FDF - making elevations maps more beautiful that ever
Covered concepts:
- using a graphics library
- handling windows and images
- handling the user's keyboard and mouse inputs
- line rasterization
- creating a basic GUI
- using matrices for rotations and other transormations!
- creating an isometric porjection
- working with RGB
- banishing segfaults and memory leaks to the nether
FDF (Fil de fer, or wirefram) takes a file which may look like this:

Each number represents the height coordinate of a point at the 2D position in the table. Our task was to translate this into a visual height map. The map above produced the following output:
Each number can also be followed by a color code, and additional color palettes are availble by hitting 'c'.
You can rotate about each axis, translate and scale the map:
