False positives in culling test: btDbvt::collideKDOP
Posted: Sun Mar 26, 2017 12:31 pm
Hello, I work on upbge (a fork of Blender game engine).
I noticed that bullet culling test returned false positives as described here: http://www.iquilezles.org/www/articles/ ... orrect.htm
This concerns big objects. I did a test file and a bug report here: https://github.com/UPBGE/blender/issues/443 (it needs to build upbge sources with the patch I shared applied to see the issue).
(This issue is in another function in game engine source code: KX_Camera::BoxInsideFrustum too)
I didn't check at new bullet sources if this has been fixed. We use the same version of bullet than Blender (2.83 iirc).
I wanted to have the opinion of Erwin Coumans about this issue. Is it intended to have a limited amount of false positives to alleviate the culling test or is it an issue?
Thanks for your answer!
EDIT: I can provide a build if you tell me your OS
