Examples:
x1^2+x1*x3+13*x2^2+x3-1=0;
x1+x2+x3=0;


 x1^2+0.1*x2^2+x3^2-9=0;
 x1+3*x3+1=0;


 x1^2-0.1*x2^2+x3^2-9=0;

equidistant_curve_MP.mw  Equidistant curves to the curves on the surface. (Without any sense, but real.)







     Example of the equidistant surface at a distance of 0.25 to the surface
x3
-0.1 * (sin (4 * x1) + sin (3 * x2 + x3) + sin (2 * x2)) = 0
Constructed on the basis of universal parameterization of surfaces.
