I think there was a griefer in the west region:

I might make the player a sprite, so then it should be possible to show a different sprite when an arrow is pressed

The track will keep being wireframe. Texturing all of that would be way to slow, so I'm only going to use textures for objects (item boxes, turbos, decorative items next to the track) and for a part of the car, so you can easily see which one is yours when the ai comes in.

I'm sorry, but a fully textured 3D track isn't within possibilities of my 3D engine. It could handle it, but with probably around 5fps. Even with a lot of optimisation, you can't make it fast enough.

Maybe you should add in the connect to computer section that any USB A to USB mini B cable works, so you can take one from a digital camera, a playstation, an external hard drive,...

WARNING: THIS POST IS OUTDATED!

This is the project I've been working on since the start of the contest. I haven't done much yet because I'm busy with exams lately.

It is going to be a racing game in which you race against AI, and there will be some items you can use to go faster or to slow down other players (similar to mario kart).
It uses the 3D engine of my other game (Alien invasion), but this one is improved and supports textures, solid triangles and wireframe, instead of only textures.
This is what I have so far:

This is the track, which already works graphics-wise, but it hasn't got any collision checking yet. The track is fully wireframe (and will probably stay like that). The track is fully 3 dimensional, which means it can go left, right, up and down, but models for up and down haven't been created yet. The cube in the center of the screen is the placeholder for the car. The car will probably be mostly wireframe, to fit in the simulation-like theme of the track (of which the current name, 'cyber racer', comes).

Right now the graphics are quite bad, but I might add some models to the sides of the track as illustrations, if the speed will allow it when AI and items are added). Right now, it runs in 15MHz mode, and has 18 fps. But it still looks smooth.

I guess that's all I can say about it now.
For this project I can't include the source because of the rules of the contest. If you want to use the 3D engine in your own project, I can give you the engine of my previous project.

It's a bit hard to read, could you make it a bit clearer? Maybe by doing the background in gray.
The rest looks good.

Looks nice. Do you draw everything pixel by pixel or do you use one of java's build-in methods to render the textures?

Also 52 fps sound a bit slow. Does the framerate drops much when you add more models?
