◆ SetIsForHighlight()

void Graphic3d_Structure::SetIsForHighlight ( const Standard_Boolean isForHighlight )

marks the structure <me> representing wired structure needed for highlight only so it won't be added to BVH tree. Category: Methods to modify the class definition

◆ SetMutable()

void Graphic3d_Structure::SetMutable ( const Standard_Boolean theIsMutable )

Sets if the structure location has mutable nature (content or location will be changed regularly).

◆ SetOwner()

void Graphic3d_Structure::SetOwner ( const Standard_Address Owner )

◆ SetTransformation()

void Graphic3d_Structure::SetTransformation ( const Handle< Geom_Transformation > & theTrsf )

Modifies the current local transformation.

◆ SetTransformPersistence()

void Graphic3d_Structure::SetTransformPersistence ( const Handle< Graphic3d_TransformPers > & theTrsfPers )

Modifies the current transform persistence (pan, zoom or rotate)

◆ SetVisible()

void Graphic3d_Structure::SetVisible ( const Standard_Boolean AValue )

Modifies the visibility indicator to Standard_True or Standard_False for the structure <me>. The default value at the definition of <me> is Standard_True.

◆ SetVisual()

virtual void Graphic3d_Structure::SetVisual ( const Graphic3d_TypeOfStructure AVisual )

virtual

Modifies the visualisation mode for the structure <me>.

◆ SetZLayer()

void Graphic3d_Structure::SetZLayer ( const Graphic3d_ZLayerId theLayerId )

Set Z layer ID for the structure. The Z layer mechanism allows to display structures presented in higher layers in overlay of structures in lower layers by switching off z buffer depth test between layers.

◆ SetZoomLimit()

void Graphic3d_Structure::SetZoomLimit	(	const Standard_Real	LimitInf,
		const Standard_Real	LimitSup
	)

Modifies the minimum and maximum zoom coefficients for the structure <me>. The default value at the definition of <me> is unlimited. Category: Methods to modify the class definition Warning: Raises StructureDefinitionError if <LimitInf> is greater than <LimitSup> or if <LimitInf> or <LimitSup> is a negative value.

◆ Standard_DEPRECATED()

Graphic3d_Structure::Standard_DEPRECATED ( "This method is deprecated - SetTransformation() should be called instead" ) const &

inline

◆ Transformation()

const Handle< Geom_Transformation >& Graphic3d_Structure::Transformation ( ) const

inline

Return local transformation.

◆ TransformBoundaries()

static void Graphic3d_Structure::TransformBoundaries	(	const gp_Trsf &	theTrsf,
		Standard_Real &	theXMin,
		Standard_Real &	theYMin,
		Standard_Real &	theZMin,
		Standard_Real &	theXMax,
		Standard_Real &	theYMax,
		Standard_Real &	theZMax
	)

staticprotected

Transforms boundaries with <theTrsf> transformation.

◆ TransformPersistence()

const Handle< Graphic3d_TransformPers >& Graphic3d_Structure::TransformPersistence ( ) const

inline

Returns: transform persistence of the presentable object.

◆ Transforms()

static void Graphic3d_Structure::Transforms	(	const gp_Trsf &	theTrsf,
		const Standard_Real	theX,
		const Standard_Real	theY,
		const Standard_Real	theZ,
		Standard_Real &	theNewX,
		Standard_Real &	theNewY,
		Standard_Real &	theNewZ
	)

static

Transforms theX, theY, theZ with the transformation theTrsf.

◆ UnHighlight()

void Graphic3d_Structure::UnHighlight ( )

Suppresses the highlight for the structure <me> in all the views of the visualiser.

◆ Visual()

Graphic3d_TypeOfStructure Graphic3d_Structure::Visual ( ) const

Returns the visualisation mode for the structure <me>.
