I was using `btCollisionWorld::rayTest` to test gun bullet (bullet as in projectiles, not the library) collisions against obstacles; when I noticed bullets were going through obstacles too often and from...
I want to load deformable object in PyBullet with function "loadSoftBody". I know that PyBullet offers example object file "torus.obj" and "torus.vtk". It works well. However, when I try to...
contact->m_cti.m_offset is contact distance, not the negative of it. For example: https://github.com/bulletphysics/bullet3/blob/39b8de74df93721add193e5b3d9ebee579faebf8/src/BulletSoftBody/btSoftBody.cpp#L549
This adds the ability to call `getBaseVelocity` on a softbody in bullet/pybullet - see https://github.com/bulletphysics/bullet3/issues/4445 for more info
Calling `getBaseVelocity` on a softbody does not seem to produce meaningful results in Pybullet. Interestingly, I tried printing this info via modifying the C++ source, and I was able to...

I want to connect two rigid objects (or a static world and a rigid object) using a hinge/rotary constraint. Eg. A gear loaded from a URDF file. * Long story...
Hi, I am new to pyBullet. I am running on Windows 11. I am trying to run the simplest initial code: import pybullet as p import time physicsClient = p.connect(p.GUI)...
The `btMatrix3x3::inverse` code is: ``` btScalar det = (*this)[0].dot(co); btAssert(det != btScalar(0.0)); btScalar s = btScalar(1.0) / det; ``` And the `dot` code is: ``` return m_floats[0] * v.m_floats[0] +...
I was reading the Bullet Physics manual and noticed the following statement regarding the stepSimulation method: "To decouple the application framerate from the simulation framerate, an automatic interpolation method is...
