You probably need to approximate the half-sphere with a mesh or points on the sphere, and then use a btShape like btGImpactMeshShape (if you have triangles) or btConvexHullShape (if points; or a shape that derives from btConvexShape). Hope this helps. Sorry, I'm pretty new to bullet myself. :( Than...

I have no idea about how to create hemisphere shaped rigid bodies. In addition, I want to create shape like roombots. ( http://biorob.epfl.ch/roombots ) How can I create the shape like that (cutdown parts of hemisphere)? Because I only have dealt with boxshape before and I can't find useful document...

stepSimulation Time is set to be 1/100.

However, it doesn't return the same motion.
I have no idea.

Though I can get really same results with toy problems, I can't get the same results with complicate simulation...

I am a beginner of Bullet Physics, but I have a question about its performance. I am simulating quadruped robot in Bullet Physics world. I set some parameters(constant) to let the robot move, and record the distance(>0) which the robot move in 3 seconds. But the result(motion) is not same at each ti...
