Detailed Description

This is a node that contains a pointer to an PartBundle.

Like AnimBundleNode, it exists to make it easy to store PartBundles in the scene graph.

(Unlike AnimBundleNode, however, PartBundleNode has an additional function: it is also the base class of the Character node type, which adds additional functionality.)

Constructor & Destructor Documentation

PartBundleNode::PartBundleNode	(	const string &	name,
		PartBundle *	bundle
	)		`[inline]`

The PartBundle and its node should be constructed together.

Generally, the derived classes of PartBundleNode will automatically create a PartBundle of the appropriate type, and pass it up to this constructor.

Definition at line 26 of file partBundleNode.I.

PartBundleNode::PartBundleNode ( ) [inline, protected]

For internal use only.

Definition at line 38 of file partBundleNode.I.

PartBundleNode::PartBundleNode ( const PartBundleNode & copy ) [inline, protected]

Use make_copy() or copy_subgraph() to copy one of these.

This constructor does not copy the bundle pointers.

Definition at line 50 of file partBundleNode.I.

Member Function Documentation

void PartBundleNode::apply_attribs_to_vertices	(	const AccumulatedAttribs &	attribs,
		int	attrib_types,
		GeomTransformer &	transformer
	)		`[virtual]`

Applies whatever attributes are specified in the AccumulatedAttribs object (and by the attrib_types bitmask) to the vertices on this node, if appropriate.

If this node uses geom arrays like a GeomNode, the supplied GeomTransformer may be used to unify shared arrays across multiple different nodes.

This is a generalization of xform().

Reimplemented from PandaNode.

Definition at line 50 of file partBundleNode.cxx.

References Thread::get_current_thread(), PandaNode::r_mark_geom_bounds_stale(), and update_bundle().

int PartBundleNode::complete_pointers	(	TypedWritable **	p_list,
		BamReader *	manager
	)		`[virtual]`

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().

Returns the number of pointers processed.

Reimplemented from TypedWritable.

Reimplemented in Character.

Definition at line 187 of file partBundleNode.cxx.

void PartBundleNode::fillin	(	DatagramIterator &	scan,
		BamReader *	manager
	)		`[protected, virtual]`

This internal function is called by make_from_bam to read in all of the relevant data from the BamFile for the new PandaNode.

Reimplemented from PandaNode.

Reimplemented in Character.

Definition at line 208 of file partBundleNode.cxx.

References BamReader::get_file_minor_ver(), DatagramIterator::get_uint16(), and BamReader::read_pointer().

PartBundleHandle * PartBundleNode::get_bundle_handle ( int n ) const [inline]

Returns the PartBundleHandle that wraps around the actual nth PartBundle.

While the PartBundle pointer might later change due to a future flatten operation, the PartBundleHandle will not.

Definition at line 85 of file partBundleNode.I.

void PartBundleNode::steal_bundles ( PartBundleNode * other ) [protected]

Moves the PartBundles from the other node onto this one.

Definition at line 133 of file partBundleNode.cxx.

References PartBundleHandle::get_bundle(), and PartBundle::remove_node().

Referenced by Character::combine_with().

void PartBundleNode::update_bundle	(	PartBundleHandle *	old_bundle_handle,
		PartBundle *	new_bundle
	)		`[protected, virtual]`

Replaces the contents of the indicated PartBundleHandle (presumably stored within this node) with new_bundle.

Reimplemented in Character.

Definition at line 155 of file partBundleNode.cxx.

References PartBundle::add_node(), PartBundleHandle::get_bundle(), PartBundle::remove_node(), and PartBundleHandle::set_bundle().

Referenced by apply_attribs_to_vertices(), and xform().

void PartBundleNode::write_datagram	(	BamWriter *	manager,
		Datagram &	me
	)		`[virtual]`

Writes the contents of this object to the datagram for shipping out to a Bam file.

Reimplemented from PandaNode.

Reimplemented in Character.

Definition at line 169 of file partBundleNode.cxx.

References Datagram::add_uint16(), and BamWriter::write_pointer().

void PartBundleNode::xform ( const LMatrix4f & mat ) [virtual]

Transforms the contents of this PandaNode by the indicated matrix, if it means anything to do so.

For most kinds of PandaNodes, this does nothing.

Reimplemented from PandaNode.

Definition at line 75 of file partBundleNode.cxx.

References LMatrix4f::almost_equal(), PartGroup::copy_subgraph(), PartBundle::get_num_nodes(), LMatrix4f::ident_mat(), update_bundle(), and PartBundle::xform().
