Returns the coordinate frame of the vertices referenced by primitives at or under this node. This is not the same as get_node_frame().

void EggGroup::r_transform (  const LMatrix4d &  mat, const LMatrix4d &  inv, CoordinateSystem  to_cs )  [protected, virtual]

This is called from within the egg code by transform(). It applies a transformation matrix to the current node in some sensible way, then continues down the tree. The first matrix is the transformation to apply; the second is its inverse. The third parameter is the coordinate system we are changing to, or CS_default if we are not changing coordinate systems.

void EggGroupNode::recompute_polygon_normals (  CoordinateSystem  cs = CS_default  )  [inherited]

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. This function also removes degenerate polygons that do not have enough vertices to define a normal. It does not affect normals for other kinds of primitives like Nurbs or Points. This function does not remove or adjust vertices in the vertex pool; it only adds new vertices with the normals removed. Thus, it is a good idea to call remove_unused_vertices() after calling this. Definition at line 532 of file eggGroupNode.cxx.

void EggGroupNode::recompute_vertex_normals (  double  threshold, CoordinateSystem  cs = CS_default )  [inherited]

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. This function also removes degenerate polygons that do not have enough vertices to define a normal. It does not affect normals for other kinds of primitives like Nurbs or Points. This function does not remove or adjust vertices in the vertex pool; it only adds new vertices with the correct normals. Thus, it is a good idea to call remove_unused_vertices() after calling this.

int ReferenceCount::ref (   )  const [inline, inherited]

Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is the new reference count.

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. Definition at line 754 of file eggGroupNode.cxx.

bool EggGroup::remove_object_type (  const string &  object_type  )

Removes the first instance of the indicated object type from the group if it is present. Returns true if the object type was found and removed, false otherwise. Definition at line 171 of file eggGroup.cxx. References GT_instance, and GT_joint.

int EggGroupNode::remove_unused_vertices (   )  [inherited]

Removes all vertices from VertexPools within this group or below that are not referenced by at least one primitive. Also renumbers all vertices after the operation so their indices are consecutive, beginning at zero. Returns the total number of vertices removed. Note that this operates on the VertexPools within this group level, without respect to primitives that reference these vertices (unlike other functions like strip_normals()). It is therefore most useful to call this on the EggData root, rather than on a subgroup within the hierarchy, since a VertexPool may appear anywhere in the hierarchy.

void EggRenderMode::set_alpha_mode (  AlphaMode  mode  )  [inline, inherited]

Specifies precisely how the transparency for this geometry should be achieved, or if it should be used. The default, AM_unspecified, is to use transparency if the geometry has a color whose alpha value is non-1, or if it has a four-channel texture applied; otherwise, AM_on forces transparency on, and AM_off forces it off. The other flavors of transparency are specific ways to turn on transparency, which may or may not be supported by a particular rendering backend. Definition at line 169 of file eggRenderMode.I.

void EggGroup::set_billboard_center (  const LPoint3d &  billboard_center  )  [inline]

Sets the point around which the billboard will rotate, if this node contains a billboard specification. If a billboard type is given but no billboard_center is specified, then the group node is treated as an , and the billboard rotates around the origin. If, however, a billboard_center is specified, then the group node is *not* treated as an , and the billboard rotates around the specified point. The point is in the same coordinate system as the vertices of this node: usually global, but possibly local if there is an somewhere above.

int ReferenceCount::unref (   )  const [inline, inherited]

Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero.

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is the new reference count.

Returns the number of elements between vref_begin() and vref_end(). This interface is not safe to use outside of PANDAEGG.DLL. Definition at line 839 of file eggGroup.I.

void EggGroup::write (  ostream &  out, int  indent_level )  const [virtual]

Writes the group and all of its children to the indicated output stream in Egg format. Reimplemented from EggGroupNode. Definition at line 193 of file eggGroup.cxx.

void EggNamedObject::write_header (  ostream &  out, int  indent_level, const char *  egg_keyword )  const [inherited]

Writes the first line of the egg object, e.g. "<Group> group_name {" or some such. It automatically enquotes the name if it contains any special characters. egg_keyword is the keyword that begins the line, e.g. "<Group>". Definition at line 46 of file eggNamedObject.cxx. Referenced by EggPoint::cleanup(), EggNurbsSurface::is_closed_u(), and EggExternalReference::operator=().

void EggGroup::write_vertex_ref (  ostream &  out, int  indent_level )  const [protected]

Writes out the vertex ref component of the group body only. This may consist of a number of entries, each with its own membership value. Definition at line 776 of file eggGroup.cxx.
