AIS_Shape Class Reference

A framework to manage presentation and selection of shapes. AIS_Shape is the interactive object which is used the most by applications. There are standard functions available which allow you to prepare selection operations on the constituent elements of shapes - vertices, edges, faces etc - in an open local context. The selection modes specific to "Shape" type objects are referred to as Standard Activation Mode. These modes are only taken into account in open local context and only act on Interactive Objects which have redefined the virtual method AcceptShapeDecomposition so that it returns true. Several advanced functions are also available. These include functions to manage deviation angle and deviation coefficient - both HLR and non-HLR - of an inheriting shape class. These services allow you to select one type of shape interactive object for higher precision drawing. When you do this, the Prs3d_Drawer::IsOwn... functions corresponding to the above deviation angle and coefficient functions return true indicating that there is a local setting available for the specific object.

Detailed Description

A framework to manage presentation and selection of shapes. AIS_Shape is the interactive object which is used the most by applications. There are standard functions available which allow you to prepare selection operations on the constituent elements of shapes - vertices, edges, faces etc - in an open local context. The selection modes specific to "Shape" type objects are referred to as Standard Activation Mode. These modes are only taken into account in open local context and only act on Interactive Objects which have redefined the virtual method AcceptShapeDecomposition so that it returns true. Several advanced functions are also available. These include functions to manage deviation angle and deviation coefficient - both HLR and non-HLR - of an inheriting shape class. These services allow you to select one type of shape interactive object for higher precision drawing. When you do this, the Prs3d_Drawer::IsOwn... functions corresponding to the above deviation angle and coefficient functions return true indicating that there is a local setting available for the specific object.

Constructor & Destructor Documentation

AIS_Shape::AIS_Shape ( const TopoDS_Shape shap)

Initializes construction of the shape shap from wires, edges and vertices.

Member Function Documentation

virtual Standard_Boolean AIS_Shape::AcceptShapeDecomposition ( ) const
overridevirtual

Returns true if the Interactive Object accepts shape decomposition.

Reimplemented from AIS_InteractiveObject.

virtual const Bnd_Box& AIS_Shape::BoundingBox ( )
virtual

Constructs a bounding box with which to reconstruct compound topological shapes for presentation.

virtual Quantity_NameOfColor AIS_Shape::Color ( ) const
overridevirtual

Returns the NameOfColor attributes of the shape accordingly to the current facing model;.

Reimplemented from AIS_InteractiveObject.

virtual void AIS_Shape::Color ( Quantity_Color aColor) const
overridevirtual

Returns the Color attributes of the shape accordingly to the current facing model;.

Reimplemented from AIS_InteractiveObject.

virtual void AIS_Shape::Compute ( const Handle< PrsMgr_PresentationManager3d > &  aPresentationManager,
const Handle< Prs3d_Presentation > &  aPresentation,
const Standard_Integer  aMode = 0 
)
overrideprotectedvirtual

Calculates the 3D view aPresentation and its updates. The latter are managed by aPresentationManager. aPresentableObject has the display mode aMode; this has the default value of 0, that is, the wireframe display mode.

Reimplemented from PrsMgr_PresentableObject.

Reimplemented in AIS_TexturedShape, AIS_ColoredShape, and XCAFPrs_AISObject.

virtual void AIS_Shape::Compute ( const Handle< Prs3d_Projector > &  aProjector,
const Handle< Prs3d_Presentation > &  aPresentation 
)
overrideprotectedvirtual

Calculates the 3D view aPresentation and its updates. The latter are managed by aPresentationManager. Each of the views in the viewer and every modification such as rotation, for example, entails recalculation. It must be redefined to implement hidden line removal for the object. The user never calls this method himself. This is done via the InteractiveContext object and is dependent on the point of view from which the object is displayed.

Reimplemented from PrsMgr_PresentableObject.

virtual void AIS_Shape::Compute ( const Handle< Prs3d_Projector > &  aProjector,
const Handle< Geom_Transformation > &  aTrsf,
const Handle< Prs3d_Presentation > &  aPresentation 
)
overrideprotectedvirtual

Calculates the 3D view aPresentation and its updates. The latter are managed by aPresentationManager. A point of view is provided by the projector aProjector, and the geometric transformation which has transformed associated presentable objects is specified by aTrsf. This function is to be used in case where a hidden line removal display cannot be calculated automatically. This occurs when associated presentable objects have been transformed geometrically, but not translated. Warning The transformation aTrsf must be applied to the object before computation.

Reimplemented from PrsMgr_PresentableObject.

virtual void AIS_Shape::ComputeSelection ( const Handle< SelectMgr_Selection > &  aSelection,
const Standard_Integer  aMode 
)
overrideprotectedvirtual

Recovers and calculates any sensitive primitive, aSelection, available in Shape mode, specified by aMode. As a rule, these are sensitive faces. This method is defined as virtual. This enables you to implement it in the creation of a new class of AIS Interactive Object. You need to do this and in so doing, redefine this method, if you create a class which enriches the list of signatures and types.

Implements SelectMgr_SelectableObject.

void AIS_Shape::LoadRecomputable ( const Standard_Integer  TheMode)

Standard_Boolean AIS_Shape::OwnDeviationCoefficient ( Standard_Real aCoefficient,
Standard_Real aPreviousCoefficient 
) const

Returns true and the values of the deviation coefficient aCoefficient and the previous deviation coefficient aPreviousCoefficient. If these values are not already set, false is returned.

Standard_Boolean AIS_Shape::OwnHLRDeviationAngle ( Standard_Real anAngle,

Returns true and the values of the HLR deviation angle anAngle and of the previous HLR deviation angle aPreviousAngle. If these values are not already set, false is returned.

Standard_Boolean AIS_Shape::OwnHLRDeviationCoefficient ( Standard_Real aCoefficient,
Standard_Real aPreviousCoefficient 
) const

static Standard_Integer AIS_Shape::SelectionMode ( const TopAbs_ShapeEnum  aShapeType)

Establishes an equivalence between a mode and the type, aShapeType, of selection. The correspondences are as follows:

  • mode 0 - Shape
  • mode 1 - Vertex
  • mode 2 - Edge
  • mode 3 - Wire
  • mode 4 - Face
  • mode 5 - Shell
  • mode 6 - Solid
  • mode 7 - Compsolid
  • mode 8 - Compound
static TopAbs_ShapeEnum AIS_Shape::SelectionType ( const Standard_Integer  aDecompositionMode)
