public class NetVis

extends javax.swing.JComponent

Class for visualizing net data. Generates a basic 2d-visualization of a graph (knots and edges), and uses this visualization as texture for a polygon in 3d. Then, additional information is visualized using cylinders based on this polygon and extending in z-direction.
