Topic Description

Hi,
Following 3dgrut project and NuRec docs I have input my 3DGS assets into Isaac Sim with python APIs to change the position and orientation of the whole 3DGS asset.
However, I am now looking to dynamically adjust the position and orientation of individual Gaussian particles during simulation. Is there a way to achieve this, perhaps through a Python API or other means?
I have attempted to reload the modified 3DGS asset to accomplish this, but the loading process is prohibitively slow. Any suggestions or guidance would be greatly appreciated.

Let me reach out to the internal team about your question

Currently we don’t support moving individual particles around.

If you want to have multiple gaussians in the scene, you can do that, and then move one of them around wrt another.

But that’s different from dynamically moving some of them.
