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 only x-lines, forming the surface mesh, are displayed.
The same model in JavaView.
Note: in JavaView we can display mesh as a whole or not display it at all. Therefore, partial mesh cannot be displayed.
