I tried to make some experiment with 3dplot, and I found a strange thing :
According to the doc, the kernel of the "3dto2d" transform matrice should be
   [\sin(\Alpha)*\cos(\Beta) ;\cos(\Alpha)*\cos(\Beta);\sin(\Beta) ]
So, when I test the following :
\def\al{60}\def\be{130} %just because I can't use \Alpha and \Beta !



I expect that the 3DLine is reduced to a point (the origin).
But it's not the case and I'm wondering why !
