This project was an introduction to “events” programming basically was about creating a simplified graphic “wireframe” (“fils de fer” in French, hence the name of the project) representation of a relief landscape linking various points (x, y, z) via segments. The coordinates of this landscape are stored in a file passed as a parameter to the executable.
In this project i discovered the basics of graphic programming, and in particular how to place points in space, how to join them with segments, and most importantly how to observe the scene from a particular viewpoint.
Here is an example:
$ make
$ ./fdf test_maps/chose_any_map
