<font face="Myriad Pro">Dear list,<br>
<br>
i am messing around how to make the right angle symbol from _pst-eucl_
look much better in a 2D projection of a 3D arrangement...<br>
<br>
Shouldn't it be elliptic there instead of a part of a circle to show
the 3D effect. I know that is not the idea of _pst-eucl_. However i had
no other idea to adjust the right angle better than with _pst-eucl_.<br>
There is no will to act in 3D coordinates. Just the idea for the
projection and better looking.<br>
<br>
Any ideas how to refine the following right angle symbols to show the
3D character of the graphic a bit better in 2D?<br>
