%% Modify Appearance of Implicit Surface
% Plot the implicit surface  x^2 +y^2 - z^2 = 0. Remove the lines by setting the EdgeColor property to 'none'. Add transparency by setting the FaceAlpha property to a value between 0 and 1.

f = @(x,y,z) x.^2 + y.^2 - z.^2;
fimplicit3(f,'EdgeColor','none','FaceAlpha',.5)
