This interesting project here seems to be more in the Super Monkey Ball direction I think. ^^quasist said:I hope that Trackmania Series will suck to this project
A track Editor like in Stunts for example would be awesome for any 3D racing game. ^^

Do not forget that STUNTS had a secret terrain editor also.
I know, the GP2X has no real 3D skills but maybe it's possible, when I look at the effects of "Payback" ^^
Even the mock-up renders got me rather excited.Payback game engine is a port from GameBoy Advance(16.8 MHz), so rendering and sound eats almost every of both CPUs( at bigger than 200 MHz by default). Althrough there still texture distortions. I think that Payback is not a car simulator - it is a GTA simulator.fusion_power said:

Yes, I know. I just meant the effects, a GP2X can show.
And yes, Payback has this PSX-like Texture distortions. I think it's ok. Without 3D harware, perspective corrected Textures are not possible I know, and even with 3D Hardware, it's sometimes not possible - see Playstation 1 and their funny bended and jumping textures :lol:.
The Balrog of Burnout dragged me into the depths of the Khazad-Dum of Mundane Life, but I have emerged as Dzz The White!PokeParadox said:

I'm mostly pleased with the drawing, which is a tradeoff between quality and performance, like everything else. I still might have to squeeze some more speed out of it, but it will do for now.
If you want to play with a little test app, get:

L/R, A/B, and X/Y rotate on different axes, and the joystick zooms.
Next I want to move the light around and get the spinning completely worked out, before moving on to thinking about how to do the tracks.
Nice. Do you rotate the textures or the polygons?

very good progress !
you just need to add 2 paddles and you can do a 3D pong

Probably "the textures" is the answer, although the actual method is more like simplified ray tracing. For each point, calculate the intersection with a sphere, then apply the rotation matrix to the result to either give the basis for a procedural texture (like the middle marble) or the means to look it up in a texture map (by converting to spherical coordinates and using theta and phi as the texture coordinate). Then apply ambient, diffuse, and specular lighting. It's fairly processor-intensive but as long as the marbles aren't too huge it should be within budget. And I think I will move this particular calculation to the second processor in the end, as its memory bandwidth needs are fairly modest.A_SN said:
-Just an Idea to save processor Power....maybe... ^^As I had envisioned the game prior to starting (such visions never survive intact, but still), there would be sections of a track where (because of obstacles, tight turns or other reasons) the marbles would have to roll slowly -- to give a contrast between slow movement and giddy roller-coaster-like movement. However, you're right that at high speed the way they are drawn is probably not the best because the texture flickers instead of blurring. That's an issue for later but it's an important one, because the player will have their own marble spinning fast right in the middle of their view for most of the game, so that should look decent.fusion_power said:Impressive marble effects for a GP2X, very nice.
Your method looks superb, maybe to good for just a quick racing game. :lol: For max. performance, maybe the spheres could be less round and while high-speed rolling, a more simple animation method could be used. In a fast racing game, the marbles would spin very fast, so you don't see a rotating texture, just blurring or light effects like fading light hue and brightness and so on at the surface of the marble. And what is not seen, is not needed to be animated I think. The "cheapest" way would be a non rotating sphere with a "looped" little texture animation at the surface - not calculated in real time, just something, that gives the effect of a fast spinning marble. maybe in combination with light effects. This could come in handy, when the marble spins very fast. With low speed, your detailed method could be used.
