void PointParticleRenderer::kill_particle (  int  index  )  [private, virtual]

child kill Implements BaseParticleRenderer. Definition at line 169 of file pointParticleRenderer.cxx. References _blend_method, BaseParticleRenderer::PP_BLEND_CUBIC, and PP_BLEND_VEL.

BaseParticleRenderer * PointParticleRenderer::make_copy (  void   )  [virtual]

for spawning systems from dead particles Implements BaseParticleRenderer. Definition at line 95 of file pointParticleRenderer.cxx. References _color_array, _max_pool_size, _point_primitive, and _vertex_array.

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.

renders the particle system out to a GeomNode Definition at line 252 of file pointParticleRenderer.cxx. References _aabb_max, and _aabb_min.

void PointParticleRenderer::resize_pool (  int  new_size  )  [private, virtual]

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().
