Detailed Description

NodePath is the fundamental system for disambiguating instances, and also provides a higher-level interface for manipulating the scene graph.

A NodePath is a list of connected nodes from the root of the graph to any sub-node. Each NodePath therefore uniquely describes one instance of a node.

NodePaths themselves are lightweight objects that may easily be copied and passed by value. Their data is stored as a series of NodePathComponents that are stored on the nodes. Holding a NodePath will keep a reference count to all the nodes in the path. However, if any node in the path is removed or reparented (perhaps through a different NodePath), the NodePath will automatically be updated to reflect the changes.

Constructor & Destructor Documentation

NodePath() [1/4]

NodePath::NodePath ( )

inline

This constructs an empty NodePath with no nodes.

Definition at line 18 of file nodePath.I.

Referenced by set_billboard_axis(), set_billboard_point_eye(), and set_billboard_point_world().

NodePath() [2/4]

NodePath::NodePath ( const std::string &  top_node_name, Thread *  current_thread = Thread::get_current_thread()  )

inlineexplicit

This constructs a new NodePath with a single node.

An ordinary, unattached PandaNode is created with the indicated name.

Definition at line 29 of file nodePath.I.

References Thread::get_pipeline_stage.

NodePath() [3/4]

NodePath::NodePath ( PandaNode *  node, Thread *  current_thread = Thread::get_current_thread()  )

inlineexplicit

This constructs a NodePath for the indicated node.

If the node does not have any parents, this creates a singleton NodePath; otherwise, it automatically finds the path from the node to the root. If the node has multiple paths to the root, one path is chosen arbitrarily and a warning message is printed (but see also NodePath::any_path(), below).

Definition at line 46 of file nodePath.I.

References Thread::get_pipeline_stage, and node().

NodePath() [4/4]

NodePath::NodePath ( const NodePath &  parent, PandaNode *  child_node, Thread *  current_thread = Thread::get_current_thread()  )

explicit

Constructs a NodePath with the indicated parent NodePath and child node; the child node must be a stashed or unstashed child of the parent.

Definition at line 95 of file nodePath.cxx.

Member Function Documentation

add_hash()

size_t NodePath::add_hash ( size_t  hash ) const

inline

Adds the NodePath into the running hash.

This is intended to be used by lower-level code that computes a hash for each NodePath. It modifies the hash value passed in by a unique adjustment for each NodePath, and returns the modified hash.

This is similar to the unique integer returned by get_key(), but it is not guaranteed to remain unique beyond the lifetime of this particular NodePath. Once this NodePath destructs, a different NodePath may be created which shares the same hash value.

Definition at line 264 of file nodePath.I.

References pointer_hash::add_hash().

adjust_all_priorities()

void NodePath::adjust_all_priorities ( int  adjustment )

inline

Adds the indicated adjustment amount (which may be negative) to the priority for all transitions on the referenced node, and for all nodes in the subgraph below.

This can be used to force these nodes not to be overridden by a high-level state change above. If the priority would drop below zero, it is set to zero.

Definition at line 1776 of file nodePath.I.

any_path()

NodePath NodePath::any_path ( PandaNode *  node, Thread *  current_thread = Thread::get_current_thread()  )

inlinestatic

Returns a new NodePath that represents any arbitrary path from the root to the indicated node.

This is the same thing that would be returned by NodePath(node), except that no warning is issued if the path is ambiguous.

Definition at line 62 of file nodePath.I.

apply_texture_colors()

void NodePath::apply_texture_colors

(

)

Removes textures from Geoms at this node and below by applying the texture colors to the vertices.

This is primarily useful to simplify a low-LOD model. The texture colors are replaced by flat colors that approximate the original textures.

Only the bottommost texture on each Geom is used (if there is more than one), and it is applied as if it were M_modulate, and WM_repeat, regardless of its actual settings. If the texture has a simple_ram_image, this may be used if the main image isn't resident.

After this call, there will be no texturing specified at this level and below. Of course, there might still be texturing inherited from above.

Definition at line 5573 of file nodePath.cxx.

attach_new_node() [1/2]

NodePath NodePath::attach_new_node	(	PandaNode *	node,
		int	sort = 0,
		Thread *	current_thread = Thread::get_current_thread()
	)		const

Attaches a new node, with or without existing parents, to the scene graph below the referenced node of this NodePath.

This is the preferred way to add nodes to the graph.

If the node was already a child of the parent, this returns a NodePath to the existing child.

