I have elements with 150 vertices each. How many of these can I add in a Bullet simulation?
Assuming Memory is not an issue.

objects not visible after a while
When I implement my objects in PyBullet, everything seems to work fine. However, after I reach a few thousand objects, they do not become visible anymore. Can this be fixed?

Could getContactPoints() return deltaContactVelocity?
getContactPoints() returns quantities such as contactDistance. Earlier, lateralFriction and lateralFrictionDir were also exposed. Could the (relative) contactVelocity be added to this function? It is for damping purposes.

How to change contact force between elements
Hello, I'm wondering if it is possible for Bullet Physics to run a simulation, but use an alternative function for the forces between objects. For example: setting a custom stiffness of two colliding objects, without influencing interactions with other objects. Or setting a stiffness depending on ti...

Setup Bullet Physics World
I would like to setup Bullet Physics in Visual Studio (C++). Therefore, I would like to see a physics world, and load some .obj files. However, I'm stuck at a few places: the Hello World example doesn't show anything (visual), the benchmark 3000 boxes works well, but doesn't load .obj files, the Imp...

Concave objects do not interact?
I've added two concave objects to my simulation. However, these fall right through each other, meaning that there is no interaction between these particles at all. [PyBullet]

How to calculate the volume of an object?
Hello,
I'm sure PyBullet uses the volume and other properties of objects to determine the physical quantities such as intertia.
How can I acces this info? Or calculate the volume of an object?

How to re-use collision shapes among rigid bodies
In the Bullet Physics Hello World example, the following warning is made: "make sure to re-use collision shapes among rigid bodies whenever possible!" However, in PyBullet this is not mentioned. I wish to speed up computation speed, as well as add more objects. In my project I have to work...

add more than 1500 objects in PyBullet
Hello,
After loading more than 1500 objects in PyBullet, they don't appear anymore on the screen.
What causes this and how can this be changed?
Kind regards,
Mark

find center of mass
How can one find the center of mass of an object (.obj file) in PyBullet? getDynamicsInfo() doesn't return it, nor does getCollisionShapeData(), and resetBasePositionAndOrientation() uses the link position, which is assuredly not the center of mass. applyExternalForce() also uses the link position, ...

add debug browser to HelloWorld.cpp
When I run the 'HelloWorld.cpp' file, I can only see the console.
Sorry if this is a beginners question, but how can I add the visual world?

make visible only part of object
Hello,
How can one visualize only a part of an object? Let's say that I want to 'cut' an object in two based on the x-axis or overlap with another object?
Or could we do a 2D projection of a certain surface?
Is that possible?
Thanks!
Mark

How to create slider in PyBullet
How can one create a slider in PyBullet?
In other words: how to create an object with only one degree of freedom? Let's say that I want my object to freely move in the x-direction, but is restricted in the y- and z-direction. It this possible in PyBullet?
