Public Member Functions

 __init__ (const EggTable copy)
 
 __init__ (str name)
 
EggTable::TableType getTableType ()
 
bool hasTransform ()
 Returns true if the table contains a transform description, false otherwise. More...
 
EggTable operator= (const EggTable copy)
 
 setTableType (EggTable::TableType type)
 
- Public Member Functions inherited from EggGroupNode
 __init__ (const EggGroupNode copy)
 
 __init__ (str name)
 
EggNode addChild (EggNode node)
 Adds the indicated child to the group and returns it. If the child node is already a child of some other node, removes it first. More...
 
 applyFirstAttribute (bool recurse)
 Sets the first vertex of the triangle (or each component) to the primitive normal and/or color, if the primitive is flat-shaded. This reflects the DirectX convention of storing flat-shaded properties on the first vertex, although it is not usually a convention in Egg. More...
 
 applyLastAttribute (bool recurse)
 Sets the last vertex of the triangle (or each component) to the primitive normal and/or color, if the primitive is flat-shaded. This reflects the OpenGL convention of storing flat-shaded properties on the last vertex, although it is not usually a convention in Egg. More...
 
 clear ()
 
 clearConnectedShading ()
 Resets the connected_shading information on all primitives at this node and below, so that it may be accurately rederived by the next call to get_connected_shading(). More...
 
bool empty ()
 
EggNode findChild (str name)
 Returns the child of this node whose name is the indicated string, or NULL if there is no child of this node by that name. Does not search recursively. More...
 
 forceFilenames (const Filename directory)
 Similar to resolve_filenames, but each non-absolute filename encountered is arbitrarily taken to be in the indicated directory, whether or not the so-named filename exists. More...
 
object getChildren ()
 
 getConnectedShading ()
 Queries the connected_shading information on all primitives at this node and below, to ensure that it has been completely filled in before we start mucking around with vertices. More...
 
EggNode getFirstChild ()
 Returns the first child in the group's list of children, or NULL if the list of children is empty. Can be used with get_next_child() to return the complete list of children without using the iterator class; however, this is non-thread-safe, and so is not recommended except for languages other than C++ which cannot use the iterators. More...
 
EggNode getNextChild ()
 Returns the next child in the group's list of children since the last call to get_first_child() or get_next_child(), or NULL if the last child has been returned. Can be used with get_first_child() to return the complete list of children without using the iterator class; however, this is non-thread-safe, and so is not recommended except for languages other than C++ which cannot use the iterators. More...
 
bool hasAbsolutePathnames ()
 Returns true if any nodes at this level and below include a reference to a file via an absolute pathname, or false if all references are relative. More...
 
bool hasNormals ()
 Returns true if any of the primitives (e.g. polygons) defined within this group or below have either face or vertex normals defined, false otherwise. More...
 
bool hasPrimitives ()
 Returns true if there are any primitives (e.g. polygons) defined within this group or below, false otherwise. More...
 
bool jointHasPrimitives ()
 Returns true if there are any primitives (e.g. polygons) defined within this group or below, but the search does not include nested joints. More...
 
 makePointPrimitives ()
 Creates PointLight primitives to reference any otherwise unreferences vertices discovered in this group or below. More...
 
 meshTriangles (int flags)
 Combine triangles together into triangle strips, at this group and below. More...
 
EggGroupNode operator= (const EggGroupNode copy)
 
 postApplyFlatAttribute (bool recurse)
 Intended as a followup to apply_last_attribute(), this also sets an attribute on the first vertices of the primitive, if they don't already have an attribute set, just so they end up with something. More...
 
 recomputePolygonNormals (CoordinateSystem cs)
 Recomputes all the polygon normals for polygon geometry at this group node and below so that they accurately reflect the vertex positions. Normals are removed from the vertices and defined only on polygons, giving the geometry a faceted appearance. More...
 
bool recomputeTangentBinormal (const GlobPattern uv_name)
 This function recomputes the tangent and binormal for the named texture coordinate set for all vertices at this level and below. Use the empty string for the default texture coordinate set. More...
 
bool recomputeTangentBinormal (const VectorString names)
 This function recomputes the tangent and binormal for the named texture coordinate sets. Returns true if anything was done. More...
 
bool recomputeTangentBinormalAuto ()
 This function recomputes the tangent and binormal for any texture coordinate set that affects a normal map. Returns true if anything was done. More...
 
 recomputeVertexNormals (double threshold, CoordinateSystem cs)
 Recomputes all the vertex normals for polygon geometry at this group node and below so that they accurately reflect the vertex positions. A shared edge between two polygons (even in different groups) is considered smooth if the angle between the two edges is less than threshold degrees. More...
 
EggNode removeChild (EggNode node)
 Removes the indicated child node from the group and returns it. If the child was not already in the group, does nothing and returns NULL. More...
 
int removeInvalidPrimitives (bool recurse)
 Removes primitives at this level and below which appear to be degenerate; e.g. polygons with fewer than 3 vertices, etc. Returns the number of primitives removed. More...
 
int removeUnusedVertices (bool recurse)
 Removes all vertices from VertexPools within this group or below that are not referenced by at least one primitive. Also collapses together equivalent vertices, and renumbers all vertices after the operation so their indices are consecutive, beginning at zero. Returns the total number of vertices removed. More...
 
int renameNodes (VectorString strip_prefix, bool recurse)
 Rename by stripping out the prefix. More...
 
 resolveFilenames (const DSearchPath searchpath)
 Walks the tree and attempts to resolve any filenames encountered. This looks up filenames along the specified search path; it does not automatically search the model_path for missing files. More...
 
 reverseVertexOrdering ()
 Reverses the vertex ordering of all polygons defined at this node and below. Does not change the surface normals, if any. More...
 
EggGroupNode::SizeType size ()
 
 stealChildren (EggGroupNode other)
 Moves all the children from the other node to this one. This is especially useful because the group node copy assignment operator does not copy children. More...
 
 stripNormals ()
 Removes all normals from primitives, and the vertices they reference, at this node and below. More...
 
int triangulatePolygons (int flags)
 Replace all higher-order polygons at this point in the scene graph and below with triangles. Returns the total number of new triangles produced, less degenerate polygons removed. More...

 Applies per-vertex normal and color to all vertices, if they are in fact per-vertex (and different for each vertex), or moves them to the primitive if they are all the same. More...

- Public Member Functions inherited from ReferenceCount
int getRefCount ()
 Returns the current reference count. More...

Detailed Description

This corresponds to a.

a <Bundle> entry. As such, it doesn't actually contain a table of numbers, but it may be a parent to an EggSAnimData or an EggXfmAnimData, which do. It may also be a parent to another

<Bundle>, establishing a hierarchy of tables.
