Maybe the morph map command could work... Start a recording and Morph between two maps, one with dust hidden and the other in its natural state. -Jason Quoting Thomas Goddard <goddard@cgl.ucsf.edu>:
Hi Matt,
I assume you mean you want the "dust" to gradually fade out instead of disappear all of a sudden. I see 3 possible approaches.
Most practical: open the two copies of the density map and make two identical surfaces, hide dust on one of them, then fade the other one by making it gradually more transparent (surftransparency command). Not sure if this will look good or if the non-dust where the transparent and non-transparent surface coincide will look weird.
General solution requiring new code. Would be neat if the Chimera movie command could do cross-fades between two successive frames. Basically you would show the surface with dust, then use "movie fade frames 25", then the next command would hide the dust. The movie command would simply take the image from before the fade command and the frame drawn immediately after and blend them linearly for a specified number images. Would be not too hard to implement and would enable doing all kinds of cross-fades.
Specific solution requiring new code. The current hide dust turns of display of the surface triangles making up the dust. A modified version of that could instead change the color transparency of the dust. There is no command for hide dust (just a dialog) and this new command would probably be an option to the "sop" (surface operation) command.
I'm interested in implementing both of the above coding solutions but have many other things to work on. I'll add those ideas to the Chimera request list.

Hi,
I was trying to generate an animation transition using the HIDE DUST feature. Any suggestions on how to do it (e.g., chimera command, python, etc)?
thanks, Matt
