Detailed Description

A specialization on EggBinMaker for making polysets that share the same basic rendering characteristic.

This really just defines the example functions described in the leading comment to EggBinMaker.

It makes some common assumptions about how polysets should be grouped; if these are not sufficient, you can always rederive your own further specialization of this class.

◆ setProperties()

setProperties ( int  properties)

Sets the set of properties that determines which polygons are allowed to be grouped together into a single polyset.

This is the bitwise 'or' of all the properties that matter. If this is 0, all polygons (within a given group) will be lumped into a common polyset regardless of their properties.
