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::NodePath ( ) [inline]
NodePath::NodePath ( const string &  top_node_name,
Thread current_thread = Thread::get_current_thread() 
) [inline]

This constructs a new NodePath with a single node.

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

Definition at line 36 of file nodePath.I.

References Thread::get_pipeline_stage().

NodePath::NodePath ( PandaNode node,
Thread current_thread = Thread::get_current_thread() 
) [inline]

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 57 of file nodePath.I.

References Thread::get_pipeline_stage().

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

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

Member Function Documentation

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 290 of file nodePath.I.

Referenced by LightAttrib::get_hash_impl(), and ClipPlaneAttrib::get_hash_impl().

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.

References is_empty(), and node().

NodePath NodePath::any_path ( PandaNode node,
Thread current_thread = Thread::get_current_thread() 
) [inline, static]

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.

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.

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.

bool NodePath::calc_tight_bounds ( LPoint3 min_point,

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

NodePath NodePath::decode_from_bam_stream ( const string &  data,

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.

bool NodePath::encode_to_bam_stream ( string &  data,
BamWriter writer = NULL 
) 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.

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 6787 of file nodePath.cxx.

References SceneGraphReducer::apply_attribs(), is_empty(), and node().

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.

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.

This should not normally need to be called, since the bounding volumes are supposed to be recomputed automatically when necessary.

LVector3 NodePath::get_pos_delta ( const NodePath other) const

Returns the delta vector from this node's position in the previous frame (according to set_prev_transform(), typically set via the use of set_fluid_pos()) and its position in the current frame, as seen in the indicated node's coordinate space.

This is the vector used to determine collisions. Generally, if the node was last repositioned via set_pos(), the delta will be zero; if it was adjusted via set_fluid_pos(), the delta will represent the change from the previous frame's position.

NodePath NodePath::instance_to ( const NodePath other,

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.

Walks through the scene graph beginning at the bottom node, and internally adjusts any GeomVertexFormats for optimal rendering on the indicated GSG.

If this step is not done prior to rendering, the formats will be optimized at render time instead, for a small cost.

It is not normally necessary to do this on a model loaded directly from disk, since the loader will do this by default.

Walks through the scene graph beginning at the bottom node, and does whatever initialization is required to render the scene properly with the indicated GSG.

It is not strictly necessary to call this, since the GSG will initialize itself when the scene is rendered, but this may take some of the overhead away from that process.

In particular, this will ensure that textures and vertex buffers within the scene are loaded into graphics memory.

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.

void NodePath::set_bin ( const 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_max_search_depth ( int  max_search_depth) [inline, static]

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.

A convenience function to set up a normal map on this geometry.

This uses the single highest-priority light on the object only. It also requires multitexture, and consumes at least two texture stages, in addition to what may already be in use.

The normal_map parameter is the texture that contains the normal map information (with a 3-d delta vector encoded into the r,g,b of each texel). texcoord_name is the name of the texture coordinate set that contains the tangent and binormal we wish to use. If preserve_color is true, then one additional texture stage is consumed to blend in the geometry's original vertex color.

Only one normal map may be in effect through this interface at any given time.

If there are multiple texture stages specified (possibly on multiple different nodes at different levels), they will all be applied to geometry together, according to the stage specification set up in the TextureStage object.

void NodePath::set_texture_off ( int  priority = 0)

Sets the geometry at this level and below to render using no texture, on any stage.

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

Sets the transform object on this node, relative to the other node.

This computes a new transform object that will have the indicated value when seen from the other node.

void NodePath::set_transparency ( TransparencyAttrib::Mode  mode,

Specifically sets or disables transparent rendering mode on this particular node.

If no other nodes override, this will cause items with a non-1 value for alpha color to be rendered partially transparent.

Specifically sets or disables two-sided rendering mode on this particular node.

If no other nodes override, this will cause backfacing polygons to be drawn (in two-sided mode, true) or culled (in one-sided mode, false).

void NodePath::show ( ) [inline]

Undoes the effect of a previous hide() on this node: makes the referenced node (and the entire subgraph below this node) visible to all cameras.

This will not reveal the node if a parent node has been hidden.

void NodePath::show ( DrawMask  camera_mask) [inline]

Makes the referenced node visible just to the cameras whose camera_mask shares the indicated bits.

This undoes the effect of a previous hide() call. It will not reveal the node if a parent node has been hidden. However, see show_through().

Causes the bounding volume of the bottom node and all of its descendants (that is, the bounding volume associated with the the bottom arc) to be rendered, if possible.

The rendering method is less than optimal; this is intended primarily for debugging.

void NodePath::show_through ( ) [inline]

Makes the referenced node visible just to the cameras whose camera_mask shares the indicated bits.

Unlike show(), this will reveal the node even if a parent node has been hidden, thus "showing through" a parent's hide().

void NodePath::show_through ( DrawMask  camera_mask) [inline]

Makes the referenced node visible just to the cameras whose camera_mask shares the indicated bits.

Unlike show(), this will reveal the node even if a parent node has been hidden via the one-parameter hide() method, thus "showing through" a parent's hide(). (However, it will not show through a parent's hide() call if the no-parameter form of hide() was used.)

References PandaNode::adjust_draw_mask(), BitMask< PN_uint32, 32 >::all_off(), is_empty(), and node().

Similar to show_bounds(), this draws a bounding box representing the "tight" bounds of this node and all of its descendants.

The bounding box is recomputed every frame by reexamining all of the vertices; this is far from efficient, but this is intended for debugging.

void NodePath::stash ( int  sort = 0,
Thread current_thread = Thread::get_current_thread() 
)

Removes the referenced node (and the entire subgraph below this node) from the scene graph in any normal sense.

The node will no longer be visible and is not tested for collisions; furthermore, no normal scene graph traversal will visit the node. The node's bounding volume no longer contributes to its parent's bounding volume.

A stashed node cannot be located by a normal find() operation (although a special find string can still retrieve it).

Similar to reparent_to(), but the node is added to its new parent's stashed list, so that the result is equivalent to calling reparent_to() immediately followed by stash().

Searches through all TextureStages at this node and below.

Any TextureStages that share the same name as the indicated TextureStage object are replaced with this object, thus ensuring that all geometry at this node and below with a particular TextureStage name is using the same TextureStage object.
