Start  vish. Some gui should come up.

Built-In Demos

Then start

vish +Analytic.vis


vish +VolumeRender.vis

and there should be something on the screen.

 Data-Based Demos


make mkdata

to create data files, then do

vish +TimeDependentScalar.vis

and see something more.

 Building Visualization Networks

Vish internally makes use of the concept of a visualization pipeline. Its elements are objects with inputs and outputs that process data. Objects with output only are called Sources, objects with inputs are called Sinks, all other objects processing data from input to output are called Filters. Different objects are connected to each other via their inputs and outputs, thereby forming a network of objects. This network can be stored in a Vish Script, which are the .vis files used in the demos above. These Vish Scripts are text files that can be edited manually, but for complex networks this becomes tedious.

The qVish Network GUI exposes these objects and their relationships visually and allows to introduce new networks and changing object parameters.
