Detailed Description

template<class T>
class SeExpr2::Curve< T >

Interpolation curve class for double->double and double->Vec3D.

Interpolation curve class for mapping from double -> double or double -> Vec3D Subject to some interpolation points.

Each segment is interpolated according to the interpolation type specified on the left control point. Interpolation types supported are members of InterpType below.

Valid instantiation types for this are double, or Vec3D
