CMake artifact names
Hello, in the CMakeLists.txt for bullet2.8x there's a strange set of lines causing errors for me: +113 SET(CMAKE_DEBUG_POSTFIX "_Debug" CACHE STRING "Adds a postfix for debug-built libraries.") SET(CMAKE_MINSIZEREL_POSTFIX "_MinsizeRel" CACHE STRING "Adds a postfix...

Re: Edge of the world
Indeed! It looks like it.
Guess I'll have to create invisible walls then.
Thanks,

Edge of the world
Hello, I have just played around and replaced an existing btDbvtBroadphase by bt32BitAxisSweep3. Originally I was under the impression that I had to use the former because my world boundaries were unknown. Now I expected that an object that would free fall until the boundaries specified in bt32BitAx...

Re: NASA Tensegrity Robotics Toolkit
Adam, (Sounds like you got it working: https://github.com/NASA-Tensegrity-Robotics-Toolkit/NTRTsim/issues/85) By default, we install Bullet 2.82 with our setup.sh script. If you're interested in helping us upgrade to Bullet 3, let us know! Brian Hi Brian, I hope you still read this response. Are yo...

Re: strength of grabbing 6dof Constraint
Digging deeper revealed the problem on our side.
My bad. Some unknown to me method disabled the constraint in those cases...
Please excuse the noise.

strength of grabbing 6dof Constraint
Hello, I could use a little advice on a problem I'm having with a generic 6dof. Basically, I am using this constraint as picking cursor, much like the demos use point to point. Can can however not use point to point as my picking constraint also needs to rotate the object because this is in an immer...

Re: Solution to the rubber constraint problem?
Hi Erwin,
thanks, that's quite a bit of food for thought. I will give these options a shot and see how I go.
Thanks a bunch,

Solution to the rubber constraint problem?
Hello all, I have generic physics simulation system here based on bullet. It allows people to create constraints and (mostly triangle mesh) shapes to simulate within their own existing application. A little like the Blender integration. So basically everbody likes it and so do I but a major buzzkill...

Re: Center of mass computation for btGImpactMeshShape
There is btRigidBody::getCenterOfMassPosition() you can try.
I remember having done this, it should be possible.

Re: btSliderConstraint
Gimpact, the Bullet 2 softbody, the kinematic character controller are pretty unstable and unmaintained and a support burden. It is not clear what will happen to those parts yet. On the off chance of this getting a bit off topic ;-) I had the impression Gimpact is not maintained that well. However,...

That's an interesting question too.Antonz wrote: There will be also new Issue/Bug tracker for Bullet 3?
I had this assertion bug in Gimpact the other day and didn't know what to do with it other than posting it here. Was there a better way?
Cheers,

Re: btSliderConstraint
Hi Flix, yeah, I got it to work now. Thanks. The trafo needed to be what I know as a "look at" trafo. With that it works as expected. What I am unsure of is how to interpret the parameters of the two-body constructor. Is that sort of a combination of two sliders or how should I read this? ...

assertion in Gimpact collision objects with constraints
Hello, I'm running Gimpact here for concave triangle meshes. So far with success and I like the results. However, when I have a collision of two if those objects caused by a constraint I get an assertion. I have two test cases. a) A cone shaped static Gimpact mesh with a hinge that lets a dynamic to...

Re: Door knocked off hinge constraint by collisions
If I apply small forces to the door it seems to move correctly and respects the angle constraint until... I apply too much force to the door (i.e. through a ball at it with a large mass). Then it kind of "bounces" out of it's location and springs back to its location. The hinge axis will ...
