void vil3d_sample_profile_trilin	(	vecType *	v,
		const vil3d_image_view< imType > &	image,
		double	x0,
		double	y0,
		double	z0,
		double	dx,
		double	dy,
		double	dz,
		unsigned	n
	)

Sample along profile, using trilinear interpolation.

Profile points are (x0+i.dx,y0+i.dy,z0+i.dz), where i=[0..n-1]. Vector v is filled with n*np elements, where np=image.nplanes()*image.ncomponents() v[0]..v[np-1] are the values from point (x0,y0,z0) Points outside image return zero.

Sample along profile, using trilinear interpolation.

Profile points are along the line between p0 and p1 (in image co-ordinates). Vector v is resized to n*np elements, where np=image.n_planes(). v[0]..v[np-1] are the values from point p Points outside image return zero.

void vil3d_sample_profile_trilin_edgena	(	vecType *	v,
		const vil3d_image_view< imType > &	image,
		double	x0,
		double	y0,
		double	z0,
		double	dx,
		double	dy,
		double	dz,
		unsigned	n
	)

Sample along profile, using safe-extend trilinear interpolation.

Profile points are along the line between p0 and p1 (in image co-ordinates). Vector v is resized to n*np elements, where np=image.n_planes(). v[0]..v[np-1] are the values from point p Points outside image return NA.

Sample along profile, using safe-extend trilinear interpolation.

Profile points are along the line between p0 and p1 (in image co-ordinates). Vector v is resized to n*np elements, where np=image.n_planes(). v[0]..v[np-1] are the values from point p Points outside image return nearest valid voxel value.
