# FDF - fil de fer

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

it reads a map, which is a simple text file like this :

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

we can modify the map to change the 3D drawing :

then it listen to keyboards events to transform the 3D, like turning around, zooming... :

**zoom :**

**turn :**

**move :**

**change height :**
