This project is about creating a simplified graphic wireframe representation of a relief landscape linking various points (x, y, z) via segments using Bresenham's algorithm. The coordinates of this landscape are stored in a map-file passed as a parameter to program.

some maps may contain a color codes
You can find examples in the maps folder. Use ready maps or create your own using a map-generator
There are basics of graphic programming in this project, and in particular how to place points in space, how to join them with segments and how to observe the scene from a particular viewpoint.
miniLibX - is a graphic library, wich was developed internally in Ecole42 and includes the minimum necessary to open a window, light a pixel and deal with events linked to this window: keyboard and mouse.
