Morph Map Morph Map icon

Morph Map morphs between two related sets of volume data. The data sets must have the same grid dimensions, spacing, and numbers of points. By default, intermediate states are generated by linear interpolation. A smooth progression from one map to the other can be displayed and recorded as a movie. See also: Volume Series

There are several ways to start Morph Map, a tool in the Volume Data category (including from the Volume Viewer Tools menu).

The map files will be listed as choices if they have already been opened (from Volume Viewer or otherwise), or they can be located and opened with Browse.

Moving the Fraction slider generates the corresponding interpolated state. At a fraction of zero, the interpolated map is the same as the First map, and at a fraction of 1, it is the same as the Second map. Interpolation creates a new data set (Writable copy...) for which display parameters (threshold level/color, surface smoothing, etc.) can be adjusted in Volume Viewer to control the appearance of the morph.

Play and Record both progress from the Movie start fraction to the end fraction and back, in increments of step. Play oscillates continuously until Stop is clicked. Record progresses through a single cycle, saving an image at each step, and then raises a dialog for specifying: Close closes the Morph Map interface.
