Collision Detection Issues

[mkmatlock]

We allow free navigation for subjects through our VR environment, and on rare occasions, when a subject runs into the corner of a piece of furniture, or wall, the camera will suddenly jump above the ceiling of the room and continue to use this as the ground level.

I am tracking subject XYZ locations/orientation during the experiment, so it would be possible to reset the subject to the last "normal" location. However, I am hoping for a more elegant solution.

Is there a way to either:
a) constrain camera Y coordinate to one value, or
b) calibrate the collision detection accuracy to fit our scene

I had some success in mediating the problem by putting invisible boxes around complex objects (some furniture), thus simplifying the collisions. There are some additional such adjustments I can make, but so far this has not remedied all of the problems.

Thanks for your help!

Are you using the <viewpoint>stepsize command?

[mkmatlock]

Yes. Stepsize is set very small (0.01).

What happens if you don't use stepsize, do you still have this problem?
