Hi there,
I hope you could help me with a little script. I am pretty sure, that something must exists already;-) I need to rotate around the y-axis in 2 degree steps for a total of 44 degree and at each step export a high res graphic. Rotation of the camera/view (keeping the look-at point) would be preferable compared to rotation of the object. Anything out there like this???
Thanks for your help, Tanja
Hi Tanja, In Chimera, I believe the commands move the objects, not the camera, but otherwise it can be done using the commands "perframe" (to do some things at every frame), "turn" (to rotate around Y axis) and "copy" (to save the image file).
For example, the following saves PNG files named 001.png, 002.png, ... 022.png as a structure is rotated in 2° increments about the Y axis: perframe "turn y 2; copy png file ~/Desktop/$1.png" frames 22 zero 3
See manual for explanation of command options and more examples: http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/perframe.html http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/turn.html http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/copy.html

thanks, this really was what i was looking for! btw, i saw that chimera is able to export a set of lenticular images. do you have any experience with that? some contact who can produce then such a 3d image???
have a nice we, tanja

Hi Tanja, I haven't made lenticular images personally, but others in our lab have done so. If you didn't see it already, here is documentation (prerequisites and instructions):
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/lenticular.html
As detailed in that page, you would need additional software (besides Chimera) to interlace the images, a high-res printer, the lensing material itself, and a cold laminator.

Hi Elaine,
the settings that are defined in Chimera to output a set of lenticular images work fine. However, we would like to experiment with a wider viewing angle....and I realized that increasing the number of output images decreases only the angle step size, but does not widen the viewing angle. Is there a way to influence this command line???
Thanks again, wishing you a nice day, Tanja

Hi Tanja,
The command “set fieldOfView 60” will set the horizontal field of view to 60 degrees. Typically it is around 30 degrees in normal Chimera use. You can see the value and change using menu Tools / Viewing Controls / Camera. Another parameter you may be interested in is “eye separation” in the Camera dialog. It will change the sense of depth — usually I use the cross-eye or wall-eye camera mode (also set in the Camera dialog) to preview on-screen the eye separation effect before making a lenticular image. A basic problem is not having objects that project out towards the viewer too far. That usually will not look good due to limitations of the lenticular (and other stereoscopic) technology — basically the physical image (lenticular print or screen) is not wide enough to portray an object close to the viewer’s face because projecting a line through such an object would land outside the bounds of the physical image.
