 ~SelectMgr_TriangularFrustumSet () 

virtual void  Build (const TColgp_Array1OfPnt2d &thePoints) Standard_OVERRIDE 
 Meshes polygon bounded by polyline. Than organizes a set of triangular frustums, where each triangle's projection onto near and far view frustum planes is considered as a frustum base. More...


virtual NCollection_Handle< SelectMgr_BaseFrustum >  ScaleAndTransform (const Standard_Integer theScale, const gp_Trsf &theTrsf) Standard_OVERRIDE 
 Returns a copy of the frustum with all subvolumes transformed according to the matrix given. More...


virtual Standard_Boolean  Overlaps (const SelectMgr_Vec3 &theMinPnt, const SelectMgr_Vec3 &theMaxPnt, Standard_Real &theDepth) Standard_OVERRIDE 
 SAT intersection test between defined volume and given axisaligned box. More...


virtual Standard_Boolean  Overlaps (const SelectMgr_Vec3 &theMinPnt, const SelectMgr_Vec3 &theMaxPnt, Standard_Boolean *theInside) Standard_OVERRIDE 
 Returns true if selecting volume is overlapped by axisaligned bounding box with minimum corner at point theMinPt and maximum at point theMaxPt. More...


virtual Standard_Boolean  Overlaps (const gp_Pnt &thePnt, Standard_Real &theDepth) Standard_OVERRIDE 
 Intersection test between defined volume and given point. More...


virtual Standard_Boolean  Overlaps (const Handle< TColgp_HArray1OfPnt > &theArrayOfPnts, Select3D_TypeOfSensitivity theSensType, Standard_Real &theDepth) Standard_OVERRIDE 
 SAT intersection test between defined volume and given ordered set of points, representing line segments. The test may be considered of interior part or boundary line defined by segments depending on given sensitivity type. More...


virtual Standard_Boolean  Overlaps (const gp_Pnt &thePnt1, const gp_Pnt &thePnt2, Standard_Real &theDepth) Standard_OVERRIDE 
 Checks if line segment overlaps selecting frustum. More...


virtual Standard_Boolean  Overlaps (const gp_Pnt &thePnt1, const gp_Pnt &thePnt2, const gp_Pnt &thePnt3, Select3D_TypeOfSensitivity theSensType, Standard_Real &theDepth) Standard_OVERRIDE 
 SAT intersection test between defined volume and given triangle. The test may be considered of interior part or boundary line defined by triangle vertices depending on given sensitivity type. More...


 SelectMgr_BaseFrustum () 
 Creates new selecting volume with pixel toletance set to 2, orthographic camera and empty frustum builder. More...


virtual  ~SelectMgr_BaseFrustum () 

void  SetCamera (const Handle< Graphic3d_Camera > &theCamera) 
 Passes camera projection and orientation matrices to builder. More...


void  SetCamera (const Graphic3d_Mat4d &theProjection, const Graphic3d_Mat4d &theOrientation, const Standard_Integer theIsOrthographic) 
 Passes camera projection and orientation matrices to builder. More...


void  SetPixelTolerance (const Standard_Integer theTol) 

void  SetWindowSize (const Standard_Integer theWidth, const Standard_Integer theHeight) 

void  SetViewport (const Standard_Real theX, const Standard_Real theY, const Standard_Real theWidth, const Standard_Real theHeight) 
 Passes viewport parameters to builder. More...


void  SetBuilder (const Handle< SelectMgr_FrustumBuilder > &theBuilder) 
 Nullifies the builder created in the constructor and copies the pointer given. More...


virtual void  Build (const gp_Pnt2d &) 
 Builds volume according to the point and given pixel tolerance. More...


virtual void  Build (const gp_Pnt2d &, const gp_Pnt2d &) 
 Builds volume according to the selected rectangle. More...


virtual void  Build (const gp_Pnt2d &, const gp_Pnt2d &, const gp_Pnt2d &) 
 Builds volume according to the triangle given. More...


virtual Standard_Boolean  Overlaps (const gp_Pnt &thePnt) 
 Intersection test between defined volume and given point Does not perform depth calculation, so this method is defined as helper function for inclusion test. Therefore, its implementation makes sense only for rectangular frustum with box selection mode activated. More...


virtual Standard_Real  DistToGeometryCenter (const gp_Pnt &theCOG) 
 Measures distance between 3d projection of userpicked screen point and given point theCOG. More...


virtual gp_Pnt  DetectedPoint (const Standard_Real theDepth) const 

virtual Standard_Boolean  IsClipped (const Graphic3d_SequenceOfHClipPlane &thePlanes, const Standard_Real theDepth) 
 Checks if the point of sensitive in which selection was detected belongs to the region defined by clipping planes. More...
