deferred generic class ISurfaceTool from IntImp
( ImplicitSurface as any)
---Purpose: Template class for a tool on an
-- implicit surface.
uses Vec from gp
is
Value(myclass; Is: ImplicitSurface;
X, Y, Z: Real from Standard)
---Purpose: Returns the value of the function.
returns Real from Standard;
Gradient(myclass; Is: ImplicitSurface;
X, Y, Z: Real from Standard ; V: out Vec from gp);
---Purpose: Returns the gradient of the function.
ValueAndGradient(myclass; Is: ImplicitSurface;
X, Y, Z: Real from Standard;
Val: out Real from Standard; Grad: out Vec from gp);
---Purpose: Returns the value and the gradient.
Tolerance(myclass; Is: ImplicitSurface )
---Purpose: returns the tolerance of the zero of the implicit function
returns Real from Standard;
