class ViewerSelector3d from StdSelect inherits ViewerSelector from SelectMgr
---Purpose: Selector Usable by Viewers from V3d
--
uses
View from V3d,
Selection from SelectMgr,
Projector from Select3D,
Group from Graphic3d,
Structure from Graphic3d,
Array1OfReal from TColStd,
Array1OfPnt2d from TColgp
is
Create returns mutable ViewerSelector3d from StdSelect;
---Purpose: Constructs an empty 3D selector object.
Create(aProj : Projector from Select3D) returns mutable ViewerSelector3d from StdSelect;
---Purpose: Constructs a 3D selector object defined by the projector aProj.
Convert(me:mutable;aSelection:mutable Selection from SelectMgr)
is redefined static;
---Level: Public
---Purpose: Processes the projection of the sensitive primitives
-- in the active view ; to be done before the selection action...
Set(me:mutable; aSensitivity : Integer) is static;
---Purpose: Sets the sensitivity aSensitivity.
Set(me:mutable; aProj: Projector from Select3D) is static;
---Purpose: Sets the new projector aProj to replace the one used at construction time.
Pick (me : mutable;XPix,YPix:Integer;
aView : View from V3d) is static;
---Level: Public
---Purpose: Picks the sensitive entity at the pixel coordinates of
-- the mouse Xpix and Ypix. The selector looks for touched areas and owners.
Pick (me:mutable;XPMin,YPMin,XPMax,YPMax:Integer;aView:View from V3d) is static;
---Purpose: Picks the sensitive entity according to the minimum
-- and maximum pixel values XPMin, YPMin, XPMax
-- and YPMax defining a 2D area for selection in the 3D view aView.
Pick (me:mutable;Polyline:Array1OfPnt2d from TColgp;aView:View from V3d) is static;
---Level: Public
---Purpose: pick action - input pixel values for polyline selection for selection.

---Purpose: Clears the view aView of sensitive areas found in it.
DisplaySensitive(me:mutable;aView : View from V3d) is static;
--- Purpose: Displays the selection aSel found in the view aView.
