FDF - fil de fer

this is an exercise 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 converts 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 :

it is based on a library called minilibx, which is like a simplified version of X11

some of the difficulties of this program :

• finding the equations to transform a 2D drawing into a perspective
• drawing a line between two points
• bits manipulation for colors
• organization of the code to take care of all the events and transformations
• building images instead of asking the minilibx library to draw each pixel one by one

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

zoom :

turn :

move :

change height :
