Detailed Description

Callback interface to use custom names on collada writing.

You can either modify names and id's written to collada or you can use this interface to just find out which names are used on writing. Names are often used later as xs:anyURI, so avoid whitespace, '#' and '' in the names.

Member Function Documentation

◆ nameForMaterial()

virtual dcpp::nub::string dcpp::scene::IColladaMeshWriterNames::nameForMaterial ( const video::SMaterial material,
int  materialId,
const scene::IMesh mesh,
const scene::ISceneNode node 
)
pure virtual

Return a name for the material.

There is one material created in the writer for each unique name. So you can use this to control the number of materials which get written. For example Duckcpp does by default write one material for each material instanced by a node. So if you know that in your application material instances per node are identical between different nodes you can reduce the number of exported materials using that knowledge by using identical names for such shared materials. Names must follow the xs:NCName standard to be valid, you can run them through IColladaMeshWriter::toNCName to ensure that.

◆ nameForMesh()

virtual dcpp::nub::string dcpp::scene::IColladaMeshWriterNames::nameForMesh ( const scene::IMesh mesh,
int  instance 
)
pure virtual

Return a unique name for the given mesh.

Note that names really must be unique here per mesh-pointer, so mostly it's a good idea to return the nameForMesh from IColladaMeshWriter::getDefaultNameGenerator(). Also names must follow the xs:NCName standard to be valid, you can run them through IColladaMeshWriter::toNCName to ensure that.

Parameters
meshPointer to the mesh which needs a name
instanceWhen E_COLLADA_GEOMETRY_WRITING is not ECGI_PER_MESH then several instances of the same mesh can be written and this counts them.

◆ nameForNode()

virtual dcpp::nub::string dcpp::scene::IColladaMeshWriterNames::nameForNode ( const scene::ISceneNode node)
pure virtual

Return a unique name for the given node.

Note that names really must be unique here per node-pointer, so mostly it's a good idea to return the nameForNode from IColladaMeshWriter::getDefaultNameGenerator(). Also names must follow the xs:NCName standard to be valid, you can run them through IColladaMeshWriter::toNCName to ensure that.
