Object Filtering

The Object Filter example demonstrates the following:

• Create a plugin to the GUI
• Create a sub-menu for an existing menu
• Add menu items to the sub-menu
• Send element attribute change requests to visualizers
• Instancing in the myDe member variable your own class
• Creating selection filters

The Object Filer example will demonstrate how to show or hide an object based on filter criteria. A few filters are defined for the demo, however, more filters may be added

Usage

Since this example is loaded as a plugin Select Settings, Plugins... and on the Plugins Editor page, use the combo box at the top of the page to select the plug-in. Then enable the Load Plugin checkbox for the objectDemo example and re-start VR-Forces.

1. Start vrfGui.
2. Choose Entities Menu
3. Select the Visibility sub-menu
4. Choose a filter to hide objects
5. Objects that match the criteria of the filter will be hidden. Due to the nature of the example, newly created objects that meet the condition of the filter might be seen momentarily before being hidden

Classes

DtObjectFilterManager	The manager used to maintain filters for hiding objects.
DtDestroyedFilter	A filter created to hide all destroyed objects.
