Member Function Documentation

void Clear ( )

Clears the stencils from the table.

std::vector<float> const& GetDuWeights ( ) const

inline

Returns the 'u' derivative stencil interpolation weights.

Definition at line 299 of file stencilTable.h.

std::vector<float> const& GetDvWeights ( ) const

inline

Returns the 'v' derivative stencil interpolation weights.

Definition at line 304 of file stencilTable.h.

void UpdateDerivs	(	T const *	controlValues,
		T *	uderivs,
		T *	vderivs,
		int	start = `-1`,
		int	end = `-1`
	)		const

inline

Updates derivative values based on the control values.

Note: The destination buffers ('uderivs' & 'vderivs') are assumed to have allocated at least GetNumStencils() elements.

Parameters

controlValues	Buffer with primvar data for the control vertices
uderivs	Destination buffer for the interpolated 'u' derivative primvar data
vderivs	Destination buffer for the interpolated 'v' derivative primvar data
start	(skip to )index of first value to update
end	Index of last value to update
