MPxComponentConverters are registered with a unique render item name. A registered MPxComponentConverter will be used to perform custom viewport 2.0 selection.
They are used to convert selection intersection data to a list of object components (MFnComponent), by matching the index buffer positions (MIntersection::index()) to valid component ids.
The same converter can be registered against different render item name, meaning that different render items can share the same component converter.
Once all of the geometry hits have been passed to the converter through calls to addIntersection(), Maya will call this method to retrieve the components corresponding to those hits. More...
