Papervision3D filter notes

Typically when adding filters in papervision you have to use ViewportLayers and apply the filters to them, however this can become messy and tedious if you are applying filters to a large number of objects. So instead you can simply set the objects attribute useOwnContainer to true, and then apply filters directly to the object.

useOwnContainer = true;

When zooming in a great deal on an object which uses a filter or with many objects in a scene which have filters applied to them, if you do not turn the filters off during this zoom, the flash movie can have a tendency to freeze or lag the frame rate to just about zero.
