◆ TranslateToSG()

SGNODE * WRL2POINTSET::TranslateToSG ( SGNODE aParent)
overridevirtual

Produce a representation of the data using the intermediate scenegraph structures of the kicad_3dsg library.

Parameters
aParentis a pointer to the parent SG node.
Returns
is non-NULL on success.

Implements WRL2NODE.

◆ unlinkChildNode()

void WRL2POINTSET::unlinkChildNode ( const WRL2NODE aNode)
overridevirtual

Remove references to an owned child.

It is invoked by the child upon destruction to ensure that the parent has no invalid references.

Parameters
aNodeis the child which is being deleted.

Reimplemented from WRL2NODE.

◆ unlinkRefNode()

void WRL2POINTSET::unlinkRefNode ( const WRL2NODE aNode)
overridevirtual

Remove pointers to a referenced node.

It is invoked by the referenced node upon destruction to ensure that the referring node has no invalid references.

Parameters
aNodeis the node which is being deleted.
