deferred generic class PSurfaceTool from IntImp
(Surface as any)
---Purpose: Template class for a tool on a bi-parametrised surface.
-- It is possible to implement this tool with an
-- instantiation of the SurfaceTool from Adaptor3d.
uses Pnt from gp,
Vec from gp
is
UIntervalFirst(myclass ; S: Surface)
---Purpose: Returns the first U parameter of the surface.
returns Real from Standard;
VIntervalFirst(myclass ; S: Surface)
---Purpose: Returns the first V parameter of the surface.
returns Real from Standard;
UIntervalLast(myclass ; S: Surface)
---Purpose: Returns the last U parameter of the surface.
returns Real from Standard;
VIntervalLast(myclass ; S: Surface)
---Purpose: Returns the last V parameter of the surface.
returns Real from Standard;
Value (myclass ; S: Surface; U,V : Real from Standard)
---Purpose: Returns the point of parameter (U,V) on the surface.
returns Pnt from gp;
D1(myclass; S: Surface; U,V: Real from Standard;
P: out Pnt from gp; D1U,D1V: out Vec from gp);
---Purpose: Returns the point of parameter (U,V) on the surface,
-- and the first derivatives in the directions u and v.
UResolution(myclass; S : Surface; Tol3d: Real from Standard)
---Purpose: Returns the numerical resolution in the U direction,
-- for a given resolution in 3d space.
returns Real from Standard;
VResolution(myclass; S : Surface; Tol3d: Real from Standard)
---Purpose: Returns the numerical resolution in the V direction,
-- for a given resolution in 3d space.
returns Real from Standard;
