Real-Time Physics Simulation Forum

I had this in my notes. I think it came from the Wiki. Haven't tried it yet but eventually I was going to need it. Maybe this is what you mean? I'm just parroting, interested to know if it works. reduces the number of vertices to a minimum before using convexhullshape. Example is in bullet/demos/con...

I am using the raycast vehicle on a converted triangle mesh (from irrlicht) and it is working well with some minor issues of jerking while moving. Is it possible your wheel height, radius or suspension needs adjustment. I can stop vehicles that way. Have you set up debugDrawWorld() to ensure the cha...

I was impressed with the video. I downloaded the current version but it's exclusive to 10.7 and I'm still on 10.6.8 throughout the house. I'll update one of the systems and try it out as we have several compound shapes we have to put together in the next few weeks. I'll provide feedback at that poin...

I will venture what probably is a dumb thought. Hopefully someone who knows something will answer. Have you tried changing back to a "normal" stepSimulation statement for a test. After that discussion we had and one other relatively good thread yesterday on stepSim. I finally found one tha...

I know nothing about the wrappers, but http://irrlicht.sourceforge.net/forum/v ... hp?t=32593 is a rewrite of the irrlicht demo to load bsp, using bullet and irrlicht. It was posted by Erwin Coumans.

Also from the way you describe your problem this may also help but I'm just throwing it out there: DynamicsWorld->getDispatchInfo().m_allowedCcdPenetration = 0.0001f; I just realized you were suggesting a solution for my other problem in the "falling through level thread". I hate to say i...

Actually I found a way to get reasonably consistent speed at different frame rates. Maybe it will help you: DynamicsWorld->stepSimulation( ((float)(UpdateTime)) / 1000.0f, UpdateTime / 5 ); Also from the way you describe your problem this may also help but I'm just throwing it out there: DynamicsWo...

I couldn't get cmake to work either. Have you loaded the extras/AllBulletDemosOSX. There is quite a bit there to work with and study.

Setting up functional sources for a real project was pretty easy if you need that.

I can't answer you. But given the low traffic on the forum, it can't hurt to talk between people trying to figure this stuff out. I had the same problem plus, in a widely varying framerate while spawning many vehicles, I also had jerky rendering if I tried to use the sane version of the stepSimulati...

Yes, something like that would be useful if it has an export format (e.g. code) that could be incorporated in a project.

We only use Macs to develop code, but what component is driving mac only?

In this case, the "level" is a btBvhTriangleMeshShape created from a btTriangleIndexVertexArray I created using code Erwin had posted. This "level" is a static rigidbody. The triangles are large in my opinion, about 30 times the character width. Character (ghostObject) is 1 unit ...

I attempted to release memory in the manner I'd read it was supposed to be by removing and deleting objects in the reverse order I'd created them when building the vehicle. I have that working now, but found that two objects could not be released. I'm guessing that perhaps it is unnecessary to delet...

Part of the issue may be that this isn't the right forum to post specific questions about bullet. You'll notice my post below this one as I posted here too, I don't expect any answers :wink:. I reported it in hope the mods will move it to the correct forum. The "feedback" forum seems to be...
