This project is about representing a landscape as a 3D object in which all surfaces are outlined in lines.
The perpose of the project was to read point coordenates from a file, and then throught the use of the school's library MiniLibX, draw the map froma specific viewpoint
The file would look something like this
$>cat 42.fdf

Each number represents a point in space:
• The horizontal position corresponds to its axis.
• The vertical position corresponds to its ordinate.
• The value corresponds to its altitude.
And the program would have to create a window and print the image like so
Some files also come with color hexadecimal value of the points

The intra folder is the one that was delivered but it only works on mac
git clone https://github.com/20AAP02/42_Fdf.git
cd 42_Fdf/fdf_dir
In mac
make
In linux
make l
./fdf maps/test_maps/42.fdf
There's many files you can use. You can also add your own files as long they are .fdf and have the same format
Once the window is opened, you can use:
• "+ -" to zoom in and out.
• "z x" to change scale of the points altitude.
• "a d / arrows" to move the picture left and right.
• "w s / arrows" to move the picture up and down.
• "b" to change to black and white
• "SPACE" to eliminate the colores that came with the map
