Detailed Description

A specific kind of CullBin that sorts geometry in order from nearest to furthest based on the center of its bounding volume.

This is useful for rendering opaque geometry, taking optimal advantage of a hierarchical Z-buffer.

Member Function Documentation

void CullBinFrontToBack::add_object	(	CullableObject *	object,
		Thread *	current_thread
	)		[virtual]

Adds a geom, along with its associated state, to the bin for rendering.

Implements CullBin.

Definition at line 59 of file cullBinFrontToBack.cxx.

void CullBinFrontToBack::draw	(	bool	force,
		Thread *	current_thread
	)		[virtual]

Draws all the geoms in the bin, in the appropriate order.

Implements CullBin.

Definition at line 100 of file cullBinFrontToBack.cxx.

void CullBinFrontToBack::fill_result_graph

(

CullBin::ResultGraphBuilder &

builder

)

[protected, virtual]

Called by CullBin::make_result_graph() to add all the geoms to the special cull result scene graph.

Implements CullBin.

Definition at line 116 of file cullBinFrontToBack.cxx.

References CullBin::ResultGraphBuilder::add_object().

void CullBinFrontToBack::finish_cull	(	SceneSetup *	scene_setup,
		Thread *	current_thread
	)		[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 88 of file cullBinFrontToBack.cxx.

static void CullBinFrontToBack::init_type

(

)

[inline, static]

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from CullBin.

Definition at line 70 of file cullBinFrontToBack.h.

References CullBin::init_type().

CullBin * CullBinFrontToBack::make_bin	(	const string &	name,
		GraphicsStateGuardianBase *	gsg,
		const PStatCollector &	draw_region_pcollector
	)		[static]

Factory constructor for passing to the CullBinManager.
