Class Function3d is the most fundamental class for producing graphs of functions of two variables. JavaView models obtained by transforming Function3d plots are identical with images that we produce in MuPAD.
In this example the function of two variables was declared as a procedure producing values calculated while developing Julia fractal. For each pair (x,y) the value f(x,y) is equal to the number of iterations of the Julia fractal for the given point (x,y).
Image obtained in MuPAD.
The same model in JavaView.
