## 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.

Definition at line 29 of file eggMatrixTablePointer.cxx.

## Member Function Documentation

## ◆ add_frame()

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 141 of file eggMatrixTablePointer.cxx.

## ◆ do_finish_reparent()

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 154 of file eggMatrixTablePointer.cxx.

## ◆ do_rebuild()

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.
