Standard_EXPORT | AIS_MidPointRelation (const TopoDS_Shape &aSymmTool, const TopoDS_Shape &FirstShape, const TopoDS_Shape &SecondShape, const Handle(Geom_Plane)&aPlane) |
virtual Standard_Boolean | IsMovable () const |
Returns true if the interactive object is movable. . | |
void | SetTool (const TopoDS_Shape &aMidPointTool) |
const TopoDS_Shape & | GetTool () const |
virtual Standard_EXPORT void | Compute (const Handle(Prs3d_Projector)&aProjector, const Handle(Geom_Transformation)&aTrsf, const Handle(Prs3d_Presentation)&aPresentation) |
Computes the presentation according to a point of view given by <aprojector>. To be Used when the associated degenerated Presentations have been transformed by <atrsf> which is not a Pure Translation. The HLR Prs can't be deducted automatically WARNING :<atrsf> must be applied to the object to display before computation !!! . | |

Private Member Functions | |
Standard_EXPORT void | Compute (const Handle(PrsMgr_PresentationManager3d)&aPresentationManager, const Handle(Prs3d_Presentation)&aPresentation, const Standard_Integer aMode=0) |
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. . | |
Standard_EXPORT void | Compute (const Handle(Prs3d_Projector)&aProjector, const Handle(Prs3d_Presentation)&aPresentation) |
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. . | |
Standard_EXPORT void | Compute (const Handle(PrsMgr_PresentationManager2d)&aPresentationManager, const Handle(Graphic2d_GraphicObject)&aPresentation, const Standard_Integer aMode=0) |
Calculates the 2D 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. Note that this syntax is not used in AIS as that package only concerns 3D display. . | |
Standard_EXPORT void | ComputeSelection (const Handle(SelectMgr_Selection)&aSelection, const Standard_Integer aMode) |
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. . | |
Standard_EXPORT void | ComputeFaceFromPnt (const Handle(Prs3d_Presentation)&aprs, const Standard_Boolean first) |
Standard_EXPORT void | ComputeEdgeFromPnt (const Handle(Prs3d_Presentation)&aprs, const Standard_Boolean first) |
Standard_EXPORT void | ComputeVertexFromPnt (const Handle(Prs3d_Presentation)&aprs, const Standard_Boolean first) |
Standard_EXPORT void | ComputePointsOnLine (const gp_Lin &aLin, const Standard_Boolean first) |
Standard_EXPORT void | ComputePointsOnLine (const gp_Pnt &pnt1, const gp_Pnt &pnt2, const Standard_Boolean first) |
Standard_EXPORT void | ComputePointsOnCirc (const gp_Circ &aCirc, const gp_Pnt &pnt1, const gp_Pnt &pnt2, const Standard_Boolean first) |
Standard_EXPORT void | ComputePointsOnElips (const gp_Elips &anEll, const gp_Pnt &pnt1, const gp_Pnt &pnt2, const Standard_Boolean first) |
ComputePointsOn... methods set myFAttach, myFirstPnt and myLastPnt from the following initial data: curve, end points, myMidPoint. End points (pnt1 & pnt2) and curve define the trimmed curve. If end points are equal, curve is not trimmed (line - special case). .------. pnt2 / \ . circle . myLastPnt | | . pnt1 . myFAttach \ arc / . myMidPoint .______. myFirstPnt . | |
