A path in 3D.
An object or camera can use this object to trace a path in 3D. This is particularly useful in combination with csReversibleTransform::LookAt().
virtual void iPath::CalculateAtTime | ( | float | time | ) | [pure virtual] |
Calculate internal values for this spline given some time value.
Implemented in csPath.
virtual int iPath::GetCurrentIndex | ( | ) | [pure virtual] |
Get the index of the current point we are in (valid after Calculate()).
Implemented in csPath.
