Detailed Description

This class is a physics system, consisting of pointmasses, connected by springs. It can be used to model a number of physical phenomena, like ropes, cloth, and jelly objects. It contains a Triangle Mesh to define its surface.

Member Function Documentation

void MassSpringSystem::integrate (  float  deltaSeconds  )  [protected]

This function uses a modified Euler integration, which cannot be used using the general state vector method. The integration method is not very physically correct, but ik looks good, and is super stable. Todo: Any way to make this integration method general?
