bool get_matrix(const EggJointPointer *joint, TableType type, int frame, LMatrix4d &mat) const
Looks up the data for the indicated joint, type, and frame, and fills it in result (and returns true)...
A base class for nodes in the hierarchy that are not leaf nodes.
void steal_children(EggGroupNode &other)
Moves all the children from the other node to this one.
The main glue of the egg hierarchy, this corresponds to the <Group>, <Instance>, and <Joint> type nod...
This stores a pointer back to a <Joint> node.
virtual void set_frame(int n, const LMatrix4d &mat)
Sets the transform matrix corresponding to this joint position in the nth frame.
virtual void expose(EggGroup::DCSType dcs_type)
Flags the joint with the indicated DCS flag so that it will be loaded as a separate node in the playe...
virtual void do_finish_reparent(EggJointPointer *new_parent)
Performs the actual reparenting operation by removing the node from its old parent and associating it...
virtual EggJointPointer * make_new_joint(const std::string &name)
Creates a new child of the current joint in the egg data, and returns a pointer to it.
virtual void apply_default_pose(EggJointPointer *source_joint, int frame)
Applies the pose from the indicated frame of the indicated source joint as the initial pose for this ...
virtual bool has_vertices() const
Returns true if there are any vertices referenced by the node this points to, false otherwise.
virtual LMatrix4d get_frame(int n) const
Returns the transform matrix corresponding to this joint position in the nth frame.
virtual void move_vertices_to(EggJointPointer *new_joint)
Moves the vertices assigned to this joint into the other joint (which should be of the same type).

Returns the number of frames of animation for this particular joint.
virtual void set_name(const std::string &name)
Applies the indicated name change to the egg file.
virtual bool do_rebuild(EggCharacterDb &db)
