Black Rectangles on Pixelated Image about asymptote

1. From the documentation:
   If your video card generates unwanted black stripes in the output, try setting the
   horizontal and vertical components of the setting maxtile to something less than your screen dimensions.

2. For vector graphics you need to remove the line settings.prc = false;
   That will generated 3D PRC vector graphics, embedded within a PDF file. However, since
   Adobe Reader doesn't remesh on zooming, strictly speaking Adobe Reader isn't a vector graphics viewer.
   True (OpenGL) vector graphics is obtained by deleting the line settings.outformat = "pdf".
