In the virtual training room participants can use a pointer to better communicate with the other participants in the room.
For the host- the pointer is deactivated by default. After clicking on pointer button, in order to activate it, the host can now click on any location on the model in order for the other participants to view it.
For guests- Pointer is disabled by default. In order for a guest to use the pointer, the host must first allow participants pointers by clicking the "allow guest pointers" in the participants panel. That will enable the guests pointer button which can subsequently be used the same way a host can use the pointer.
Note: Each participant displays their own pointer as a dot, but the other participants view a "laser" like pointer initiating from the avatars hand.
