techniques. Some of the code is left in an unfinished/testing state. This game was a learning experiment for me, and the math used is tested until it works for the game. After using the science math by the book, there were still flaws that could make the player get stuck under certain conditions (since floating point is not exact), and the workarounds for this are just my own ideas. Have looked at the code for other 3D games and there are mostly the same problems around collision detection and "hacks" to get it to "work".

System for simplifying construction of OGLSL shaders

Panzer is a game where you command a tank and try to take out your enemies. It uses an advanced physics simulation model and is playable over the internet (2-4 players recommended).

C++ wrapper and extension of OpenGL. Provides Scene Graphing natively and cross-platform development through "glue" libraries. "glues" available so far; Qt, X11, GLUT, SDL, Allegro (with AllegGL ), with Win32 to come. Base library depends on OpenGL only.
