Multiple Realizations in CoViz
In CoViz, a feature called Multiple Realizations is available for animating collections of related files that lack an associated date or time step (download the movie here). A typical example of Multiple Realizations is a set of faces files, each representing a slightly different model from the others. In combination, this set could show, for example, the different possible positions of a fault. A simple text file associates the multiple files together and controls their appearance and animation in the CoViz Viewer. The individual files that comprise the realization are the same as any other file type that can be displayed in CoViz.
N.B. For those already familiar with Multiple Realizations, beginning with CoViz 2.0, the extension will be .real instead of .grp.
There are three components of the .real text file: Category, Option, and Type. Category is used to describe the differences between the individual files in the set. In the example above, the category could be ″fault position″ since every faces file in the set is based on a different fault position. Option is used to describe the variability in the chosen category. In our example, Option would represent the various locations of the fault at zero, ten, twenty, etc. horizontal meters from the fault′s starting position. The final concept, Type is the format of the viewable files used within the realization. In our example, the type would be faces.
Suppose we have the following three .faces files:
faultmodel_1.faces
faultmodel_2.faces
faultmodel_3.faces
The first part of the filename, faultmodel, although arbitrary, needs to be included with the type designation. The underscore and number in the filename are vital to the operation of the realization, as they indicate how the files animate. The _1 indicates that this file refers to the first option in the first category of this type. In our example this means the faces file with the fault at position zero. The _2 file is the second option, and the _3 the third. Putting all this together, the full .real file for the simple example described above would look like this:
# Starting model = fault
directory .
category "fault position"
option "adjustment: 0"
option "adjustment: 10"
option "adjustment: 20"
type faultmodel faces
category "fault f32"
When the .real file is loaded in the CoViz Viewer (through the file palette, not the Data Registry), the first file in the list will be displayed and a Realizations Dialog window will open. To animate the series of files, press the movie camera icon under the Categories section, then press Play. See the attached movie for an example of 30 different model realizations.
