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 void  SetViewClipping (const Graphic3d_SequenceOfHClipPlane &) 
 Valid for point selection only! Computes depth range for global (defined for the whole view) clipping planes. More...
