Run ViewDemo with the imaging.skm script file to illustrate the use of some of them. The height of the surface at each point is determined by the local value of the dependent variable. Run ViewDemo with the surface.skm script file to show how to construct a surface from two-dimensional data in IRIS Explorer. Run ViewDemo with the simple.skm script file to illustrate the calculation of an isosurface using the IsosurfaceLat module. Datasets which have a magnitude and direction at each coordinate are referred to as vector-based .
Some examples are flow fields, velocity fields forces and other gradient data.
The magnitude and direction of the field at the location is used to determine the size and orientation of the glyph. In IRIS Explorer, the VectorDisplay module can be used to generate this type of visualization. Run ViewDemo with the 3dvectors.skm script file to see how it works. The particles are then moved through the dataset, under the influence of the local value of the field, and the shape of their trajectories contains useful information about the dataset. The NAGAdvectSimple and NAGAdvectAnimate modules are used to generate particle tracing from vector-based data.
