I wrote a pymol plugin that produces a bunch of cgo. The images I generate have a cube drawn around them.
I've been asked if it's possible to allow the user to initially rotate the image to their heart's content and then have the plugin draw the surrounding cube. I.e., once the image is rotated, the cube will be drawn in a way that always looks good to the viewer, not at some random angle. In other words, the cube will always have the same orientation, no matter how much the image has been rotated before the cube is drawn. OK, having said the same thing 3 times, and hopefully made sense at least once, I'll say something new... I imagine this can be done easily enough. I guess I should be able to call get_view and get the current rotation matrix (elements 0-8 of the returned list) and apply this to all points that I plan to draw between when making the cube. My questions: Is this right? Do I need to do anything more than just multiply the old point by the rotation matrix? What's the easiest way to do this in Pymol or Python, or should I just code it (it's very simple after all). And, of course, is there a better way to do what I want? Thanks for any help. Don't assume I know what I'm doing, because I probably don't. So the more details, the better. Regards, Terry
