Object Filtering (objectFilter)

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

In the Launcher, click the Plug-ins button to bring up the Plug-ins Selection dialog. Enable the plugin. Then launch VR-Forces.

1. Start vrfGui.
2. Choose Objects 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
