Morph Map Morph Map icon

Morph Map morphs between two related sets of volume data (maps). The data sets should have the same grids: dimensions, spacing, and numbers of points. Note the command vop resample can be used to make a copy of one map that has the same grid as another. By default, morphing intermediates are generated by linear interpolation. A smooth progression from one map to the other can be displayed and recorded as a movie.

There are several ways to start Morph Map, a tool in the Volume Data category (including from the Volume Viewer Tools menu). It is also implemented as the command vop morph.

The First map and Second map should be chosen from the adjacent lists of open volume data sets. If the maps of interest are not already open, the Browse... buttons can be used to locate and open them.

Moving the Fraction slider generates the corresponding interpolated state. The morph is opened as new volume data set, and its display settings (threshold level/color, surface smoothing, etc.) can be adjusted in Volume Viewer. At a fraction of 0.0, the interpolated map is the same as the First map, and at a fraction of 1.0, it is the same as the Second map.

Clicking Options reveals additional settings that can be hidden again by clicking the small button on the right.

Play oscillates playback continuously until Stop is clicked. Record opens a dialog for recording a movie. Close closes the Morph Map interface, and Help opens this manual page in a browser window.

Recording a Movie

Clicking the Record button in Morph Map opens a dialog with settings for recording a movie:

Advanced Options: Clicking Record plays the morph from start to end, saving an image at each step, and encodes the resulting images into a movie file.

Close dismisses the dialog without initiating recording. Image Tips shows the tips on preparing images, and Help opens this manual page in a browser window.
