Get contact buffer for batch simulation

Hi,

I am using the IsaacGym to build a robot manipulation environment.

I was wondering that is it possible to get the contact buffer, i.e. isaacgym.gymapi.RigidContact using the Tensor API, like what can be done in the standard API get_env_rigid_contacts. Current the acquire_net_contact_force_tensor can only provide net force.

If the tensor-based pipeline does not support reading full contact information, is there any alternatives to know whether two actors are in contact with each other?

Appreciate your help. Thank you!

Hi, we currently only support tensor APIs that collect all contact forces on bodies ( acquire_net_contact_force_tensor ) or you can add force sensors to certain bodies with create_force_sensor . We will be working on a more fine-grained collision detection API that will eventually allow you to retrieve collisions between specific bodies or objects.
