assign_material_to_geom()

void MeshImporter::assign_material_to_geom	(	COLLADAFW::MaterialBinding	cmaterial,
		std::map< COLLADAFW::UniqueId, Material * > &	uid_material_map,
		Object *	ob,
		const COLLADAFW::UniqueId *	geom_uid,
		short	mat_index )

We do not know in advance which objects will share geometries. And we do not know either if the objects which share geometries come along with different materials. So we first create the objects and assign the materials to Object, then in a later cleanup we decide which materials shall be moved to the created geometries. Also see optimize_material_assignements() above.

optimize_material_assignements()

void MeshImporter::optimize_material_assignements

(

)

During import all materials have been assigned to Object. Now we iterate over the imported objects and optimize the assignments as follows:

for each imported geometry: if number of users is 1: get the user (object) move the materials from Object to Data else: determine which materials are assigned to the first user check if all other users have the same materials in the same order if the check is positive: Add the materials of the first user to the geometry adjust all other users accordingly.

write_geometry()

bool MeshImporter::write_geometry

(

const COLLADAFW::Geometry *

geom

)

Create a mesh storing a pointer in a map so it can be retrieved later by geometry UID.
