Rotation3d

Interpolation function

SYNOPSIS

#include "dip_interpolation.h"

dip_Error dip_Rotation3d ( in, out, alpha, beta, gamma, method, bgval )

DATA TYPES

binary, integer, float

FUNCTION

This function rotates an 3-D image in via the three Euler angles alpha, beta, gamma to out using nine skews. The first rotation is about alpha around the initial 3-axis. The second about beta around the intermediate 2-axis and the last about gamma around the final 3-axis. The function implements the rotation in the mathmetical sense, but note the Y-axis is positive downwards! The rotation is over the centre of the image.
