Member Function Documentation

◆ apply_default_pose()

void EggJointNodePointer::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 from EggJointPointer.

Definition at line 189 of file eggJointNodePointer.cxx.

References get_frame(), get_num_frames(), and has_vertices().

Referenced by expose().

◆ do_finish_reparent()

void EggJointNodePointer::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 101 of file eggJointNodePointer.cxx.

References move_vertices_to(), and EggGroupNode::steal_children().

Referenced by set_frame().

◆ do_rebuild()

bool EggJointNodePointer::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 from EggJointPointer.

Definition at line 153 of file eggJointNodePointer.cxx.

References expose(), and EggCharacterDb::get_matrix().

Referenced by move_vertices_to().

◆ expose()

void EggJointNodePointer::expose ( EggGroup::DCSType  dcs_type)
virtual

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

Reimplemented from EggJointPointer.

Definition at line 175 of file eggJointNodePointer.cxx.

References apply_default_pose().

Referenced by do_rebuild().

◆ get_frame()

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 <Joint> entry for a character model (not an animation table), there is always exactly one frame: the rest pose.

Implements EggJointPointer.

Referenced by EggJointData::add_back_pointer(), apply_default_pose(), and get_num_frames().

◆ get_num_frames()

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 <Joint> entry for a character model (not an animation table), there is always exactly one frame: the rest pose.

Implements EggJointPointer.

Definition at line 55 of file eggJointNodePointer.cxx.

References get_frame().

Referenced by apply_default_pose().

◆ has_vertices()

bool EggJointNodePointer::has_vertices ( ) const
virtual

Returns true if there are any vertices referenced by the node this points to, false otherwise.

For certain kinds of back pointers (e.g. table animation entries), this is always false.

Reimplemented from EggBackPointer.

Definition at line 211 of file eggJointNodePointer.cxx.

References make_new_joint().

Referenced by apply_default_pose().

◆ make_new_joint()

EggJointPointer * EggJointNodePointer::make_new_joint ( const string &  name)
virtual

Creates a new child of the current joint in the egg data, and returns a pointer to it.

Implements EggJointPointer.

Definition at line 226 of file eggJointNodePointer.cxx.

References set_name().

Referenced by has_vertices().

◆ move_vertices_to()

void EggJointNodePointer::move_vertices_to ( EggJointPointer new_joint)
virtual

Moves the vertices assigned to this joint into the other joint (which should be of the same type).

Reimplemented from EggJointPointer.

Definition at line 127 of file eggJointNodePointer.cxx.

References do_rebuild().

Referenced by do_finish_reparent().

◆ set_frame()

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 <Joint> entry for a character model (not an animation table), there is always exactly one frame: the rest pose.

Implements EggJointPointer.

◆ set_name()

void EggJointNodePointer::set_name ( const string &  name)
virtual

Applies the indicated name change to the egg file.

Reimplemented from EggBackPointer.
