示例1: CalculateTimeOfImpact
public override float CalculateTimeOfImpact(CollisionObject body0, CollisionObject body1, DispatcherInfo dispatchInfo, ManifoldResult resultOut)
{
//(void)resultOut;
//(void)dispatchInfo;
///Rather then checking ALL pairs, only calculate TOI when motion exceeds threshold
///Linear motion for one of objects needs to exceed m_ccdSquareMotionThreshold
///body0.m_worldTransform,
float resultFraction = 1.0f;

return resultFraction;

//An adhoc way of testing the Continuous Collision Detection algorithms
//One object is approximated as a sphere, to simplify things
//Starting in penetration should report no time of impact
//For proper CCD, better accuracy and handling of 'allowed' penetration should be added
//also the mainloop of the physics should have a kind of toi queue (something like Brian Mirtich's application of Timewarp for Rigidbodies)
