Sample grid p+i.u+j.v+k.w using trilinear interpolation in world coordinates.

Profile points are p+i.u+j.v+k.w, where i=[0..nu-1],j=[0..nv-1], k=[0..nw-1] Vector v is resized to nu*nv*nw*np elements, where np=image.n_planes(). v[0]..v[np-1] are the values from point p Samples are taken along each image plane first, then direction w, then v, and u.

Profile points are p+i.u+j.v+k.w, where i=[0..nu-1],j=[0..nv-1], k=[0..nw-1] Vector v is resized to nu*nv*nw*np elements, where np=image.n_planes(). v[0]..v[np-1] are the values from point p. Samples are taken along direction w first. Samples outside the image are set to 0.
