All function have to be followed by parentheses. The equations are evaluated automatically when a visualization method is applied. A blue progress bar indicates the advance of the conversion progress. Unfortunately Java does not support local file access within a network. 3 Visulization 3.1 General features A visualization method is invoked by pressing the according button.
Some techniques show a dialog box to allow changes of some parameter of the visualization technique.
Each window can be closed separately by using the system menu or hotkey provided by your operating system. The magnitude of each vector is mapped to a gray scale value, where the color white indicates high velocity, whereas low velocities are mapped to black. A linear mapping is used, thus statistical outliers can produce low significant images. The mapping uses the minimum and maximum speed occurring in the vector field. The arrows are placed on a regular grid with adjustable spacing in x and y direction.
