Returns the coordinate frame of the vertices referenced by primitives at or under this node.

This is not the same as get_node_frame().

Generally, vertices in an egg file are stored in the global coordinate space, regardless of the transforms defined at each node. Thus, get_vertex_frame() will usually return the identity transform (global coordinate space). However, primitives under an entry reference their vertices in the coordinate system under effect at the time of the . Thus, nodes under an entry may return this non-identity matrix.

Specifically, this may return a non-identity matrix only if is_local_coord() is true.

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.

void EggPrimitive::remove_doubled_verts (  bool  closed  )  [inherited]
 

Certain kinds of primitives, particularly polygons, don't like to have the same vertex repeated consecutively.

Unfortunately, some modeling programs (like MultiGen) make this an easy mistake to make.

It's handy to have a function to remove these redundant vertices. If closed is true, it also checks that the first and last vertices are not the same.

This function identifies repeated vertices by pointer only; it does not remove consecutive equivalent but different vertices.

Reimplemented in EggVertexPool.

Definition at line 327 of file eggNode.I.

void EggNode::transform_vertices_only (  const LMatrix4d &  mat  )  [inline, inherited]
 

Applies the indicated transformation only to vertices that appear in global space within vertex pools at this node and below.

Joints and other transforms are not affected, nor are local vertices.

Definition at line 352 of file eggNode.I.

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. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().

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.

void EggNode::update_under (  int  depth_offset  )  [protected, virtual, inherited]
 

This function is called from within EggGroupNode whenever the parentage of the node has changed.

It should update the depth and under_instance flags accordingly.

depth_offset is the difference between the old depth value and the new value. It should be consistent with the supplied depth value. If it is not, we have some error.

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>".
