class Plane from StdPrs
inherits Root from Prs3d
---Purpose: A framework to display infinite planes.
uses
Surface from Adaptor3d,
Presentation from Prs3d,

Length from Quantity
is
Add(myclass; aPresentation: Presentation from Prs3d;
aPlane : Surface from Adaptor3d;
aDrawer : Drawer from Prs3d);
---Purpose: Defines display of infinite planes.
-- The infinite plane aPlane is added to the display
-- aPresentation, and the attributes of the display are
-- defined by the attribute manager aDrawer.
Match(myclass; X,Y,Z : Length from Quantity;
aDistance: Length from Quantity;
aPlane : Surface from Adaptor3d;
aDrawer : Drawer from Prs3d)
returns Boolean from Standard;
---Purpose: returns true if the distance between the point (X,Y,Z) and the
-- plane is less than aDistance.
