Compute tricubic interpolation at (x,y,z), with minimal bound checks.
Image is nx * ny * nz array of Ts. x,y,z element is data[ystep*y+xstep*x] If (x,y,z) is outside interpolatable image region and NDEBUG is not defined the code will fail an ASSERT. The safe interpolatable region is [1,nx-3]*[1,ny-3]*[1,nz-3].

Compute tricubic interpolation at (x,y,z), with bound checks.
Image is nx * ny array of Ts. x,y element is data[nx*y+x] If (x,y,z) is outside safe interpolatable image region, trilinear interpolated value of the nearest valid pixels is returned. The safe interpolatable region is [1,nx-3]*[1,ny-3]*[1,nz-3].
