StaticTriangleGroup backside triangle cull
Posted: Sat Jun 28, 2008 5:37 pm
Is it possible to not collide with backside facing triangles using StaticTriangleGroup? If yes, how that could be done? Thanks in advance
Easily... no.
If you REALLY want to do it... you could raycast agaisnt the triangles from the object multiple times from all of its verticies going in the velocity's direction. (note: the actual triangles, not the StaticTriangleGroup, it returns null entities) Then check the order of the verticies (if they are facing, or not facing the object), and then add it to NonCollidableEntities of the object thats going to collide....
That would 'work' but it would probably have a very large amount of bugs as well as be extremly slow.
