Usage:
reset list

Reset restores models to a default position or one previously saved with savepos. See the video mini-example. Positions can also be restored from the Rapid Access interface. See also: fly, play, window, matrixset, scene, movie-related commands

A view_name is specified when a position is saved with savepos. A position includes:

If view_name contains spaces, it must be enclosed in single or double quotation marks. If no view_name is given, the name default is used. Unless changed with savepos, the default position is one in which the models have not been rotated or translated.

Saved positions are included in saved Chimera sessions, and a position named session-start is created automatically when a session is restored.

Reset restores the named position over the specified number of image update frames (default 1). For frames > 1, a path from the current position to the named position is generated by interpolation (details...). Whereas reset interpolation considers only a pair of positions at a time (start and end), the related command fly can generate a smooth interpolated path over a series of multiple saved positions.

Depending on the current and named positions, the camera viewpoint and the transformation of each model could change. The holdSteady option allows keeping the viewpoint fixed on a specified model while moving other models to their transformations relative to that model in the named position. The movement can apply to all other models (default) or only those specified with the moveModels keyword.

Models may have been closed or opened since the position was saved. How these situations are handled (assuming no holdSteady restriction):

Reset list lists the names of all saved positions in the status line and Reply Log.

Interpolation details. All models with the same relative transformation (rotation and translation) between the initial and final positions are grouped together as a rigid unit. The center of the bounding sphere of the group will move along a straight line between the initial and final positions, while the group rotates from the initial orientation to the final orientation about a fixed axis (and that center) at a constant angular rate.
