Collision Detection Issues
 

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 stepsize command?

Yes. Stepsize is set very small (0.01).

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