Yes Tom that is exactly right - don’t really mind how it works so long as center of view rotation works (I guess that is for Chimera 2 though). In the meantime a preference for clip planes on as you describe would be great!

Cheers,
Oliver.

Hi Oliver,

  Is the main point of your request to be able to set a clip plane on/off preference so that center-of-view rotation works?  If so the what is needed is to fix center-of-view rotation.  I made a bug report for that problem yesterday.


With clip planes enabled they still need to automatically adjust. For instance before you open the first data set they are positioned at z -1 and 1.  If they don’t adjust when you open the first data you won’t see the data.  Commands like “focus” with no arguments are documented to turn off clip planes.  If you want clip planes to remain enabled you would use “focus #0”.  We won’t add global setting that override the documented behavior of commands.  Still it probably is possible to make clip planes on a preference with the planes adjusting when the first data set is opened.  This is the way Chimera behaved 5 years ago.

Dear Tom - just tried this out and it works exactly as I would hope - this makes it much easier to navigate precisely within a structure, thank you.

One additional request on this - would it be possible to add a parameter that locks global clipping on for the session unless explicitly altered by the user?

At the moment, it seems that global clipping is off by default for a new session even if I try to save it in the camera settings, and then in “center of view” mode the cofr keeps shifting about as the clipping planes auto adjust. It would be great to have a way to set clipping planes on as the default unless explicitly altered.

Best,
Oliver.

Hi Oliver,

I added display of a cross hair (plus sign) at the center of rotation in the graphics window.  You turn it on with command

set showCofR

and turn it off with

~set showCofR

The crosshair is white on black (and dark) backgrounds and black on white (or light) backgrounds.  This will be in tonight’s daily build.
