PointInterpolated Class Reference

Detailed Description

The PointSet is designated by a pointer, and the two points by their indices. The interpolation coefficient is in [0,1], such that the intermediate position is between Point1 and Point2:

pos = (1-coef) * mPoint1 + coef * mPoint2

Todo:

: PointInterpolated could be extended to refer to a Mecable, by using virtual functions
