Detailed Description

This is a base class for EggJointNodePointer and EggMatrixTablePointer.

It stores a back pointer to either a <Joint> entry or an xform

, and thus presents an interface that returns 1-n matrices, one for each frame. (<Joint> entries, for model files, appear the same as one-frame animations.)

Member Function Documentation

◆ add_frame()

bool EggJointPointer::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 in EggMatrixTablePointer.

Definition at line 24 of file eggJointPointer.cxx.

◆ apply_default_pose()

void EggJointPointer::apply_default_pose ( EggJointPointer * source_joint,
int frame )
virtual

Applies the pose from the indicated frame of the indicated source joint as the initial pose for this joint.

Reimplemented in EggJointNodePointer.

Definition at line 87 of file eggJointPointer.cxx.

Referenced by EggJointData::apply_default_pose().

◆ do_finish_reparent()

virtual void EggJointPointer::do_finish_reparent ( EggJointPointer * new_parent)
pure virtual

◆ do_rebuild()

bool EggJointPointer::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.

Reimplemented in EggJointNodePointer, and EggMatrixTablePointer.

◆ expose()

void EggJointPointer::expose ( EggGroup::DCSType dcs_type)

Flags the joint with the indicated DCS flag so that it will be loaded as a separate node in the player.

Reimplemented in EggJointNodePointer.
