Re: Problems with collision and fast objects
As you scale down more and more, you will run into the default tuning factors. The 'energy' is probably coming from a combination of high relative velocities causing deep penetration and a strong penetration correction force relative to the scale. The speed achieved by penetration correction impuls...

Re: Collidable geoclipmapping terrain
A single terrain can handle immense numbers of triangles because the acceleration structure is implicit. Evaluating which triangles are nearby is a constant time operation. The trickier part would be updating the bounding box when you change the terrain. Computing a tight bounding box visits every ...

Re: Collidable geoclipmapping terrain
Out of all the options, Terrain is probably the best fit. Terrains do not have to construct or reconstruct an acceleration structure when they're created or changed because the acceleration structure is implicit. However, making modifications to any static object will result in issues if there are ...

Re: Problems with collision and fast objects
I finally decided to go for it and reduce the scale of the world. I was running a setup where a person had the eye level at 10 units, a box was about 3, a barrel was 6, etc. In this setup I used a gravity of 30 *g, but probably 20 *g would have been enough for objects not to be floaty. Under the new...

Re: BEPUphysics v1.2.0 released!
Indeed, I misread the date. Classic dead thread forum syndrome.
I got all excited about a new version too! Still, the change log for 1.2 looks great and I'm glad I am already running with the changes.

Re: BEPUphysics v1.2.0 released!
Wow, excellent news! The change list looks great! Thank you for your hard work! I am still using BEPU with great success, even when physics gets wonky. Been meaning to ask a few questions for a while, but I'll search the forum first. I'll update to 1.2 soon! But let me squeeze in a a question here: ...

Re: Problems with collision and fast objects
Hi Norbo! Thank you for the quick reply. I should have started by saying that I do not use a fixed time step. I went through the list and tried the changes you proposed to see what effect they have. Calling Update(dt) with the elapsed seconds between frames did wonders to make the game run at a more...

Problems with collision and fast objects
Hi everybody! I am having some problems with object passing though other objects. This happens mostly with fast objects. I saw some other post on the forum about this subject, and based also on my observations, it does seem that the collision check would take place between two time steps and this is...
