Member Function Documentation

◆ applyMaskAction()

void osg::CullSettings::applyMaskAction ( unsigned int maskBit )

inline

Apply the action, specified by the InheritanceMaskActionOnAttributeSetting, to apply to the inheritance bit mask.

This method is called by CullSettings::set*() parameter methods to ensure that CullSettings inheritance mechanisms doesn't overwrite the local parameter settings.

◆ getClampProjectionMatrixCallback() [1/2]

ClampProjectionMatrixCallback* osg::CullSettings::getClampProjectionMatrixCallback ( )

inline

get the non const ClampProjectionMatrixCallback.

◆ getClampProjectionMatrixCallback() [2/2]

const ClampProjectionMatrixCallback* osg::CullSettings::getClampProjectionMatrixCallback ( ) const

inline

get the const ClampProjectionMatrixCallback.

◆ getCullingMode()

CullingMode osg::CullSettings::getCullingMode ( ) const

inline

Returns the current CullingMode.

◆ getDepthSortImpostorSprites()

bool osg::CullSettings::getDepthSortImpostorSprites ( ) const

inline

Get whether ImpostorSprite's are depth sorted bin for rendering.

◆ getImpostorPixelErrorThreshold()

float osg::CullSettings::getImpostorPixelErrorThreshold ( ) const

inline

Get the impostor error threshold.

◆ getImpostorsActive()

bool osg::CullSettings::getImpostorsActive ( ) const

inline

Get whether impostors are active or not.

◆ getInheritanceMask()

InheritanceMask osg::CullSettings::getInheritanceMask ( ) const

inline

Get the inheritance mask used in inheritCullSettings to control which variables get overwritten by the passed in CullSettings object.

◆ getLODScale()

float osg::CullSettings::getLODScale ( ) const

inline

Get the LOD bias.

◆ getNumberOfFrameToKeepImpostorSprites()

int osg::CullSettings::getNumberOfFrameToKeepImpostorSprites ( ) const

inline

Get the number of frames that an ImpostorSprite is kept whilst not being beyond, before being recycled.

◆ getSmallFeatureCullingPixelSize()

float osg::CullSettings::getSmallFeatureCullingPixelSize ( ) const

inline

Get the Small Feature Culling Pixel Size.

◆ inheritCullSettings() [1/2]

virtual void osg::CullSettings::inheritCullSettings ( const CullSettings & settings )

inlinevirtual

Inherit the local cull settings variable from specified CullSettings object, according to the inheritance mask.

Reimplemented in osgUtil::SceneView.

◆ inheritCullSettings() [2/2]

virtual void osg::CullSettings::inheritCullSettings	(	const CullSettings &	settings,
		unsigned int	inheritanceMask
	)

virtual

Inherit the local cull settings variable from specified CullSettings object, according to the inheritance mask.

Reimplemented in osg::Camera, and osgUtil::SceneView.

◆ readCommandLine()

void osg::CullSettings::readCommandLine ( ArgumentParser & arguments )

read the commandline arguments.

◆ readEnvironmentalVariables()

void osg::CullSettings::readEnvironmentalVariables ( )

read the environmental variables.

◆ setClampProjectionMatrixCallback()

void osg::CullSettings::setClampProjectionMatrixCallback ( ClampProjectionMatrixCallback * cpmc )

inline

set the ClampProjectionMatrixCallback.

◆ setCullingMode()

void osg::CullSettings::setCullingMode ( CullingMode mode )

inline

Set the culling mode for the CullVisitor to use.

◆ setCullSettings()

void osg::CullSettings::setCullSettings ( const CullSettings & settings )

Set the local cull settings values from specified CullSettings object.

◆ setDepthSortImpostorSprites()

void osg::CullSettings::setDepthSortImpostorSprites ( bool doDepthSort )

inline

Set whether ImpostorSprite's should be placed in a depth sorted bin for rendering.

◆ setImpostorPixelErrorThreshold()

void osg::CullSettings::setImpostorPixelErrorThreshold ( float numPixels )

inline

Set the impostor error threshold.

Used in calculation of whether impostors remain valid.

◆ setImpostorsActive()

void osg::CullSettings::setImpostorsActive ( bool active )

inline

Switch the creation of Impostors on or off.

Setting active to false forces the CullVisitor to use the Impostor LOD children for rendering. Setting active to true forces the CullVisitor to create the appropriate pre-rendering stages which render to the ImpostorSprite's texture.

◆ setInheritanceMask()

void osg::CullSettings::setInheritanceMask ( InheritanceMask mask )

inline

Set the inheritance mask used in inheritCullSettings to control which variables get overwritten by the passed in CullSettings object.

◆ setLODScale()

void osg::CullSettings::setLODScale ( float scale )

inline

Set the LOD bias for the CullVisitor to use.

◆ setNumberOfFrameToKeepImpostorSprites()

void osg::CullSettings::setNumberOfFrameToKeepImpostorSprites ( int numFrames )

inline

Set the number of frames that an ImpostorSprite is kept whilst not being beyond, before being recycled.

◆ setSmallFeatureCullingPixelSize()

void osg::CullSettings::setSmallFeatureCullingPixelSize ( float value )

inline

Threshold at which small features are culled.

Parameters

value Bounding volume size in screen space. Default is 2.0.

◆ write()

void osg::CullSettings::write ( std::ostream & out )

Write out internal settings of CullSettings.
