Detailed Description

The smallest atom of cull.

This is normally just a Geom and its associated state, but it also contain a draw callback.

Constructor & Destructor Documentation

◆ CullableObject() [1/3]

CullableObject::CullableObject ( )

inline

Creates an empty CullableObject whose pointers can be filled in later.

Definition at line 18 of file cullableObject.I.

◆ CullableObject() [2/3]

CullableObject::CullableObject	(	CPT(Geom)	geom,
		CPT(RenderState)	state,
		CPT(TransformState)	internal_transform
	)

inline

Creates a CullableObject based the indicated geom, with the indicated render state and transform.

Definition at line 29 of file cullableObject.I.

◆ CullableObject() [3/3]

CullableObject::CullableObject ( const CullableObject & copy )

inline

Copies the CullableObject.

Member Function Documentation

◆ draw()

void CullableObject::draw	(	GraphicsStateGuardianBase *	gsg,
		bool	force,
		Thread *	current_thread
	)

inline

Draws the cullable object on the GSG immediately, in the GSG's current state.

This should only be called from the draw thread.

Definition at line 72 of file cullableObject.I.

References GeomDrawCallbackData::get_lost_state().

◆ draw_callback()

void CullableObject::draw_callback	(	GraphicsStateGuardianBase *	gsg,
		bool	force,
		Thread *	current_thread
	)

inline

Invokes the draw callback, assuming one is set.

Crashes if not.

◆ draw_inline()

void CullableObject::draw_inline	(	GraphicsStateGuardianBase *	gsg,
		bool	force,
		Thread *	current_thread
	)

inline

Draws the cullable object on the GSG immediately, in the GSG's current state.

This should only be called from the draw thread. Assumes the GSG has already been set to the appropriate state.

Definition at line 132 of file cullableObject.I.

◆ flush_level()

void CullableObject::flush_level ( )

inlinestatic

Flushes the PStatCollectors used during traversal.

Definition at line 122 of file cullableObject.I.

◆ munge_geom()

bool CullableObject::munge_geom	(	GraphicsStateGuardianBase *	gsg,
		GeomMunger *	munger,
		const CullTraverser *	traverser,
		bool	force
	)

Uses the indicated GeomMunger to transform the geom and/or its vertices.

If force is false, this may do nothing and return false if the vertex data is nonresident. If force is true, this will always return true, but it may have to block while the vertex data is paged in.

Definition at line 54 of file cullableObject.cxx.

◆ operator=()

void CullableObject::operator= ( const CullableObject & copy )

inline

Copies the CullableObject.

Definition at line 59 of file cullableObject.I.

◆ request_resident()

bool CullableObject::request_resident ( ) const

inline

Returns true if all the data necessary to render this object is currently resident in memory.

If this returns false, the data will be brought back into memory shortly; try again later.

Definition at line 97 of file cullableObject.I.

◆ set_draw_callback()

void CullableObject::set_draw_callback ( CallbackObject * draw_callback )

inline

Specifies a CallbackObject that will be responsible for drawing this object.

Definition at line 114 of file cullableObject.I.
