[ODE] Trimesh and sphere collision

[Jon Watte]

There is no known problem with trimesh/sphere or trimesh/box 
collision. Searching the forums for the last few weeks for 
"car" and "trimesh" will find several posts that talk about 
how to do it -- it seems everyone's up to it at this point.

I've been referencing my simple car demo that's set up almost 
exactly like you say yours is; you might want to download it 
and compare what it does against what you do:

Subject: [ODE] Trimesh and sphere collision


Hi,

I am working on a car race game, and i am using one trimesh as the road, one box as the car chassis and four spheres as the car wheels. I am having some problems with the car/road collision: when the wheels hit the road, it detects the colission of the wheels with 4 collision points (one per wheel) but the car keeps faling through the road. When the chassis hit the road, eight collsion points are detected, and the car stops falling.

Observing these results, it seems that there is some problem with the ODE trimesh-sphere collsion function. Dows anyone have an idea how to solve this problem?


Thanks in advance for your help,
Joao Rangel
