Quaternion Based 6DOF Spring Joint Constraint

4

Hello, I saw that there was a "demand" for Quaternion Based 6DOF Spring Joint Constraint calculation: https://github.com/bulletphysics/bullet3/issues/4162 https://pybullet.org/Bullet/phpBB3/viewtopic.php?t=8153 So I made a new class: # btGeneric6DofSpringConstraintQuaternion Based on btGeneric6DofSpring2Constraint. This...

Documentation of InvertedPendulumBulletEnv-v0 lacks observation dimension information

3

I noticed that the inverted pendulum Gym environment (https://github.com/bulletphysics/bullet3/blob/master/examples/pybullet/gym/pybullet_envs/gym_pendulum_envs.py) is 5-dimensional, which is different from the usual 4-dimensional observation vector: [cart position, cart velocity, pendulum angle, pendulum angular velocity]. What...
