Multitool Linux: Practical Uses for Open Source Software

Getting Fancy

I decided to get a little fancy with the logo and came up with the image in Figure 23-6 . I changed only the coloring and texture for each of the objects. I also added the front and back structures to complete the look. Here's the code to get you thinking about it.

Figure 23-6. Image of fancy 3D logo.

So that's it for the 3D logo. Your introduction to 3D art is not complete by any means. There's a whole lot more to PovRay, and it's worth exploring on your own. PovRay isn't the only avenue for you to explore either. These days there are many new tools available to you.
