FDF - fil de fer

this program is written in C

this is an exercize to discover 3D drawing, keyboard events, and pixel images manipulation

what it does is to read a map, which is a simple text file like this one :

0  0  0  0  0
0  0  0  0  0
0 10  0  0  0
0  0  0  0  0
0  0  0  0  0

and it will convert it into a rectangular net, like a landscape with the height equal to the numbers :

if we modify the map it will modify the 3D drawing
