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

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 29 of file eggJointPointer.cxx.

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 110 of file eggJointPointer.cxx.

Referenced by EggJointData::apply_default_pose().

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 57 of file eggJointPointer.cxx.

Referenced by EggJointData::do_joint_rebuild(), and EggJointData::do_rebuild_all().

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 79 of file eggJointPointer.cxx.

Referenced by EggJointData::expose().

static void EggJointPointer::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 EggBackPointer.

Reimplemented in EggMatrixTablePointer, and EggJointNodePointer.

Definition at line 58 of file eggJointPointer.h.

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 40 of file eggJointPointer.cxx.

Referenced by EggJointData::move_vertices_to().

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 69 of file eggJointPointer.cxx.

Referenced by EggJointData::optimize().

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

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

Reimplemented in EggMatrixTablePointer.

Definition at line 99 of file eggJointPointer.cxx.

Referenced by EggJointData::quantize_channels().

void EggJointPointer::zero_channels ( const string &  components) [virtual]

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

Reimplemented in EggMatrixTablePointer.

Definition at line 89 of file eggJointPointer.cxx.
