Video showing the 3D rendered scene in Gimpel3D.
Wigglegram (made with just 2 frames). The left and right images were obtained in Gimpel3D. The stereo window (viewing plane in Gimpel3D) was placed right at the block's leading edge.
Gimpel3D can be used to generate the left and right images for different eye separation values. Those in turn can make up a nice wigglegram. Frame Sequence Generator 4 (FSG4) can also be used to generate the left and right images for an equally nice wigglegram.
I am not a big fan of the anaglyph format, mostly because it requires red-cyan glasses which not everybody has or even want to use. I much prefer an animated 3D gif (wigglegram) or a 3D rendered scene.
