Detailed Description

template<typename Type, typename Parameter>
class oglplus::CubicBezierLoop< Type, Parameter >

A closed smooth cubic Bezier spline passing through all input points.

This class constructs a closed sequence of Bezier curves that are smooth at the curve connection points. The control points between the begin and end points of each segment are calculated automatically to make the transition between the individual segments smooth.
