VR picking distance is too large

[goddard@…]

The following bug report has been submitted:
Platform:        Windows-10-10.0.19044
ChimeraX Version: 1.6.dev202302032137 (2023-02-03 21:37:53 UTC)
Description
VR atom selection with hand controller can pick very distant atoms by accident.   The maximum picking distance is controlled by the vr command clickRange option that defaults to 5 and is documented to be in scene units (Angstroms).  But in fact it is treated as if it is meters in the room units.  I think it is good to use room units.  But the default click range should be 0.10 (10 centimeters) to avoid accidentally picking distant objects.

[Tom Goddard]

Fixed.

I've changed the definition of the vr command clickRange value so it is now in meters in the room and defaults to 0.10 (10 centimeters = 4 inches). Some current VR users who were used to the 5 meter picking range may be surprised by this new behavior if they actually use it to pick objects further away than 10 centimeters. For example, when placing a marker on a electron microscopy surface using the hand controller a user click much further than 10 centimeters away because the surface is zoomed to a large size of many meters. Then no marker will be placed. Will have to see if the 10 centimeter maximum range causes problems for some VR hand controller modes.

Elaine, could you change the vr command documentation to say that the clickRange option has units of meters in the room, and not Angstroms in the scene, with default 0.10. Also it may be worth noting in a more prominent location in VR hand controller documentation that the picking maximum range is in general 10 centimeters.

Hi- Thanks, Tom. Will it be in the daily build?