This does *not* automatically extend the current NodePath to reflect the attachment; however, a NodePath that does reflect this extension is returned.

attach_new_node() [2/2]

NodePath NodePath::attach_new_node ( const std::string &  name, int  sort = 0, Thread *  current_thread = Thread::get_current_thread()  ) const

inline

Creates an ordinary PandaNode and attaches it below the current NodePath, returning a new NodePath that references it.

Definition at line 389 of file nodePath.I.

calc_tight_bounds()

bool NodePath::calc_tight_bounds	(	LPoint3 &	min_point,
		LPoint3 &	max_point,
		const NodePath &	other = NodePath(),
		Thread *	current_thread = Thread::get_current_thread()
	)		const

Calculates the minimum and maximum vertices of all Geoms at this NodePath's bottom node and below.

This is a tight bounding box; it will generally be tighter than the bounding volume returned by get_bounds() (but it is more expensive to compute).

The bounding box is computed relative to the parent node's coordinate system by default. You can optionally specify a different NodePath to compute the bounds relative to. Note that the box is always axis-aligned against the given NodePath's coordinate system, so you might get a differently sized box depending on which node you pass.

The return value is true if any points are within the bounding volume, or false if none are.

clear()

void NodePath::clear ( )

inline

Sets this NodePath to the empty NodePath.

It will no longer point to any node.

Definition at line 119 of file nodePath.I.

clear_antialias()

void NodePath::clear_antialias

(

)

Completely removes any antialias setting that may have been set on this node via set_antialias().

Definition at line 4959 of file nodePath.cxx.

clear_attrib()

void NodePath::clear_attrib ( TypeHandle  type )

inline

Removes the render attribute of the given type from this node.

This node, and the subgraph below, will now inherit the indicated render attribute from the nodes above this one.

Definition at line 480 of file nodePath.I.

clear_audio_volume()

void NodePath::clear_audio_volume

(

)

Completely removes any audio volume from the referenced node.

detach_node()

void NodePath::detach_node

(

Thread *

Disconnects the referenced node from its parent, but does not immediately delete it.

The NodePath retains a pointer to the node, and becomes a singleton NodePath.

This should be called to detach a node from the scene graph, with the option of reattaching it later to the same parent or to a different parent.

In practice, the only difference between remove_node() and detach_node() is that remove_node() also resets the NodePath to empty, which will cause the node to be deleted immediately if there are no other references. On the other hand, detach_node() leaves the NodePath referencing the node, which will keep at least one reference to the node for as long as the NodePath exists.

Converts the NodePath object into a single stream of data using a BamWriter, and returns that data as a string string.

This method is used by __reduce__ to handle streaming of NodePaths to a pickle file.

encode_to_bam_stream() [2/2]

bool NodePath::encode_to_bam_stream	(	vector_uchar &	data,
		BamWriter *	writer = nullptr
	)		const

Converts the NodePath object into a single stream of data using a BamWriter, and stores that data in the indicated string.

Returns true on success, false on failure.

If the BamWriter is NULL, this behaves the same way as NodePath::write_bam_stream() and PandaNode::encode_to_bam_stream(), in the sense that it only writes this node and all nodes below it.

However, if the BamWriter is not NULL, it behaves very differently. In this case, it encodes the *entire graph* of all nodes connected to the NodePath, including all parent nodes and siblings. This is necessary for correct streaming of related NodePaths and restoration of instances, etc., but it does mean you must detach() a node before writing it if you want to limit the nodes that get written.

This method is used by __reduce__ to handle streaming of NodePaths to a pickle file. The BamWriter case is used by the direct.stdpy.pickle module, while the saner, non-BamWriter case is used when the standard pickle module calls this function.

flatten_light()

int NodePath::flatten_light

(

)

Analyzes the geometry below this node and reports the number of vertices, triangles, etc.

This is the same information reported by the bam-info program. Lightly flattens out the hierarchy below this node by applying transforms, colors, and texture matrices from the nodes onto the vertices, but does not remove any nodes.

This can result in improved rendering performance because there will be fewer transforms in the resulting scene graph, but the number of nodes will remain the same.

In particular, any NodePaths that reference nodes within this hierarchy will not be damaged. However, since this operation will remove transforms from the scene graph, it may be dangerous to apply to nodes where you expect to dynamically modify the transform, or where you expect the geometry to remain in a particular local coordinate system.

The return value is always 0, since flatten_light does not remove any nodes.

Definition at line 5495 of file nodePath.cxx.

flatten_medium()

int NodePath::flatten_medium

(

)

A more thorough flattening than flatten_light(), this first applies all the transforms, colors, and texture matrices from the nodes onto the vertices, and then removes unneeded grouping nodes–nodes that have exactly one child, for instance, but have no special properties in themselves.

