[Chimera-users] question about stereo pairs

Hi Kristin,
I believe the angle may vary depending on the Chimera window size and automatically detected screen size.  You do have control via a set of interdependent stereo parameters, but not directly (i.e. as far as I know there is no way to directly specify that angle). The stereo parameters, "eye separation" etc. can be changed in the Camera tool (a tab behind the Side View), interactively in theTop View (in Side View, set "Side" to "top"), and the field of view parameter can be changed with the "set" command.

The explanation of interrelationships is described in that first link, for the "Stereo parameters" section of the Camera tool.  Sorry it is a bit involved.

For a specific angle, however, I suppose you could just save a (non-stereo) image, rotate the desired angle, say with the "turn" command, and then save another image, then abut the two images in some other program.  Not sure how to get the correct separation of the two images in that case, however.

I hope this helps,
