Member Function Documentation

void OpenGl_LayerList::AddLayer

(

const Graphic3d_ZLayerId

theLayerId

)

Insert a new layer with id.

void OpenGl_LayerList::AddStructure	(	const OpenGl_Structure *	theStruct,

		const Graphic3d_ZLayerId	theNewLayerId
	)

Change structure z layer If the new layer is not presented, the structure will be displayed in default z layer.

void OpenGl_LayerList::ChangePriority	(	const OpenGl_Structure *	theStructure,
		const Graphic3d_ZLayerId	theLayerId,
		const Standard_Integer	theNewPriority
	)

Changes structure priority within its ZLayer.
