* About Springhead [#ecf9b3f8]

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).

See [[Introduction>screenshot]] and [[Document>document]] for details.
