Member Function Documentation

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(), and get_num_frames().

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 EggGroupNode::steal_children().

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 EggCharacterDb::get_matrix().

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.

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.

Definition at line 71 of file eggJointNodePointer.cxx.

References LMatrix4d::ident_mat().

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

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.

Referenced by apply_default_pose().

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.

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

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from EggJointPointer.

Definition at line 57 of file eggJointNodePointer.h.

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.

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.

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.

Definition at line 88 of file eggJointNodePointer.cxx.

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

Applies the indicated name change to the egg file.

Reimplemented from EggBackPointer.

Definition at line 239 of file eggJointNodePointer.cxx.
