Member Function Documentation

bool EggJointPointer::add_frame (  const LMatrix4d &  mat  )  [virtual, inherited]

Appends a new frame onto the end of the data, if possible; returns true if not possible, or false otherwise (e.g. for a static joint). Reimplemented in EggMatrixTablePointer. Definition at line 41 of file eggJointPointer.cxx. References EggJointPointer::_rebuild_frames.

bool EggJointNodePointer::add_rebuild_frame (  const LMatrix4d &  mat  )  [virtual]

Adds a new frame to the set of rebuild frames. See begin_rebuild() and do_rebuild(). Returns true if this is valid, false otherwise (e.g. adding multiple frames to a static joint). Reimplemented from EggJointPointer. Definition at line 144 of file eggJointNodePointer.cxx.

void EggJointPointer::begin_rebuild (   )  [inherited]

Resets the set of rebuild frames in preparation for rebuilding the complete table of frames. Repeated calls to add_rebuild_frame() will build up the frames without changing the values returned by get_frame(); the table will eventually be updated when do_rebuild is called. Definition at line 64 of file eggJointPointer.cxx.

bool EggJointNodePointer::do_rebuild (   )  [virtual]

Rebuilds the entire table all at once, based on the frames added by repeated calls to add_rebuild_frame() since the last call to begin_rebuild(). Until do_rebuild() is called, the animation table is not changed. The return value is true if all frames are acceptable, or false if there is some problem. Reimplemented from EggJointPointer. Definition at line 177 of file eggJointNodePointer.cxx.

virtual TypeHandle EggJointNodePointer::force_init_type (  void   )  [inline, virtual]

Reimplemented from EggJointPointer. Definition at line 65 of file eggJointNodePointer.h.

TypeHandle EggJointNodePointer::get_class_type (  void   )  [inline, static]

Reimplemented from EggJointPointer. Definition at line 54 of file eggJointNodePointer.h.

LMatrix4d EggJointNodePointer::get_frame (  int  n  )  const [virtual]

Returns the transform matrix corresponding to this joint position in the nth frame. In the case of a EggJointNodePointer, which just stores a pointer to a entry for a character model (not an animation table), there is always exactly one frame: the rest pose. Implements EggJointPointer. Definition at line 98 of file eggJointNodePointer.cxx. References EggJointPointer::_rebuild_frames, and EggJointPointer::add_rebuild_frame().

int EggJointNodePointer::get_num_frames (   )  const [virtual]

Returns the number of frames of animation for this particular joint. In the case of a EggJointNodePointer, which just stores a pointer to a entry for a character model (not an animation table), there is always exactly one frame: the rest pose. Implements EggJointPointer. Definition at line 73 of file eggJointNodePointer.cxx. References _joint, and nassertr.

virtual TypeHandle EggJointNodePointer::get_type (  void   )  const [inline, virtual]

Reimplemented from EggJointPointer. Definition at line 62 of file eggJointNodePointer.h. References _type_handle.

void EggJointNodePointer::init_type (  void   )  [inline, static]

Reimplemented from EggJointPointer. Definition at line 57 of file eggJointNodePointer.h. Referenced by ConfigureFn().

void EggJointPointer::optimize (   )  [virtual, inherited]

Resets the table before writing to disk so that redundant rows (e.g. i { 1 1 1 1 1 1 1 1 }) are collapsed out. Reimplemented in EggMatrixTablePointer. Definition at line 134 of file eggJointPointer.cxx. Referenced by EggJointData::do_rebuild().

void EggJointNodePointer::set_frame (  int  n, const LMatrix4d &  mat )  [virtual]

Sets the transform matrix corresponding to this joint position in the nth frame. In the case of a EggJointNodePointer, which just stores a pointer to a entry for a character model (not an animation table), there is always exactly one frame: the rest pose. Implements EggJointPointer. Definition at line 124 of file eggJointNodePointer.cxx. References _joint, and EggJointPointer::_rebuild_frames.