This results in improved performance over flatten_light() because the number of nodes in the scene graph is reduced.

The return value is the number of nodes removed.

Definition at line 5515 of file nodePath.cxx.

flatten_strong()

int NodePath::flatten_strong

(

)

The strongest possible flattening.

This first applies all of the transforms to the vertices, as in flatten_medium(), but then it will combine sibling nodes together when possible, in addition to removing unnecessary parent-child nodes. This can result in substantially fewer nodes, but any nicely-grouped hierachical bounding volumes may be lost.

It is generally a good idea to apply this kind of flattening only to nodes that will be culled largely as a single unit, like a car. Applying this to an entire scene may result in overall poorer performance because of less- effective culling.

instance_to()

Adds the referenced node of the NodePath as a child of the referenced node of the indicated other NodePath.

Any other parent-child relations of the node are unchanged; in particular, the node is not removed from its existing parent, if any.

If the node already had an existing parent, this method will create a new instance of the node within the scene graph.

This does not change the NodePath itself, but does return a new NodePath that reflects the new instance node.

If the destination NodePath is empty, this creates a new instance which is not yet parented to any node. A new instance of this sort cannot easily be differentiated from other similar instances, but it is nevertheless a different instance and it will return a different get_id() value.

If the referenced node is already a child of the indicated NodePath, returns that already-existing instance, unstashing it first if necessary.

remove_node()

void NodePath::remove_node

(

Thread *

current_thread = Thread::get_current_thread()

Disconnects the referenced node from the scene graph.

This will also delete the node if there are no other pointers to it.

Normally, this should be called only when you are really done with the node. If you want to remove a node from the scene graph but keep it around for later, you should probably use detach_node() instead.

In practice, the only difference between remove_node() and detach_node() is that remove_node() also resets the NodePath to empty, which will cause the node to be deleted immediately if there are no other references. On the other hand, detach_node() leaves the NodePath referencing the node, which will keep at least one reference to the node for as long as the NodePath exists.

set_bin()

void NodePath::set_bin	(	const std::string &	bin_name,

Assigns the geometry at this level and below to the named rendering bin.

It is the user's responsibility to ensure that such a bin already exists, either via the cull-bin Configrc variable, or by explicitly creating a GeomBin of the appropriate type at runtime.

There are two default bins created when Panda is started: "default" and "fixed". Normally, all geometry is assigned to "default" unless specified otherwise. This bin renders opaque geometry in state-sorted order, followed by transparent geometry sorted back-to-front. If any geometry is assigned to "fixed", this will be rendered following all the geometry in "default", in the order specified by draw_order for each piece of geometry so assigned.

The draw_order parameter is meaningful only for GeomBinFixed type bins, e.g. "fixed". Other kinds of bins ignore it.

void NodePath::set_clip_plane_off

(

int

priority = 0

)

Sets the geometry at this level and below to render using no clip_planes at all.

This is different from not specifying a clip_plane; rather, this specifically contradicts set_clip_plane() at a higher node level (or, with a priority, overrides a set_clip_plane() at a lower level).

If no clip_planes are in effect on a particular piece of geometry, that geometry is rendered without being clipped (other than by the viewing frustum).

set_clip_plane_off() [2/2]

void NodePath::set_clip_plane_off	(	const NodePath &	clip_plane,

set_collide_mask()

void NodePath::set_collide_mask ( CollideMask  new_mask, CollideMask  bits_to_change = CollideMask::all_on(), TypeHandle  node_type = TypeHandle::none()  )

inline

Recursively applies the indicated CollideMask to the into_collide_masks for all nodes at this level and below.

If node_type is not TypeHandle::none(), then only nodes matching (or inheriting from) the indicated PandaNode subclass are modified.

The default is to change all bits, but if bits_to_change is not all bits on, then only the bits that are set in bits_to_change are modified, allowing this call to change only a subset of the bits in the subgraph.

set_color_scale_off()

void NodePath::set_color_scale_off

(

int

priority = 0

Disables any color scale attribute inherited from above.

This is not the same thing as clear_color_scale(), which undoes any previous set_color_scale() operation on this node; rather, this actively disables any set_color_scale() that might be inherited from a parent node. This also disables set_alpha_scale() at the same time.

