EggMatrixTablePointer (EggObject *object) | |
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. | |
virtual void | do_finish_reparent (EggJointPointer *new_parent) |
Performs the actual reparenting operation by removing the node from its old parent and associating it with its new parent, if any. | |
virtual bool | do_rebuild (EggCharacterDb &db) |
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(). | |
virtual void | extend_to (int num_frames) |
Extends the table to the indicated number of frames. | |
virtual TypeHandle | force_init_type () |
virtual LMatrix4d | get_frame (int n) const |
Returns the transform matrix corresponding to this joint position in the nth frame. | |
virtual double | get_frame_rate () const |
Returns the stated frame rate of this particular joint, or 0.0 if it doesn't state. | |
virtual int | get_num_frames () const |
Returns the number of frames of animation for this particular joint. | |

Resets the table before writing to disk so that redundant rows (e.g. | |
virtual void | quantize_channels (const string &components, double quantum) |
Rounds the named components of the transform to the nearest multiple of quantum. | |
virtual void | set_frame (int n, const LMatrix4d &mat) |
Sets the transform matrix corresponding to this joint position in the nth frame. | |
virtual void | set_name (const string &name) |
Applies the indicated name change to the egg file. | |
virtual void | zero_channels (const string &components) |
Zeroes out the named components of the transform in the animation frames. | |

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.

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 155 of file eggMatrixTablePointer.cxx.
void EggMatrixTablePointer::do_finish_reparent | ( | EggJointPointer * | new_parent | ) | [virtual] |
Performs the actual reparenting operation by removing the node from its old parent and associating it with its new parent, if any.
Implements EggJointPointer.
Definition at line 171 of file eggMatrixTablePointer.cxx.
bool EggMatrixTablePointer::do_rebuild | ( | EggCharacterDb & | db | ) | [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.
