virtual bool cleanup()
Cleans up modeling errors in whatever context this makes sense.
void register_type(TypeHandle &type_handle, const std::string &name)
This inline function is just a convenient way to call TypeRegistry::register_type(),...
A base class for nodes in the hierarchy that are not leaf nodes.
A base class for any of a number of kinds of geometry primitives: polygons, point lights,...
TypeHandle is the identifier used to differentiate C++ class types.