It is legal to specify a new color scale on the same node with a subsequent call to set_color_scale() or set_alpha_scale(); this new scale will apply to lower geometry.

set_compass()

void NodePath::set_compass

set_depth_offset()

void NodePath::set_depth_offset	(	int	bias,
		int	priority = 0
	)

This instructs the graphics driver to apply an offset or bias to the generated depth values for rendered polygons, before they are written to the depth buffer.

This can be used to shift polygons forward slightly, to resolve depth conflicts, or self-shadowing artifacts on thin objects. The bias is always an integer number, and each integer increment represents the smallest possible increment in Z that is sufficient to completely resolve two coplanar polygons. Positive numbers are closer towards the camera.

set_max_search_depth()

void NodePath::set_max_search_depth ( int  max_search_depth )

inlinestatic

Certain operations, such as find() or find_all_matches(), require a traversal of the scene graph to search for the target node or nodes.

This traversal does not attempt to detect cycles, so an arbitrary cap is set on the depth of the traversal as a poor man's cycle detection, in the event that a cycle has inadvertently been introduced into the scene graph.

There may be other reasons you'd want to truncate a search before the bottom of the scene graph has been reached. In any event, this function sets the limit on the number of levels that a traversal will continue, and hence the maximum length of a path that may be returned by a traversal.

This is a static method, and so changing this parameter affects all of the NodePaths in the universe.

Member Data Documentation

get_ancestor

NodePath NodePath::get_ancestor

Returns the nth ancestor of the path, where 0 is the NodePath itself and get_num_nodes() - 1 is get_top().

This requires iterating through the path.

Also see get_node(), which returns the same thing as a PandaNode pointer, not a NodePath.

Definition at line 209 of file nodePath.h.

get_children

NodePathCollection NodePath::get_children

Returns the set of all child nodes of the referenced node.

Definition at line 235 of file nodePath.h.

get_error_type

NodePath::ErrorType NodePath::get_error_type

inline

If is_empty() is true, this returns a code that represents the reason why the NodePath is empty.

Definition at line 213 of file nodePath.h.

Referenced by MeshDrawer::begin(), MeshDrawer::geometry(), and MeshDrawer::link_segment().

get_name

std::string NodePath::get_name

inline

Returns the name of the referenced node.

Definition at line 946 of file nodePath.h.

Referenced by CConstrainPosInterval::priv_step(), CConstrainHprInterval::priv_step(), and CConstrainPosHprInterval::priv_step().

get_net_tag

std::string NodePath::get_net_tag

inline

Returns the tag value that has been defined on this node, or the nearest ancestor node, for the indicated key.

If no value has been defined for the indicated key on any ancestor node, returns the empty string. See also get_tag().

Definition at line 923 of file nodePath.h.

get_node

PandaNode * NodePath::get_node

Returns the nth node of the path, where 0 is the referenced (bottom) node and get_num_nodes() - 1 is the top node.

This requires iterating through the path.

Also see node(), which is a convenience function to return the same thing as get_node(0) (since the bottom node is the most important node in the NodePath, and is the one most frequently referenced).

Note that this function returns the same thing as get_ancestor(index).node().

Definition at line 206 of file nodePath.h.

get_num_nodes

int NodePath::get_num_nodes

Returns the number of nodes in the path.

Definition at line 206 of file nodePath.h.

get_parent

NodePath NodePath::get_parent

inline

Returns the NodePath to the parent of the referenced node: that is, this NodePath, shortened by one node.

The parent of a singleton NodePath is defined to be the empty NodePath.

Definition at line 244 of file nodePath.h.

Referenced by find_net_tag(), reverse_ls(), and MultitexReducer::scan().

get_sort

int NodePath::get_sort

Returns the sort value of the referenced node within its parent; that is, the sort number passed on the last reparenting operation for this node.

This will control the position of the node within its parent's list of children.

Definition at line 245 of file nodePath.h.

get_stashed_children

NodePathCollection NodePath::get_stashed_children

Returns the set of all child nodes of the referenced node that have been stashed.

These children are not normally visible on the node, and do not appear in the list returned by get_children().

Definition at line 236 of file nodePath.h.

has_net_tag

bool NodePath::has_net_tag

inline

Returns true if the indicated tag value has been defined on this node or on any ancestor node, or false otherwise.

See also has_tag().

Definition at line 923 of file nodePath.h.

has_parent

bool NodePath::has_parent

inline

Returns true if the referenced node has a parent; i.e.

the NodePath chain contains at least two nodes.

Definition at line 244 of file nodePath.h.

Referenced by reverse_ls().

set_name

void NodePath::set_name

inline

Changes the name of the referenced node.

Definition at line 946 of file nodePath.h.
