hi all,

I am developing a 2D car racing game for mobile devices(nokia 60/40 series) using J2ME with perspective view.I don`t have much ideas about it.

I want some thing like this (please see these URLs)

I have some questions

1) what is the
math involved with perspective view

2) how to implement it

3) which type
of map representation will be there (if any) ?

regards

"1) what is the
math involved with perspective view"

Trig & Algebra II
It's just 3d projection calculations.

"2) how to implement it"
Depends how you want to go about it. Do you want to go for a more fake view found in the pictures you posted? If so you can fake alot of that with precalculated tables and using a patern on the rode to give a sense of speed.

Or if you want to go full out Mario Kart style. Then you have to get a bit more complicated with using a viewing matrix and projecting to the floor. There is a good tutorial on the basic informaiton on how to do it for gba by dark fader but you can easly take the concept and apply it to cell phones.

That is up to you.


I hope that gives some help
