saturn texture map
Saturn is another oblate gas giant, like Jupiter. It is 10% shorter than it is wide — very visible to the eye when viewed through a telescope — so be sure to include this detail in your model. Its ring structure is a bit of a problem to render correctly as well. In Cinema4D I used a finely divided "plane" primitive, with a "bend" procedural object as its child. The plane object had the color and transparency maps applied to it with UV mapping so that when the bend object twisted it around into a 360° circle, the texture stuck to it and bent smoothly with the plane. A similar trick can be accomplished in Lightwave with morph targets.

This map was borrowed wholesale from Björn
Jónsson's excellent map site, as I found his map based on Voyager data to be much superior to my own handpainted effort. |

The color map for the rings was created by myself in Photoshop, using Björn
Jónsson's Saturn ring map and a reference photograph of Saturn for a guide. Cinema4D has a shader for Saturn's rings built into the program, but I think the color bands produced by this map create a better result. The transparency map is also from Björn's site, but flipped horizontally to fit with Cinema4D's mapping peculiarities. |
