Observer falls throught triangle terrain

[ghost]

Hi, in my WalkOnTheMoon Applet, the observer is a sphere object. Unfortunately, if I do not set damping on the observer, it can happen, that he falls through the terrain. I can help fix this, but I need to know, which files are to be touched. Sincerely Thorsten

If the problem occurs only with spheres, then the relevant file is probably GimTrimeshSphereCollision.java. Otherwise it could be anywhere else (AABB checks, space collision, ...?). I think this is a known bug, even in the ODE C/C++ version, so it may be hard to fix, i.e. not just a type, but a conceptual problem with the trimesh collider.

Most definitely, ODE has a problem when colliding with heightfields, whoch also tend to let objects fall through. So the problem may be somewhere in ODE/ode4j, not in Gimpact.

But any contributions are highly welcome.

Probably not relevant anymore. Please open new issue if it is observed again.
