This project consists of several 3D objects inside a large sphere that is physically over 32″. Each moon has detailed texture maps including cloud layers and atmosphere.
When this project was first done in TrueSpace in 1997 it was to be a 107 second video of the sphere flying to both moons complete with a musical score. However the rendering then would have taken about 11 months of 100% compute time. So the complete render was not created.
Unfortunately TrueSpace died when Microsoft bought the company. This project may get recreated some day using new tech, maybe Blender.
