Detailed Description

These are the vertices that must be animated as part of the normal character animation.

This includes vertices animated into one or more joints, as well as morph vertices.

Member Function Documentation

int TypedWritable::complete_pointers ( TypedWritable ** p_list,

BamReader * manager

) [virtual, inherited]

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Returns the number of pointers processed.
This is the callback function that is made by the BamReader at some later point, after all of the required pointers have been filled in. It is necessary because there might be forward references in a bam file; when we call read_pointer() in fillin(), the object may not have been read from the file yet, so we do not have a pointer available at that time. Thus, instead of returning a pointer, read_pointer() simply reserves a later callback. This function provides that callback. The calling object is responsible for keeping track of the number of times it called read_pointer() and extracting the same number of pointers out of the supplied vector, and storing them appropriately within the object.
Reimplemented in AnimBundleNode, AnimGroup, PartBundleNode, PartGroup, Character, CharacterJoint, CollisionNode, GeomSprite, PiecewiseCurve, ClipPlaneAttrib, FogAttrib, LensNode, LightAttrib, MaterialAttrib, RenderEffects, RenderState, TextureAttrib, Person, and Child.

void ComputedVertices::fillin ( DatagramIterator & scan,

BamReader * manager

) [protected]

Function that reads out of the datagram (or asks manager to read) all of the data that is needed to re-create this object and stores it in the appropiate place.

Reimplemented from TypedWritable.
Definition at line 409 of file computedVertices.cxx.

void TypedWritable::finalize ( void ) [virtual, inherited]

Called by the BamReader to perform any final actions needed for setting up the object after all objects have been read and all pointers have been completed.

Reimplemented in PartBundle, RenderAttrib, RenderEffect, RenderEffects, RenderState, and TransformState.
Definition at line 112 of file typedWritable.cxx.

virtual TypeHandle ComputedVertices::get_type ( void ) const [inline, virtual]

Reimplemented from TypedWritableReferenceCount.
Definition at line 104 of file computedVertices.h.

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().

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

Reimplemented from TypedWritableReferenceCount.

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

Returns true if the current object is the indicated type exactly.

TypedWritable * ComputedVertices::make_ComputedVertices ( const FactoryParams & params ) [static]

Factory method to generate a ComputedVertices object.

Definition at line 464 of file computedVertices.cxx.

void ComputedVertices::make_orig ( Character * character )

Copies all the values loaded in the _coords, _norms, etc.
arrays into the corresponding _orig_coords, etc. arrays.
Definition at line 268 of file computedVertices.cxx.
References _orig_texcoords.

int ReferenceCount::ref ( ) const [inline, inherited]

Explicitly increments the reference count.
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is the new reference count.

void ComputedVertices::register_with_read_factory ( void ) [static]

Factory method to generate a ComputedVertices object.

Definition at line 484 of file computedVertices.cxx.

void ReferenceCount::test_ref_count_integrity ( ) const [inline, inherited]

Does some easy checks to make sure that the reference count isn't completely bogus.

Definition at line 328 of file referenceCount.I.
References INLINE.
Referenced by EggNode::determine_bin(), and ReferenceCount::~ReferenceCount().

int ReferenceCount::unref ( ) const [inline, inherited]

Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

Recomputes all of the _coords, _norms, etc.
values based on the values in _orig_coords, _orig_norms, etc., and the current positions of all of the joints.
