Tiny Scene Graph (TinySG) is a lightweight and extensible scene graph manager. It is the successor of my SceneML project.
- Lightweight scene graph.
- Scenes can be saved/loaded from fairly simple XML definitions.
- Fairly extensible scene and object queries supported through a plugin-type framework.
- Current plugins support collision and distance queries based on ODE and the Lin-Canny algorithm respectively.
- Finish porting SceneML's Matlab interface to TinySG
- Finish multithreading scene node update algorithm to take advantage of today's multi-core computers
TinySG supports virtually every primitive geometry supported by ODE (e.g. boxes, spheres, capsules, etc) as well as arbitrary user-defined meshes specified in either OBJ or STL file formats.
