Possible bug in PenetrationDepth value?

Hi Norbo, Thanks for your help getting up and running combining BEPU with Helix-3D Toolkit in WPF. I am having trouble getting reliable values back from the contactInfo.Contact.PenetrationDepth variable for determining collisions in non-realtime simulation with very tiny increments of coordinate val...

Re: Hollow objects. Is there an option available other than...

ok, just working my way through this here in case it helps anyone else trying to connect BEPU to WPF. I have managed to debug draw for simple Boxes and it does look like the proportions are correct, however the translation is too low on the Z axis by half of the box's dimensions. I'll have to see if...

Re: Hollow objects. Is there an option available other than...

PS: I'm beginning to suspect that my units are not matching up. This would explain why objects which move around might collide "properly" (their collision objects are offset proportionally to one another, but do not actually fit their respective objects in the same units/coordinates), but ...

Re: Hollow objects. Is there an option available other than...

Thank you - this worked. I had to include a small epsilon value rather than 0 to get desired behavior, since we are erring on the side of generosity (a 10mm x 10mm cube should be placeable directly next to another without collision detection, but due to floating point error margins a value of 0 is n...

Re: Hollow objects. Is there an option available other than...

Thanks. I do have it somewhat working with PairCreated and PairRemoved events, but only between simple Boxes. I am having a lot more trouble with my StaticMesh as in that case I want to test if it contains all of the other Entities, but I will leave that aside for now. A more pressing matter is the ...

Re: Hollow objects. Is there an option available other than...

Thanks - indeed I was able to use the Static Mesh to map to a hollow cylinder mesh programmatically created so I have control over every parameter, even taper like a cross section of a cone. I'm tempted to go the mesh route for box shapes as well to achieve consistency, and so the container is only ...

Re: Hollow objects. Is there an option available other than...

I am reviving this thread to see what would be the best practice in the latest version. In my case, I am doing 3D printing either onto a platform or into a dish, and want to make either a cube (former case) or cylinder (latter case) be the constraint for valid regions to position an STL file in the ...
