Detailed Description

This stores a pointer back to an EggXfmSAnim table (i.e.

an <Xfm$Anim_S$> entry in an egg file), corresponding to the animation data from a single bundle for this joint.

Member Function Documentation

bool EggMatrixTablePointer::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 from EggJointPointer.

Definition at line 155 of file eggMatrixTablePointer.cxx.

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 171 of file eggMatrixTablePointer.cxx.

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 203 of file eggMatrixTablePointer.cxx.

References EggCharacterDb::get_matrix().

void EggMatrixTablePointer::extend_to ( int  num_frames) [virtual]

Extends the table to the indicated number of frames.

Reimplemented from EggBackPointer.

Definition at line 94 of file eggMatrixTablePointer.cxx.

References LMatrix4d::ident_mat().

LMatrix4d EggMatrixTablePointer::get_frame ( int  n) const [virtual]

Returns the transform matrix corresponding to this joint position in the nth frame.

Implements EggJointPointer.

Definition at line 118 of file eggMatrixTablePointer.cxx.

References get_num_frames(), and LMatrix4d::ident_mat().

double EggMatrixTablePointer::get_frame_rate ( ) const [virtual]

Returns the stated frame rate of this particular joint, or 0.0 if it doesn't state.

Reimplemented from EggBackPointer.

Definition at line 65 of file eggMatrixTablePointer.cxx.

int EggMatrixTablePointer::get_num_frames ( ) const [virtual]

Returns the number of frames of animation for this particular joint.

Implements EggJointPointer.

Definition at line 80 of file eggMatrixTablePointer.cxx.

Referenced by get_frame(), and set_frame().

static void EggMatrixTablePointer::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 64 of file eggMatrixTablePointer.h.

EggJointPointer * EggMatrixTablePointer::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 304 of file eggMatrixTablePointer.cxx.

References EggGroupNode::add_child(), EggXfmSAnim::add_data(), and LMatrix4d::ident_mat().

void EggMatrixTablePointer::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 from EggJointPointer.

Definition at line 241 of file eggMatrixTablePointer.cxx.

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

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

Reimplemented from EggJointPointer.

Definition at line 278 of file eggMatrixTablePointer.cxx.

References TypedObject::is_of_type(), and EggAnimData::quantize().

void EggMatrixTablePointer::set_frame ( int  n,
const LMatrix4d mat 
) [virtual]

Sets the transform matrix corresponding to this joint position in the nth frame.

Implements EggJointPointer.

Definition at line 142 of file eggMatrixTablePointer.cxx.

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

Applies the indicated name change to the egg file.

Reimplemented from EggBackPointer.

Definition at line 324 of file eggMatrixTablePointer.cxx.

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

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

Reimplemented from EggJointPointer.
