[Chimera-users] reset/stereo

[Elaine Meng]

Hi Matt,
My understanding is that a "position" (what is saved with savepos and restored with reset) includes only the following, and not any stereo parameters:
the transformations of models (their rotations and translations relative to input coordinates)
the overall scale
clipping plane status, locations, and orientations
the center of rotation method
Thus the question of how stereo parameters would be interpolated is moot, since they are not even saved. This  understanding is based on explanations from the other staff and my own experiments, but perhaps the programming members of the team will have more detailed insights. Also, it may be possible to better integrate stereo parameters with position- or keyframe-saving in the future, so it is good that you are bringing up these issues.
Best,
Elaine
