C2 -- LWJGL Java 3D Engine

Jan 2005: Added scripting support, interactive console
Dec 2004: Added Quake 3 map loader, MD3 model loader

C2 is a small 3D engine prototype based on the Lightweight Java Game Library (LWJGL).

Java provides a comfortable environment to experiment with OpenGL and real-time computer graphics.

Features

Quake 3 Binary Space Partitioning (BSP) map loader
MD3 (Quake 3 animated mesh) model loader
MD2 (Quake 2 vertex-animated mesh) model support
Entity management and scene graph
Collision detection with bounding spheres, OBB (Oriented Bounding Box) and AABB (Axis-Aligned Bounding Box)
Free-flight and 3rd person camera
Curved surfaces
Image format support: PNG, JPG, TGA, DDS (DirectDraw Surface – GPU-compressed textures)
Interactive scripting console

Press ^ on the keyboard to open the console.
