Detailed Description

Implements interpolation of a cubic spline curved, defined by a set of control points. The curve will pass through each control point.

Member Function Documentation

int CubicSpline::AddPoint (  const DPoint3 &  vec  )

Adds an interpolation point.

void CubicSpline::Cleanup (   )

Re-initialization.

bool CubicSpline::Generate (   )

Generate the spline coeffs.

bool CubicSpline::Interpolate (  double  par, DPoint3 *  vec, DPoint3 *  dvec = NULL, DPoint3 *  ddvec = NULL )  const

Perform interpolation. Parameters: par  The interpolation parameter, in the range of 0 to N, where N is the number of segments (one less than the number of control points that define the curve). vec  The point that results from the interpolation. dvec  Tangential vector (optional). ddvec  Curvature vector (optional).

int CubicSpline::NumPoints (   )  const [inline]

Return number of control points that define this curve.
