[chimerax-users] Placing markers using the VR wands

[Tom Goddard]

Hi Mike,

  It is place along the line extending from the cone (along the cone axis).  I haven't added a mode to place a marker exactly at the tip of the VR hand-controller cone yet because that mode won't work with a mouse (where only xy position, without z is available), and currently the VR modes just use the mouse mode user interface with no extra VR-specific features.

	Tom

First I would try this without virtual reality, just using the mouse.  That is working for me in ChimeraX from a few days ago, but I see in today's daily build it gives an error.  Are you seeing an error, or just no marker is placed?  First I would try it with mouse, then try VR.  Unfortunately the VR marker placement does not have a mode to place the marker exactly at the 3d position of the want (cone tip).  That would be useful and I've been wanting to add that.  So in VR it behaves just like with the mouse only it places the marker along the line extending from the wand (cone).

It doesn’t seem to work with “vr off” either, using the mouse. I’d like to place markers in a tomogram, either in a density, or (preferably) at a specific 3D position with the wand. Thanks,
