Quadratic interpolation is used to determine the output values.
For a fully interactive application with capabilities similar to rot3d, use Rotate3D . Priism Angle rot3d takes as an input three angles which are the rotations to be applied to the x'', y', and z coordinate axes. The angles are assumed to be in degrees. A positive value to the x angle rotates the positive z' axis towards the positive y' axis. When only rotating about the z axis, this sign convention is opposite of that used in Resample2D .
