Hi all !

I'm searching for a *FAST* clipping algorithm, because I'm writing
an animated Vektorgraphic in assembler, and I want to clip all lines
which go out of the screen :

For example :

   Such a line          Should be Clipped to :
         \
   _______\______            ______________
   I       \    I            I       \    I
   I        \   I            I        \   I
   I         \  I            I         \  I
   I          \ I            I          \ I
   ------------\-            --------------
                \
                 \

Any suggestions ?

Please reply directly to me, the I-AMIGA-link to europe is down.
