Detailed Description

Filter of TKOpenGl elements for processing only shading geometry and for collecting number of skipped elements to an external counter.

Constructor & Destructor Documentation

OpenGl_OpaqueFilter()

OpenGl_LayerList::OpenGl_OpaqueFilter::OpenGl_OpaqueFilter ( )

inline

Constructor.

Parameters

thePrevFilter

[in] the previously active filter that should have additive effect.

Member Function Documentation

NbSkipped()

Standard_Size OpenGl_LayerList::OpenGl_OpaqueFilter::NbSkipped ( ) const

inline

Returns number of skipped elements.

SetPreviousFilter()

void OpenGl_LayerList::OpenGl_OpaqueFilter::SetPreviousFilter ( const Handle< OpenGl_RenderFilter > &  thePrevFitler )

inline

Sets the current active filter in workspace.

Parameters

thePrevFilter

[in] the previously active filter that should have additive effect.

SetSkippedCounter()

void OpenGl_LayerList::OpenGl_OpaqueFilter::SetSkippedCounter ( const Standard_Size  theCounter )

inline

Sets the value of the skipped elements counter.

ShouldRender()

virtual Standard_Boolean OpenGl_LayerList::OpenGl_OpaqueFilter::ShouldRender ( const Handle< OpenGl_Workspace > &  theWorkspace, const OpenGl_Element *  theGlElement  )

overridevirtual

Checks whether the element should be rendered or skipped.

Parameters

theWorkspace	[in] the currently used workspace for rendering.
theGlElement	[in] the TKOpenGl rendering queue element that should be checked before streaming to GPU.

Implements OpenGl_RenderFilter.
