There are a number of example visual programs in this directory. Each one has a brief description, which may be found by choosing the "Help on Visual Program" option in the Help menu of the Visual Program Editor. You can also access the comment by choosing "Comments" when you have selected a visual program in the Data Explorer File Selection dialog box. These examples illustrate a few ways that you can put modules together to make a visualization. There are a number of subdirectories of samples/programs. These subdirectories organize the sample visual programs by topic. So, for example, in 2D_DATA, you will find visual programs which visualize two-dimensional data. NOTES: The visual program PlotLine2 requires that the macro MakeLine_macro.net be loaded before the visual program can be opened. The visual program Bounce requires that the macro Matte_macro.net be loaded before the visual program can be opened. The visual program FlyThrough requires that the macro InterpolatePositions_Macro.net be loaded before the visual program can be opened. The visual program Factorial requires that the macro Factorial_macro.net be loaded before the visual program can be opened. All required macros can be found in this directory. To load a macro, go to the file menu and choose "Load Macro". Then select the macro. Note that you will also find script language examples for many of the modules in the directory samples/scripts. Only the example visual program ExampleSMP contains a Partition module. If you are using DX SMP, this module will divide the data to take advantage of the multiple processors, so you should use it just after import in any of your visual programs. If you are using DX, the Partition module will have no effect, and is not necessary. If you Rotate the object you are viewing while in execute-on-change mode, or navigate within the images, some of the example visual programs will use an approximatation (typically a dot-surface representation) to increase the rendering speed. This option is set using the "Rendering Options" choice in the Options menu of the Image window. You can disable the approximation by choosing "none" for button-down approximation, or alternatively you can enable the approximation for visual programs which do not use it by choosing an approximation for button-down rendering.
