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 25 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 88 of file eggJointPointer.cxx.

◆ 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 EggMatrixTablePointer, and EggJointNodePointer.

Definition at line 48 of file eggJointPointer.cxx.

◆ expose()

void EggJointPointer::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 in EggJointNodePointer.

Definition at line 65 of file eggJointPointer.cxx.

◆ move_vertices_to()

void EggJointPointer::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 in EggJointNodePointer.

Definition at line 34 of file eggJointPointer.cxx.

◆ optimize()

void EggJointPointer::optimize ( )
virtual

Resets the table before writing to disk so that redundant rows (e.g.

i { 1 1 1 1 1 1 1 1 }) are collapsed out.

Reimplemented in EggMatrixTablePointer.

Definition at line 57 of file eggJointPointer.cxx.

◆ quantize_channels()

void EggJointPointer::quantize_channels ( const std::string &  components,
double  quantum 
)
virtual

Rounds the named components of the transform to the nearest multiple of quantum.

Reimplemented in EggMatrixTablePointer.

Definition at line 80 of file eggJointPointer.cxx.

◆ zero_channels()

void EggJointPointer::zero_channels ( const std::string &  components)
virtual

Zeroes out the named components of the transform in the animation frames.

Reimplemented in EggMatrixTablePointer.

Definition at line 72 of file eggJointPointer.cxx.
