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.
