``Re: pictures'' by Dr_Absentius on 2003-01-29 12:10:32
yeah,I know about xeukleides and I use it some times. What I like about
Dr_Genius though is that it is interactive: you can change one structural element and everything else changes with it. For example you can move one point and watch how Desargues' line change, etc.

Although Dr_Genius has GUI the input is very structured: you input lines by determining two points, you can specify a point as the intersection of two lines etc.
