Detailed Description

A specific kind of CullBin that sorts geometry in the order specified by the user-specified draw_order parameter.

This allows precise relative ordering of two objects.

When two or more objects are assigned the same draw_order, they are drawn in scene-graph order (as with CullBinUnsorted).

Member Function Documentation

void CullBinFixed::add_object (  CullableObject *  object  )  [virtual]

Adds a geom, along with its associated state, to the bin for rendering. Implements CullBin. Definition at line 61 of file cullBinFixed.cxx. References _objects.

void CullBinFixed::draw (   )  [virtual]

Draws all the geoms in the bin, in the appropriate order. Implements CullBin. Definition at line 98 of file cullBinFixed.cxx.

void CullBinFixed::finish_cull (   )  [virtual]

Called after all the geoms have been added, this indicates that the cull process is finished for this frame and gives the bins a chance to do any post-processing (like sorting) before moving on to draw. Reimplemented from CullBin. Definition at line 83 of file cullBinFixed.cxx.

virtual TypeHandle CullBinFixed::force_init_type (  void   )  [inline, virtual]

Reimplemented from CullBin. Definition at line 88 of file cullBinFixed.h.

TypeHandle CullBinFixed::get_class_type (  void   )  [inline, static]

Reimplemented from CullBin. Definition at line 77 of file cullBinFixed.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 CullBinFixed::get_type (  void   )  const [inline, virtual]

Reimplemented from CullBin. Definition at line 85 of file cullBinFixed.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 CullBinFixed::init_type (  void   )  [inline, static]

Reimplemented from CullBin. Definition at line 80 of file cullBinFixed.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. Definition at line 86 of file typedObject.I. Referenced by EggMaterialCollection::collapse_equivalent_materials(), EggTextureCollection::collapse_equivalent_textures(), DeferredNodeProperty::compose(), AnimBundleMaker::create_s_channel(), CharacterMaker::create_slider(), ProjectionScreen::cull_callback(), DataNode::define_output(), EggNode::determine_draw_order(), CharacterMaker::egg_to_index(), EggGroupUniquifier::EggGroupUniquifier(), EggPoolUniquifier::EggPoolUniquifier(), EggGroupNode::find_textures(), StaticTextFont::get_glyph(), EggMaterialCollection::insert_materials(), EggTextureCollection::insert_textures(), CharacterJoint::make_copy(), PT(), EggGroupNode::r_flatten_transforms(), EggGroupNode::r_transform_vertices(), EggGroupNode::recompute_polygon_normals(), CollisionLevelState::reserve(), PandaFramework::reset_frame_rate(), PandaFramework::set_texture(), EggGroupNode::steal_children(), and DataGraphTraverser::traverse().

PointerTo< CullBin > CullBin::make_next (   )  const [virtual, inherited]

Returns a newly-allocated CullBin object that contains a copy of just the subset of the data from this CullBin object that is worth keeping around for next frame. If a particular CullBin object has no data worth preserving till next frame, it is acceptable to return NULL (which is the default behavior of this method). Definition at line 64 of file cullBin.cxx.

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().

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. Definition at line 293 of file referenceCount.I. References INLINE. Referenced by RenderState::determine_bin_index(), and RenderEffects::determine_show_bounds().
