Detailed Description

Computes interpolating splines using the Catmull Rom algorithm.

This spline is special in that the interpolating spline passes exactly through the specified control points.

Member Function Documentation

static std::vector<float> w2img::CatmullRomSpline::interpolate	(	const std::vector< float > &	x1,
		const std::vector< float > &	y1,
		const std::vector< float > &	x2
	)			[static]

Returns:

y values for the supplied x2. Note that the x values have to be monotonically increasing See also sort_and_interpolate which will sort the x values before calling this method

static std::vector<float> w2img::CatmullRomSpline::sort_and_interpolate	(	const std::vector< float > &	x1,
		const std::vector< float > &	y1,
		const std::vector< float > &	x2
	)			[static]

Returns:

y values for the supplied x2. Will sort the x values before calling the interpolate method
