Detailed Description

The CullingKit class is a user space object, useful for carrying a group attribute settings. Calling CullingKit::GetDefault() will return a kit with values found in this table.

Constructor & Destructor Documentation

CullingKit::CullingKit ( )

Initializes an empty kit.

CullingKit::CullingKit ( CullingKit const &  in_kit)

The copy constructor creates a new CullingKit object that contains the same settings as the source object.

Parameters
in_kitThe source object to copy.
CullingKit::CullingKit ( CullingKit &&  in_that)

The move constructor creates a CullingKit by transferring the underlying impl of the rvalue reference to this CullingKit thereby avoiding a copy and allocation.

Parameters
in_thatAn rvalue reference to a CullingKit to take the impl from.
virtual CullingKit::~CullingKit ( )
virtual

Destroy this kit.

Member Function Documentation

bool CullingKit::Empty ( ) const
virtual

Indicates whether this object has any values set on it.

Returns
true if no values are set on this object, false otherwise.

Reimplemented from Object.

bool CullingKit::Equals ( CullingKit const &  in_kit) const

Check if the source CullingKit is equivalent to this object.

Parameters
in_kitThe source CullingKit to compare to this object.
Returns
true if the objects are equivalent, false otherwise.
static CullingKit CullingKit::GetDefault ( )
static

Creates a CullingKit which contains the default settings. The returned object will not necessarily have values set for every option, but it will have settings for those options where it is reasonable to have a default.

Returns
A CullingKit with the default settings.
Type CullingKit::ObjectType ( ) const
inlinevirtual

This function returns the type the object, as declared. This does not necessarily give the true type of the underlying object.

Returns
The declared type of the object in question, which may differ from the true, underlying type.

Reimplemented from Object.

bool CullingKit::operator!= ( CullingKit const &  in_kit) const

Check if the source CullingKit is not equivalent to this object.

Parameters
in_kitThe source CullingKit to compare to this object.
Returns
true if the objects are not equivalent, false otherwise.
CullingKit& CullingKit::operator= ( CullingKit &&  in_that)

The move assignment operator transfers the underlying impl of the rvalue reference to this CullingKit thereby avoiding a copy.

Parameters
in_thatAn rvalue reference to a CullingKit to take the impl from.
Returns
A reference to this CullingKit.
CullingKit& CullingKit::operator= ( CullingKit const &  in_kit)

Copies the source CullingKit into this object.

Parameters
in_kitThe source CullingKit to copy.
Returns
A reference to this object.
bool CullingKit::operator== ( CullingKit const &  in_kit) const

Check if the source CullingKit is equivalent to this object.

Parameters
in_kitThe source CullingKit to compare to this object.
Returns
true if the objects are equivalent, false otherwise.
void CullingKit::Set ( CullingKit const &  in_kit)

Parameters
in_stateWhether faces with normals that point away from the camera should be culled.
Returns
A reference to this object.
CullingKit& CullingKit::SetDeferralExtent ( bool  in_state,
unsigned int  in_pixels

in_stateWhether deferral culling should be enabled.
in_pixelsThe number of pixels below which geometry should be culled with deferral.
Returns
A reference to this object.
CullingKit& CullingKit::SetDeferralExtent ( unsigned int  in_pixels)

Controls whether geometry that falls below a certain size in pixels should be culled with deferral. Deferral culling means the object is given a low-priority draw order, effectively delaying draw time until the end of the frame. This function implicitly enables deferral extent culling.

Parameters
in_pixelsThe number of pixels below which geometry should be culled with deferral.
Returns
A reference to this object.

in_stateWhether extent culling should be enabled.
in_pixelsThe longest dimension of the screen-space projection of the bounding-volume, in pixels.
Returns
A reference to this object.
CullingKit& CullingKit::SetExtent ( unsigned int  in_pixels)

Controls whether geometry that falls below a certain size in pixels should be culled. This function implicitly enables extent culling.

Parameters
in_pixelsThe longest dimension of the screen-space projection of the bounding-volume, in pixels.
Returns
A reference to this object.
CullingKit& CullingKit::SetFrustum ( bool  in_state)

Controls whether geometry outside the current view frustum should be culled.

Parameters

Returns
A reference to this object.
CullingKit& CullingKit::SetVector ( bool  in_state,
Vector const &  in_vector,
float  in_tolerance_degrees
