Re: Training a Humanoid with the OpenAI baselines algorithms?

Hi, You should try to train the HumanoidBulletEnv-v0. This is the one that constitutes a proper gym env whereas the other is deprecated now. I will soon make a pull request on how to easily train all envs with tensorforce. So I will check if I can easily give an example on how to train it with basel...

Re: How to reset simulation

Could you post that code, benelot? I think it would be very useful! Ok, I just looked into my code and tried to get a quick overview of how it is done: First reset the multibody base position: if (mMultiBody) { mMultiBody->setBasePos(position); } Then for each MultiBodyLinkCollider, you do: btTrans...

Re: Forum not using SSL

Hi! The forum has not been updated for a long time and is utterly outdated. This is mainly due a long due php update which can not be performed on the server for now (do not ask me for the details, that is all I remember the maintainer saying). Since the wiki is going to be moved to github, I do not...

Re: CPU multithreading is working!

Check out the multithreaded demo in the example browser:
You should see easily what is necessary to set it up:

Re: btConeTwistConstraint for single body

No, you do not need a second rigid body, you can attach the constraint to the world frame. Look at the constraints demo in the bullet example browser. There it should show exactly what you want to do.

Re: Set Color of Individual Rigid Bodies in ExampleBrowser

You can not set the color of the individual objects in the example browser. This is not part of the API. If you need this, you have to move out of the example browser. The example browser only shows what you can do with the physics engine. It has minimal graphics to make things visual.

Re: How to make "graphical" bullet

Hello, Bullet does not know anything about visualizing, so therefore you need a graphics engine to do this for you. Just choose one that you find most appropriate for your application and learn how it is used. Nice engines at hand are Ogre3D, Irrlicht or Panda3D. Just check what matches your ideas m...

Re: Making a faster rayTest?

Maybe somebody could contribute the faster version of ClosestRayResultCallback which does not calculate all other ray results?

Re: Just Getting Started, Would Like Advice on Tools

Ok, yeah with your custom c it should be doable. Just can make your c tunable and see how far you can go. I heard that Irrlicht is also pretty nice with Bullet. BulletSharp might be ok with Unitt, but it is a port of Bullet and I have no idea how well supported this is whereas Bullet here is well su...

Re: [SOLVED] Objects existing in 2 worlds at same time?

Your portals look great btw! At some point you maybe can showcase it in the other bullet subforum, which is made for this. Do you have a video of your first person character passing through the portals?

If anybody of you has a complete OpenGL implementation of the BulletDebugDrawer, just post it here and we can add it to the wiki for future reference.

Re: [SOLVED] Objects existing in 2 worlds at same time?

What should your world changer do? I think all you need is removing from one world and adding to another world?

Re: Serialization of Softbodies

Hi,

The serialization demo is in the old_demos branch here:

Maybe this helps you. If you are interested to port this into the Example Browser, let me know!

Re: [pybullet] DIRECT and GUI mode issue

Can not confirm this issue. I am using pybullet since day one and I usually made the mistakes by compiling a messed up version (not up-to-date etc.), pybullet was always working fine.

Re: Making a faster rayTest?

If you log a bug, can you build a simple example browser example (based on BasicExample or the raytest one) and maybe add some timings with btClock to it? By that you speed up the debugging as it can then be used as a unit test for debugging. Also it shows for everyone that the bug actually is there...
