Detailed Description
Base class for a physics engine.The parameters are as follows:
- speed (float)
- Target simulation speed (e.g. speed 2 yields twice real time).
- Default 1.0
- gravity (float vector)
- The gravity vector (m/sec/sec); the default corresponds to Earth gravity.
- Default 0 0 -9.8
- stepTime (float)
- The minimum step time for the simulator. Reducing the step time will increase the fidelity of the physical simulation, but consume more CPU time. If you have particulary complex system that appears to be diverging (i.e., objects "explode" when they come into collision), consider reducing the step time.
- Default 0.020
