Detailed Description

A special binner used only within this package to pre-process the egg tree for the loader and group things together as appropriate.

Presently, it only groups related LOD children together under a single LOD node.

bool EggBinner::collapse_group ( const EggGroup * group,

int bin_number

) [virtual]

May be overridden in derived classes to specify whether a particular group node, apparently redundant, may be safely collapsed out.

Reimplemented from EggBinMaker.
Definition at line 83 of file eggBinner.cxx.

virtual TypeHandle EggBinMaker::force_init_type ( void ) [inline, virtual, inherited]

Reimplemented from EggObject.
Definition at line 320 of file eggBinMaker.h.

string EggBinMaker::get_bin_name ( int bin_number ) [virtual, inherited]

May be overridden in derived classes to define a name for each new bin, based on its bin number.

Definition at line 168 of file eggBinMaker.cxx.

int EggBinner::get_bin_number ( const EggNode * node ) [virtual]

Implements EggBinMaker.
Definition at line 36 of file eggBinner.cxx.

TypeHandle EggBinMaker::get_class_type ( void ) [inline, static, inherited]

Reimplemented from EggObject.
Definition at line 309 of file eggBinMaker.h.

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

Returns the current reference count.

Definition at line 183 of file referenceCount.I.
Referenced by RenderState::determine_bin_index(), RenderEffects::determine_show_bounds(), FontPool::ns_garbage_collect(), TexturePool::ns_garbage_collect(), MaterialPool::ns_get_material(), and TexturePool::ns_release_texture().

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

Reimplemented from EggObject.
Definition at line 317 of file eggBinMaker.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().
Definition at line 71 of file typedObject.I.
References TypeHandle::get_name(), TypedObject::get_type(), and INLINE.

void EggBinMaker::init_type ( void ) [inline, static, inherited]

Reimplemented from EggObject.
Definition at line 312 of file eggBinMaker.h.

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

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

Definition at line 101 of file typedObject.I.
Referenced by PT(), and CollisionNode::xform().

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

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

int EggBinMaker::make_bins ( EggGroupNode * root_group ) [inherited]

The main entry point to EggBinMaker.
Walks the egg scene graph beginning at the indicated root node, and moves all binnable nodes into EggBin objects. Returns the number of EggBins created.
Definition at line 101 of file eggBinMaker.cxx.
Referenced by EggLoader::EggLoader().

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.
Definition at line 225 of file referenceCount.I.
Referenced by ClientDevice::ClientDevice(), EggGroupNode::find_textures(), EggGroupNode::r_apply_texmats(), EggGroupNode::r_flatten_transforms(), and EggGroupNode::reverse_vertex_ordering().

bool EggBinner::sorts_less ( int bin_number,

const EggNode * a,

const EggNode * b

) [virtual]

May be overridden in derived classes to create additional bins within a particular bin number, based on some arbitrary property of nodes.
This function establishes an arbitrary but fixed ordering between nodes; if two nodes do not sort to the same position, different bins are created for each one (with the same bin number on each bin).
Reimplemented from EggBinMaker.
Definition at line 56 of file eggBinner.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.
The return value is the new reference count.
