 SelectMgr_Frustum () 

 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_Real 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 &)

virtual NCollection_Handle
< SelectMgr_BaseFrustum >  Transform (const gp_Trsf &) 

virtual NCollection_Handle
< SelectMgr_BaseFrustum >  Scale (const Standard_Real) 
 IMPORTANT: Makes sense only for frustum built on a single point! Returns a copy of the frustum resized according to the scale factor given. More...


virtual Standard_Boolean  Overlaps (const BVH_Box< Standard_Real, 3 > &theBndBox, Standard_Real &theDepth) 
 SAT intersection test between defined volume and given axisaligned box. More...


virtual Standard_Boolean  Overlaps (const SelectMgr_Vec3 &theBoxMin, const SelectMgr_Vec3 &theBoxMax, Standard_Boolean *theInside=NULL) 
 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 &thePt, Standard_Real &theDepth) 
 Intersection test between defined volume and given point. More...


virtual Standard_Boolean  Overlaps (const Handle< TColgp_HArray1OfPnt > &theArrayOfPts, Select3D_TypeOfSensitivity theSensType, Standard_Real &theDepth) 
 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...
