Do You know the STUNT GP car game? I like it. I am very interested in Your oppinions about some thing in STUNT GP: 1.) What type of accelerating method could that use (BSP, Octree,...) 2.) How could it make the road transparent? (with partly transparent textures) And how could it combine it with the method in 1.)? 3.) How could it make the shadow of the cars to the road? 4.) How could it "knows" the position of the car (if you go into wrong direction or you fall down from the road) 5.) How could it does the collision detection? I am waiting for Your ideas, codes, opinions!! b.r. HunSoul

Please don''t repost your messages in other forums. You are asking questions about subjects that take people months to master. No one can explain all that to you on the message board.
Sorry I am no help; I am not familiar with that game.

i bet jeeves knows.

Have you ever got a straight answer out of jeeves?
In contrast, have you ever not got a straight answer out of google?

HunSoul,

Please send your broad questions one-at-a-time into different threads. You''ll find that people find it annoying to read a long list of general questions. They usually will not respond, or may not provide a serious reply. One question per thread may result in better response. You''ll get better response still if you make your questions more specific, rather than more general.

Also, please move your questions 2 and 3 to a graphics forum. Although they do involve math and physics, you really seem to be asking about graphical techniques.

One further piece of advice. Try searching the forum archives before posting general questions. You should find many, many threads on octrees, BSP trees, collision detection, physics, shadows, transparency, and maybe even on the game STUNT GP.
