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

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.

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.

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.

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.

void NodePath::detach_node ( Thread current_thread = Thread::get_current_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.

string NodePath::encode_to_bam_stream ( ) const [inline]

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

Returns empty string on failure. This is similar to write_bam_stream().

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

Definition at line 2377 of file nodePath.I.

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.

*int NodePath::flatten_light ( )

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 6437 of file nodePath.cxx.

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

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.

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.

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.

void NodePath::premunge_scene ( GraphicsStateGuardianBase gsg = NULL)

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 within the scene are loaded in texture memory, and display lists are built up from static geometry.

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.

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_clip_plane ( const NodePath clip_plane,

Adds the indicated clipping plane to the list of planes that apply to geometry at this node and below.

The clipping plane itself, a PlaneNode, should be parented into the scene graph elsewhere, to represent the plane's position in space; but until set_clip_plane() is called it will clip no geometry.

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.

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.

void NodePath::set_depth_offset ( int  bias,

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.

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.

void NodePath::set_normal_map ( Texture normal_map,
const string &  texcoord_name = string(),

)

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.

Sets up the point geometry at this level and below to render as perspective sprites (that is, billboarded quads).

The thickness, as specified with set_render_mode_thickness(), is the width of each point in 3-D units, unless it is overridden on a per-vertex basis. This does not affect geometry other than points.

void NodePath::unify_texture_stages ( TextureStage stage)

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.

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

Undoes the effect of a previous stash() on this node: makes the referenced node (and the entire subgraph below this node) once again part of the scene graph.

bool NodePath::verify_complete ( Thread current_thread = Thread::get_current_thread()) const
bool NodePath::write_bam_file ( const Filename filename) const

Writes the contents of this node and below out to a bam file with the indicated filename.

This file may then be read in again, as is, at some later point. Returns true if successful, false on some kind of error.
