class QuadricTool from IntSurf
---Purpose: This class provides a tool on a quadric that can be
-- used to instantiates the Walking algorithmes (see
-- package IntWalk) with a Quadric from IntSurf
-- as implicit surface.
uses Quadric from IntSurf,
Vec from gp
is
Value(myclass; Quad: Quadric from IntSurf;
X, Y, Z: Real from Standard)
---Purpose: Returns the value of the function.
returns Real from Standard;
---C++: inline
Gradient(myclass; Quad: Quadric from IntSurf;
X, Y, Z: Real from Standard ; V : out Vec from gp);
---Purpose: Returns the gradient of the function.
---C++: inline
ValueAndGradient(myclass; Quad: Quadric from IntSurf;
X, Y, Z: Real from Standard;
Val: out Real from Standard; Grad: out Vec from gp);
---Purpose: Returns the value and the gradient.
---C++: inline
Tolerance(myclass; Quad: Quadric from IntSurf )
---Purpose: returns the tolerance of the zero of the implicit function
returns Real from Standard;
