Environmental model for collision check

[sollynoay]

Very impressive work! Previously we were also trying to do collision detection with an environmental model and a virtual robot. We found this is not very easy since the point cloud from Quest cannot be accessed because of privacy problems. The feasible way is to pre-scan the environment with HMD and use that information for collision detection. I am wondering how the prescanned environment information is loaded in your project. There are some packages and which one are you using? Besides, it seems only Quest3 can scan a more precise mesh model. We are using Quest Pro, it seems it does not have an environment scan function and we need to set up the model of the environment manually.

Hi, thanks for your interest! We use scene API to access pre scaned environment from Quest. These links may be helpful:

   To check collision between robot and object in the scene, we set each collision to trigger mode and add callback functions to collision: here
