I came up with a nice animation strip for a four-pointed, Japanese-style star that I have just done in PSP X, and coded into an animation program with Blitz 3D. However, it's not exactly 3D unless it's ported into Maya, and placed with a camera to freely roam around the rotating star. Now, instead of the four-pointed star, I'm looking at adding two more points in the other direction, to make like a 3-D compass of sorts that you could rotate around. This looks great, but it's only half-way there. It would look cool to set the animation into both rotating on the X-axis, and the Y-axis, well, it's good for the 2D rotation so far, but to make a 3D rotating star, I need the extra two points. This is where I am so far, just need to use Maya PLE at very least to make this come together with the 6-pointed compass star. Here's the 4-pointed 2D star below:
Of course, the image is bigger than this to use for the actual program. I'll have to see how doing all of this in Maya will handle. I think Maya PLE will also do what TerraGen will, but you just have to make the terrain from scratch unlike TG. This may be a little complex, but to make a 3D environment and an interactive animation, that's going to take a while.
