class Sphere from Bnd
---Purpose: This class represents a bounding sphere of a geometric entity
-- (triangle, segment of line or whatever else).
uses XYZ from gp
is
Create returns Sphere;
---Purpose: Empty constructor
Create (theCntr : XYZ from gp; theRad : Real; theU : Integer; theV : Integer)
returns Sphere;
---Purpose: Constructor of a definite sphere
U (me) returns Integer;
---C++: inline
---Purpose: Returns the U parameter on shape
V (me) returns Integer;
---C++: inline
---Purpose: Returns the V parameter on shape
IsValid (me) returns Boolean;
---C++: inline
---Purpose: Returns validity status, indicating that this
-- sphere corresponds to a real entity
SetValid (me : in out; isValid : Boolean);
---C++: inline
Center (me) returns XYZ from gp;
---C++: inline
---C++: return const &
---Purpose: Returns center of sphere object
Radius (me) returns Real;
---C++: inline
---Purpose: Returns the radius value
Distances (me; theXYZ : XYZ from gp; theMin : in out Real; theMax : in out Real) is static;
---Purpose: Calculate and return minimal and maximal distance to sphere.
-- NOTE: This function is tightly optimized; any modifications
-- may affect performance!
SquareDistances (me; theXYZ : XYZ from gp; theMin : in out Real; theMax : in out Real) is static;
---Purpose: Calculate and return minimal and maximal distance to sphere.
-- NOTE: This function is tightly optimized; any modifications
-- may affect performance!
Project (me; theNode : XYZ from gp; theProjNode : in out XYZ from gp; theDist : in out Real; theInside : in out Boolean)
---Purpose: Projects a point on entity.
-- Returns true if success
returns Boolean;
Distance (me; theNode : XYZ from gp)
returns Real;
SquareDistance (me; theNode : XYZ from gp)
returns Real;
Add (me : in out; theOther : Sphere from Bnd);
IsOut (me; theOther : Sphere from Bnd)
returns Boolean;
IsOut (me; thePnt : XYZ from gp; theMaxDist : in out Real)
returns Boolean;
SquareExtent (me) returns Real;
