Re: strange surface behaviour

hi norbo, I am still working on my project. I added items and the bepu engine does a great job!!!! :D However I found that the sticky-surface-issue occurs when my object/character is standing on a very thin CompoundShapeEntry. Like on a BoxShape with dimensions like (0.5f 0.05f, 0.5f) It also happen...

Re: truncated cone

oh, okay then. But the wrapped shape does compute the convex hull points, and uses them? Which means the parts are not perfectly round then? Like when I use a CylinderShape, the surface on the cylinder is smoothly round, and the wrapped shape is not, right? What I now do, is just create a ConvexHull...

Re: change position when space is freezed

or can I just use the old BEPUphysicsDrawer project and a new version of BEPUphysics and BEPUutilities?

truncated cone

Hi, can anybody help me, how to construct a truncated cone shape? http://www.swiftutors.com/admin/photos/volume-of-a-truncated-cone.png My idea is to use a CylinderShape inside of a TransformableShape. So when I 'distort' a cylinder by shinking its top, it becomes like a truncated cone (and I figure...

Re: change position when space is freezed

very neat, I might want to use contact information, thank you. Forget the part with the debug drawer, I already use InstancedModelDrawer thanks. (the problem I had with objects not showing off when not updating was caused by myself, i add them in the update for whatever reason) Vulkan and dx12 backe...

change position when space is freezed

Dear Norbo, author of so many good answers (thanks!!) In my world it is possible to change thing's position (and orientation) while the world is in an inert state, i.e. I do not call the Space.Update() method but I want to move around objects by setting Entity.Position = ... . If I just do so, colli...

Re: strange surface behaviour

Hi, and thanks for the quick response. The lack of boundary smoothing on compound shapes is pretty good point. I have witnessed this problem in some situations, but it is not that severe I guess. But the problem that I had also occoured when standing on only one of the compound shapes childs. Now th...

strange surface behaviour

Hi, I ran into a problem: I have added things into the physics Space to form the worlds obstacles, like walls and floor. They are all put into an Entity as elements of a compoundShapes with mass 0.0f. And I have a box which I can move around by applying forces upon it (similar to the characterContro...

Re: voxel object vs voxel object collision

Yes, the acceleration hierarchy is constructed when the collidable is created, and using shape.GetCollidableInstance will create all the CompoundCollidables from scratch. So, when I use a mobile mesh and change it a bit, lets say remove 4 and add 4 out of several million, does it also recreate the ...

Re: voxel object vs voxel object collision

It has been a long time and I have been advancing quite a bit, thank you for your help so far and sorry for my frustration statement :oops: Okey, I have used compound shapes as you recommended and it indeed works good :) The performace is quite good as you stated, it starts to get slower with 15.000...

Re: voxel object vs voxel object collision

wow! Thanks so much for your answer, you are great! I think Blockade Runner actually uses BEPUphysics these days. Pah, so the jitter guys should stop advertising their engine with it :x The bepu engine IS the best engine for c# or not?, but it took me three days to get to know that. I dont want to d...

voxel object vs voxel object collision

hi everybody (me newbe), I have tested three other physics enignes and I found bepu ist best for c# . (congratulations and big thx!!) I want to create a game which contains multiple big voxel objects (like star made, blockade runner or space engineers), which behave physically correct. A major chall...
