Detailed Description

The smallest atom of cull.

This is normally just a Geom and its associated state, but it also represent a number of Geoms to be drawn together, with a number of Geoms decalled onto them.

Constructor & Destructor Documentation

CullableObject::CullableObject (  CullableObject *  next = NULL  )  [inline]

Creates an empty CullableObject whose pointers can be filled in later. Definition at line 33 of file cullableObject.I. References INLINE.

CullableObject::CullableObject (  const CullTraverserData &  data, GeomNode *  geom_node, int  i, CullableObject *  next = NULL )  [inline]

Creates a CullableObject based on the ith Geom from the indicated GeomNode, with the render state from the indicated CullTraverserData. Definition at line 51 of file cullableObject.I. References INLINE.

CullableObject::CullableObject (  Geom *  geom, const RenderState *  state, const TransformState *  transform, CullableObject *  next = NULL )  [inline]

Creates a CullableObject based the indicated geom, with the indicated render state and transform. Definition at line 72 of file cullableObject.I. References INLINE, and NULL.

CullableObject::CullableObject (  const CullableObject &  copy  )  [inline]

Copies the CullableObject, but does not copy its children (decals). Definition at line 94 of file cullableObject.I. References _next, INLINE, and NULL.

CullableObject::~CullableObject (   )

Automatically deletes the whole chain of these things. Definition at line 38 of file cullableObject.cxx. References _geom, and NULL.

Definition at line 88 of file cullableObject.h.

int CullableObject::get_num_ever_allocated (   )  [inline, static]

Returns the number of CullableObject pointers ever simultaneously allocated; these are now either in active use or have been recycled into the deleted CullableObject pool to be used again. Definition at line 197 of file cullableObject.I.

bool CullableObject::has_decals (   )  const [inline]

Returns true if the object has one or more decals placed on it, false otherwise. Definition at line 130 of file cullableObject.I. References _deleted_chain, _next, and INLINE. Referenced by CullResult::add_object().

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

Definition at line 91 of file cullableObject.h.

void CullableObject::operator delete (  void *  ptr  )  [inline]

Frees the memory for a deleted CullableObject. This is specialized here to provide for fast allocation of these things (since we may create and destroy thousands of these each frame). Definition at line 176 of file cullableObject.I.

void * CullableObject::operator new (  size_t  size  )  [inline]

Allocates the memory for a new CullableObject. This is specialized here to provide for fast allocation of these things (since we may create and destroy thousands of these each frame). Definition at line 149 of file cullableObject.I. References _num_ever_allocated, and INLINE.

void CullableObject::operator= (  const CullableObject &  copy  )  [inline]

Copies the CullableObject, but does not copy its children (decals). Definition at line 113 of file cullableObject.I. References _deleted_chain, _next, _num_ever_allocated, INLINE, NULL, and operator new().

void CullableObject::output (  ostream &  out  )  const

Definition at line 53 of file cullableObject.cxx.
