In this example we use a few 2D classes in order to see how they will be transformed into JavaView. Note - in JavaView we do not have rectangle, circle or ellipse. Therefore, these objects will be presented using polygons. The edges of polygons may have influence the final result.
Image obtained in MuPAD. Here, of course, the transparency is not displayed.
The same model in JavaView. We obtained here the transparency as well as some unwanted effects. The ellipse shows edges of its components.
