FDF - fil de fer (french for Wire)
This project is an introduction to 3D drawing. It takes a map file and render it with its height. It listen to keyboard event to apply transformations on it, such as translation, rotations, zoom, and change in altitude factor.
the input map is a simple text file that looks like this :
$> cat -e map_test.fdf
0 0 0 0 0$
0 0 0 0 0$
0 10 0 0 0$
0 0 0 0 0$
0 0 0 0 0$
$>
and the program converts it into a rectangular net, like a landscape with the height equal to the numbers :
we can modify the map to see a new 3D model :
$> cat -e map_test.fdf
0 0 0 0 0$
1 2 3 4 5$
0 10 8 0 0$
0 0 0 9 0$
0 0 0 0 0$
