As the topic then was journey and travel is a synonym for journey this seemed like the perfect occasion for a sequel. Of course sequels have limitations. But have a look as see some of 8ball's progress. Legs (introduced in Evolution) and arms and even getting some expressions. Cueball is a genetically modified clone of 8ball which may be illegal in Europe. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The doorway to another world (that has to be traveling) is the same trick as making an image with a picture of itself within it. The desert world is a separate rendering as in image_map on a simple mesh. Visible on one side is in the animation, the mesh isn't there until the camera location is in the -z side of zero. It is done by making a separate set of images in the same aspect ratio as the doorway. The camera for those images moves the same as it will in the composite image. The images are then applied to the mesh in the composite to corespond to the motion of the camera in the composite. Part of this has been developing ways to simulate gravity without having to use Hamiltonian or Lagrangian mechanics. This is to have things fall and jump realistically without the heavy math. Better is the enemy of good enough. Jumping up and down is a sine wave. You can judge for yourself if that is good enough. Falling over is a "linear degrees per frame" squared. Decide for yourself if it is good enough. In the zip file x1.pov shows the squared approach to having the "doorway" fall over. x2.pov shows the sine wave approach to jumping. As usual, gimp was just for the marquee.
