Detailed Description
A special binner used only within this package to pre-process the egg tree for the loader and group things together as appropriate.
It is used to collect similar polygons together for a Geom, as well as to group related LOD children together under a single LOD node.

Member Function Documentation
◆ get_bin_name()
|
virtual |
May be overridden in derived classes to define a name for each new bin, based on its bin number, and a sample child.
Reimplemented from EggBinMaker.
Definition at line 80 of file eggBinner.cxx.
◆ prepare_node()
|
virtual |
May be overridden in derived classes to perform some setup work as each node is encountered.
This will be called once for each node in the egg hierarchy.
Reimplemented from EggBinMaker.
Definition at line 39 of file eggBinner.cxx.
References TypedObject::is_of_type().
◆ sorts_less()
May be overridden in derived classes to create additional bins within a particular bin number, based on some arbitrary property of nodes.
This function establishes an arbitrary but fixed ordering between nodes; if two nodes do not sort to the same position, different bins are created for each one (with the same bin number on each bin).
Reimplemented from EggBinMaker.
Definition at line 92 of file eggBinner.cxx.
