In this example we use 10 randomly located circles in 3D with common center. The radius and color of each circle is also random.
Image obtained in MuPAD.
The same model in JavaView.
NOTE: in this example it is important to have Z-buffer turned on. If for some reason xvc2jvx will not produce Z-buffer on, this sometimes happens, then turn it on by hand in JavaView in the Display panel.
