On Windows, you can obtain the Microsoft Visual Studio Express Edition for free. In addition you will need to download the VTK source and build it. We are assuming you already have JDK and a Java development environment such as Netbeans or Eclipse installed.

In the following sections we show you how to install and configure the VTK / Java development environment and how to use it to build a simple Java GUI-driven application. VTK comes with support for Java in the form of Java wrappers. So how do you couple VTK with Java? It’s very easy. Instead of downloading, configuring, and compiling QT (a task for multiple hours), GUI support is natively built into Java via the Swing library. As discussed previously in our article on Java multithreading, the great benefit of Java is that it comes bundled with a large API.

We are currently rewriting the software, however this time we are developing the code in Java. You can read more about capVTE here and here (the latter is the draft version but has color pictures). Developed in 2003, capVTE attempted to merge a simplified user interface with the open-source nature of VTK, while at the same time supporting new concepts such as immersed and collaborative visualization. The QT/VTK combination was the basis for our simple visualization program, capVTE.

Luckily for us, VTK ships with a built-in support for both QT and Java. But in order to develop an interactive end-user program, you’ll need to incorporate VTK within the GUI of your application. Such an approach may be sufficient for simple console-based applications.

VTK provides a simple graphical window that can be used for plotting and interacting with the data (rotation, panning, zoom, etc.). The actual data processing and plotting is performed within the VTK library. In order to add visualization to your program, you simply need to provide the algorithm to build the pipeline. Along the way, in the pipeline, various operations are applied to obtain the output of interest. The pipeline starts at one end with the source data and ends at the other end with an actor that correspond to the data’s visual representation. VTK is built on the concept of a visualization pipeline. It is the engine that does the actual work. The Visualization Toolkit is an amazing collection of C++ classes for processing and visualizing data.

For instance, you may be developing your own simulation software and would like to bundle the solver with a simple visualization output that will allow the user to study the results in real-time. However, sometimes these options may not be quite adequate. The free alternatives include VisIt from Livermore, and Paraview from Kitware, Inc., the creators of the Visualization Toolkit, VTK. Of the commercial kind, a popular program is Tecplot.

There are both commercial and open-source solutions for performing data visualization. We can easily visualize the plume by plotting the isosurface of some critical minimum value. But we may only be interested in the shape of the plume. The simulation grid may consist of millions of nodes and on each node we will have a value corresponding to the local plume density. For example, consider a CAD/flow simulation of a rocket plume. Scientific visualization is the art of converting these numbers into a graphical format that can be understood and aid us in obtaining a new understanding about some physical problem. These numbers correspond to the results at various spatial locations. By itself, such a result is rather meaningless.

The typical output from a simulation code is a large file full of numbers. We will use The Visualization Toolkit ( VTK) for the actual data analysis and rendering and Java Swing libraries for a simple GUI that will allow us to modify the plotted output. In this post we’ll show you how to develop a simple Java application for visualizing scientific data.
