Member Function Documentation

void OpenGl_Layer::Add	(	const OpenGl_Structure *	theStruct,
		const Standard_Integer	thePriority,
		Standard_Boolean	isForChangePriority = `Standard_False`
	)

Standard_Boolean OpenGl_Layer::Append ( const OpenGl_Layer & theOther )

Append layer of acceptable type (with similar number of priorities or less). Returns Standard_False if the list can not be accepted.

const OpenGl_ArrayOfIndexedMapOfStructure& OpenGl_Layer::ArrayOfStructures ( ) const

inline

Returns array of OpenGL structures.

Bnd_Box OpenGl_Layer::BoundingBox	(	const Standard_Integer	theViewId,

Parameters

theViewId	view index to consider View Affinity in structure
theCamera	camera definition
theWindowWidth	viewport width (for applying transformation-persistence)
theWindowHeight	viewport height (for applying transformation-persistence)
theToIncludeAuxiliary	consider also auxiliary presentations (with infinite flag or with trihedron transformation persistence)

Returns: computed bounding box

Standard_Boolean OpenGl_Layer::IsImmediate ( ) const

inline

Return true if layer was marked with immediate flag.

const Graphic3d_ZLayerSettings& OpenGl_Layer::LayerSettings ( ) const

inline

Returns settings of the layer object.

Standard_Integer OpenGl_Layer::NbOfTransformPersistenceObjects ( ) const
