Detailed Description

This stores a pointer back to an EggXfmSAnim table (i.e.

an <Xfm$Anim_S$> entry in an egg file), corresponding to the animation data from a single bundle for this joint.

Member Function Documentation

bool EggMatrixTablePointer::add_frame (  const LMatrix4d &  mat  )  [virtual]

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 from EggJointPointer. Definition at line 139 of file eggMatrixTablePointer.cxx. References EggJointPointer::_rebuild_frames, _xform, and NULL.

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

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 in EggJointNodePointer. Definition at line 83 of file eggJointPointer.cxx. Referenced by EggJointNodePointer::get_frame().

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 EggMatrixTablePointer::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 172 of file eggMatrixTablePointer.cxx.

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

Reimplemented from EggJointPointer. Definition at line 75 of file eggMatrixTablePointer.h.

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

Reimplemented from EggJointPointer. Definition at line 64 of file eggMatrixTablePointer.h.

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

Returns the transform matrix corresponding to this joint position in the nth frame. Implements EggJointPointer. Definition at line 97 of file eggMatrixTablePointer.cxx. References _xform, get_num_frames(), and nassertv.

int EggMatrixTablePointer::get_num_frames (   )  const [virtual]

Returns the number of frames of animation for this particular joint. Implements EggJointPointer. Definition at line 78 of file eggMatrixTablePointer.cxx. References _xform, and nassertr. Referenced by get_frame().

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

Reimplemented from EggJointPointer. Definition at line 72 of file eggMatrixTablePointer.h.

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

Reimplemented from EggJointPointer. Definition at line 67 of file eggMatrixTablePointer.h. References _type_handle.

void EggMatrixTablePointer::optimize (   )  [virtual]

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 from EggJointPointer. Definition at line 206 of file eggMatrixTablePointer.cxx.

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

Sets the transform matrix corresponding to this joint position in the nth frame. Implements EggJointPointer. Definition at line 121 of file eggMatrixTablePointer.cxx. References _xform.
