virtual LMatrix4d get_frame(int n) const
Returns the transform matrix corresponding to this joint position in the nth frame.
virtual void set_frame(int n, const LMatrix4d &mat)
Sets the transform matrix corresponding to this joint position in the nth frame.

void register_type(TypeHandle &type_handle, const std::string &name)
This inline function is just a convenient way to call TypeRegistry::register_type(), along with zero to four record_derivation()s.

virtual void extend_to(int num_frames)
Extends the table to the indicated number of frames.
virtual void zero_channels(const std::string &components)
Zeroes out the named components of the transform in the animation frames.
virtual void optimize()
Resets the table before writing to disk so that redundant rows (e.g.
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 bool do_rebuild(EggCharacterDb &db)
Rebuilds the entire table all at once, based on the frames added by repeated calls to add_rebuild_fra...
virtual bool add_frame(const LMatrix4d &mat)
Appends a new frame onto the end of the data, if possible; returns true if not possible, or false otherwise (e.g.
This corresponds to an <Xfm$Anim_S$> entry, which is a collection of up to nine <S$Anim> entries that...

virtual void quantize_channels(const std::string &components, double quantum)
Rounds the named components of the transform to the nearest multiple of quantum.

Performs the actual reparenting operation by removing the node from its old parent and associating it...
virtual double get_frame_rate() const
Returns the stated frame rate of this particular joint, or 0.0 if it doesn&#39;t state.
