OK, here's a quick hack that might give you an idea of what's possible with 3D... <http://www.xmission.com/~legalize/fractals/mandelspire.zip> It contains a single EXE. You will need the DirectX 8.1 runtime installed in order to run the program. It computes a static model from the orbits of points iterated on the M-set. You can rotate the model around with the arrow keys. F2 or File / Config Display... will let you switch to full screen display if you want (also you can change multisampling for antialiasing if your card supports it). This is just a -very- simple example, but going to 3D means that there are many more interesting ways you can 'visualize' the orbits of iterated complex plane fractals, not to mention the fancy things you can do with texturing support. The main fractal part of the code just computes the spires from the orbits of individual points. -- Ask me about my upcoming book on Direct3D from Addison-Wesley!
