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.)

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().

TypedObject * TypedObject::as_typed_object ( ) [inline, inherited]

Returns the object, upcast (if necessary) to a TypedObject pointer.

Definition at line 99 of file typedObject.I.

const TypedObject * TypedObject::as_typed_object ( ) const [inline, inherited]

Returns the object, upcast (if necessary) to a TypedObject pointer.

Definition at line 110 of file typedObject.I.

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 EggJointNodePointer, and EggMatrixTablePointer.

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().

void EggBackPointer::extend_to ( int  num_frames) [virtual, inherited]

Extends the table to the indicated number of frames.

Reimplemented in EggMatrixTablePointer, and EggScalarTablePointer.

Definition at line 46 of file eggBackPointer.cxx.

Referenced by EggComponentData::extend_to().

double EggBackPointer::get_frame_rate ( ) const [virtual, inherited]

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

Reimplemented in EggMatrixTablePointer, and EggScalarTablePointer.

Definition at line 36 of file eggBackPointer.cxx.

Referenced by EggComponentData::get_frame_rate().

int TypedObject::get_type_index ( ) const [inline, inherited]

Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.

This is equivalent to get_type().get_index().

Definition at line 52 of file typedObject.I.

References TypeHandle::get_index().

bool EggBackPointer::has_vertices ( ) const [virtual, inherited]

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 in EggJointNodePointer, and EggVertexPointer.

Definition at line 60 of file eggBackPointer.cxx.

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 EggJointNodePointer, and EggMatrixTablePointer.

Definition at line 58 of file eggJointPointer.h.

bool TypedObject::is_exact_type ( TypeHandle  handle) const [inline, inherited]
bool TypedObject::is_of_type ( TypeHandle  handle) const [inline, inherited]

Returns true if the current object is or derives from the indicated type.

Definition at line 63 of file typedObject.I.
