virtual void Clear (const Standard_Boolean WithDestruction=Standard_True)
 if WithDestruction == Standard_True then suppress all the groups of primitives in the structure. and it is mandatory to create a new group in <me>. if WithDestruction == Standard_False then clears all the groups of primitives in the structure. and all the groups are conserved and empty. They will be erased at the next screen update. The structure itself is conserved. The transformation and the attributes of <me> are conserved. The childs of <me> are conserved. More...

inline

Sets infinite flag. When TRUE, the MinMaxValues method returns: theXMin = theYMin = theZMin = RealFirst(). theXMax = theYMax = theZMax = RealLast(). By default, structure is created not infinite but empty.

◆ SetIsForHighlight()

void Graphic3d_Structure::SetIsForHighlight ( const Standard_Boolean  isForHighlight)
inline

Marks the structure <me> representing wired structure needed for highlight only so it won't be added to BVH tree.

◆ SetMutable()

void Graphic3d_Structure::SetMutable ( const Standard_Boolean  theIsMutable)
inline

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

◆ SetOwner()

void Graphic3d_Structure::SetOwner ( const Standard_Address  theOwner)
inline

◆ SetTransformation()

void Graphic3d_Structure::SetTransformation ( const Handle< TopLoc_Datum3D > &  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.

◆ Transformation()

const Handle< TopLoc_Datum3D >& 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
inline

Returns the visualisation mode for the structure <me>.
