Detailed Description

Being rendered, the elements modifies current model-view matrix such that the axes of the specified reference system (in model space) become oriented in the following way:

Constructor & Destructor Documentation

◆ OpenGl_Flipper()

OpenGl_Flipper::OpenGl_Flipper ( const gp_Ax2 theReferenceSystem)

Construct rendering element to flip model-view matrix along the reference system to ensure up-Y, right-X orientation.

Parameters
theReferenceSystem[in] the reference coordinate system.

Member Function Documentation

◆ DumpJson()

virtual void OpenGl_Flipper::DumpJson ( Standard_OStream theOStream,
Standard_Integer  theDepth = -1 
) const
overridevirtual

Dumps the content of me into the stream.

Reimplemented from OpenGl_Element.

◆ Release()

virtual void OpenGl_Flipper::Release ( OpenGl_Context theContext)
overridevirtual

Release GPU resources. Pointer to the context is used because this method might be called when the context is already being destroyed and usage of a handle would be unsafe.

Implements OpenGl_Element.

◆ Render()

virtual void OpenGl_Flipper::Render ( const Handle< OpenGl_Workspace > &  theWorkspace) const
overridevirtual

Implements OpenGl_Element.

◆ SetOptions()

void OpenGl_Flipper::SetOptions ( const Standard_Boolean  theIsEnabled)
inline

Set options for the element.

Parameters
theIsEnabled[in] flag indicates whether the flipper matrix modification should be set up or restored back.
