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.
Image obtained in MuPAD. In this plot we do not plot the mesh.
The same model in JavaView. In JavaView displaying mesh lines can be turned off. Therefore, both MuPAD plot as well as JavaView model are identical.
