Re: Changing background color or texture?

Regarding this, I find myself unable to change the background color (which will remain light purple) either in the GUI window or in DIRECT mode when using the code above. I have experienced this issue with pybullet 3.2.5 on the following OS/python versions - python 3.9.12 on MAC OS 11.6.5 - python 3...

Re: p.getCameraImage stuck after a few calls

I did solve my issue by switching to 'eglRenderer', e.g., by adding the following lines (from https://github.com/bulletphysics/bullet3/blob/master/examples/pybullet/examples/eglRenderTest.py ) upon initialization: # Initialize pybullet connection_mode=p.DIRECT self.ch = bc.BulletClient(connection_mo...

Re: p.getCameraImage stuck after a few calls

I do experience a similar issue - querying p.getCameraImage for a large number of times causes the function to hang. I am using pybullet.ER_TINY_RENDERER. Has anyone else experienced the same issue and found a solution?

Bad inertia tensor properties, setting inertia to zero for link

When trying load an URDF via loadURDF() with flag URDF_USE_INERTIA_FROM_FILE I have noticed that pybullet will set the inertia to zero if the sum of the inertia on two principal components of the inertia tensor is smaller than the third remaining (for example if i_xx + i_yy < i_zz), throwing the err...

Re: What is the sequence of rotations applied by "getEulerFromQuaternion"?

Thank you for your reply. I was referring to the "getEulerFromQuaternion" method in the python interface. I have just noticed that the output of help() says that getQuaternionFromEuler(...) Convert Euler [roll, pitch, yaw] as in URDF/SDF convention, to quaternion [x,y,z,w] so is potentiall...

What is the sequence of rotations applied by "getEulerFromQuaternion"?

As in the title, how are the Euler angles provided by the getEulerFromQuaternion method computed?
What is the sequence of rotations (about x, y, z, but in which order?) and they are computed in a fixed frame or in a moving frame (intrinsic or extrinsic)?
Thanks!
