There are two ways of drawing in MeetinVR:
3D drawing. Drawing in the thin air.
2. 2D drawing. Drawing on the surfaces such as printed notes, images, whiteboards and walls.
Note that you cannot draw on the tablet
The drawing tool is usually attached to the right side of your tablet. If you do not have one in place, you can always grab a pen from behind your right ear.
To get rid of the pen you can simply toss it and it will disappear like any other objects in our virtual space.
