About Springhead   
Sprinthead is a virtual reality development environment with a focus on real-time rigid-body motion simulator.
Sprinthead has following feachers as a physics simulator.
- Joint does not come off
 
- Degrees of freedom reduction method (Featherstone's method: not coming off joint) can be used with LCP (contact calculation) at the same time.
 
- Hard to oscillate
 
- Stable simulation (including controller) has been achieved by incorporating spring damper and so on as constraint conditions.
 
- Fast but does not pass through
 
- Judges contact between convex shapes using our own continuous contact determination algorithm.
 
- Simulation states can be stored/restored
 
- Can go back to any time step, and compliant trajectory tracking can be made.
 
Following appliction support functions are provided.
- Can be used from script language Python. Cooperation with built-in Python.
 
- Support for making characters and virtucal robots.
 
- Connecting function with haptic interface (multi-rate haptic rendering).
