DN (myclass; S : HSurface; U, V : Real; IU, IV : Integer) returns Vec; Continuity(myclass; S : HSurface) returns Integer; ---Purpose: returns the order of continuity of the HSurface . -- returns 1 : first derivative only is computable -- returns 2 : first and second derivative only are computable. Bounds(myclass; S : HSurface; U1, V1, U2, V2 : out Real); ---Purpose: returns the bounds of the HSurface. end SurfaceTool;
