Based on the presence information, a first client station presents a view of a first rendered 3D model including a visual representation of a second individual concurrently interacting with a second rendered 3D model and indicating the position and orientation of the second rendered 3D model. Based on a change in one or both of the position or orientation of the second rendered 3D model, the presence information is updated. The first client station updates the view of the first rendered 3D model to reflect the change in the position or orientation of the second rendered 3D model. ## Claims ### Claim 1 A computing platform comprising: at least one processor;
