template<class sType , class dType >

void vimt3d_resample_tricubic	(	const vimt3d_image_3d_of< sType > &	src_image,
		vimt3d_image_3d_of< dType > &	dest_image,
		const vgl_point_3d< double > &	p,
		const vgl_vector_3d< double > &	u,
		const vgl_vector_3d< double > &	v,
		const vgl_vector_3d< double > &	w,
		int	n1,
		int	n2,
		int	n3,
		dType	outval = 0
	)		[inline]

Sample grid of points in one image and place in another, using tricubic interpolation.

dest_image(i,j,k,p) is sampled from the src_image at p+i.u+j.v+k.w, where i=[0..n1-1], j=[0..n2-1], k=[0..n3-1] in world co-ordinates.

dest_image resized to (n1,n2,n3,src_image.nplanes())

dest_image.world2im() set up so that the world co-ordinates in src and dest match

Points outside image return zero or outval

void vimt3d_resample_tricubic_edge_extend	(	const vimt3d_image_3d_of< sType > &	src_image,

		const vgl_vector_3d< double > &	v,
		const vgl_vector_3d< double > &	w,
		int	ni,

		int	nk
	)		[inline]

Sample grid of points in one image and place in another, using tricubic interpolation.

dest_image(i,j,k,p) is sampled from the src_image at p+i.u+j.v+k.w, where i=[0..nk-1], j=[0..nj-1], k=[0..nk-1] in world co-ordinates.

dest_image resized to (ni,nj,nk,src_image.nplanes())

dest_image.world2im() set up so that the world co-ordinates in src and dest match

Points outside image return the value of the nearest valid pixel.
