Merlin           Radixin         Moesin

With Povscript+ build 2.1.2_1.34

Here is the script that generated this.

"standard.rot" contains the rotation matrix that will be applied to each surface. In this case, it is 

       by rotation x 180.0
       by rotation z -29.0000
       by rotation y 19.0000
       by rotation x 86.0000
       by rotation y 6
       by translation 0.25 3 3
     by rotation
       0.991596 -0.0524154 -0.118277
       -7.35227e-05 0.914019 -0.405672
       0.129371 0.402271 0.906334
The script that generates the movie file is not nearly as elegant as a single Povray command. It uses Raster3d to raytrace the images. I personally think the surfaces look MUCH better using Raster3d (render), than POVRay.
