FDF is a 3D wireframe representation program built in C using the MiniLibX graphics library. It takes a map file (a simple text file containing altitude values) and renders it in an isometric projection. The program supports antialiasing, gradient shading, Motion Blur and other graphical enhancements.
- Parallele Projection: Displays a 3D representation of the terrain.
- Antialiasing: Smooths out jagged edges for a cleaner look.
- Gradient Coloring: Applies color gradients based on altitude values.
- Zoom & Rotation: Allows interactive zooming and rotation.
- Map Loading : Allows in app map loading.
- Draw line on/off : Allows you to select if you want line drawing or only points drawing.
- HUD / Buttons : Quick settings buttons, and show some stuff in the data section.
# Clone the repository
git clone https://github.com/PabloBellissant/fdf.git
cd fdf
# Compile the program
make
# Run FDF with a map file
./fdf maps/42.fdf| Key | Action |
|---|---|
| right click + move | Rotate map |
| mouse wheel | Zoom In / Out |
| middle click + move | Translate map |
| left click + move | Select zone |
| Arrow Up / Down | Change height |
| Arrow Left / Right | Change map |
| ESC | Exit the program |
Below is an example of the antialiasing feature in action (look at the lines in detail):

The program applies smooth gradient shading based on altitude values:

The FDF program accepts maps in the following format:
0 0 0 0 0 0 0 0 0 0
0 10 10 10 10 10 10 10 10 0
0 10 20,0xFF0000 15,0xFF0000 12 15,0xFF0000 17,0xFF0000 20,0xFF0000 10 0
0 10 15,0xFF0000 10 12 15,0xFF0000 15,0xFF0000 15,0xFF0000 10 0
0 5 15,0xFF0000 10 12 15,0xFF0000 15,0xFF0000 13 10 0
0 5 10 5 7 12 12 12 10 0
0 5 7 1 2 7 5 5 7 0
0 3 0 0 1 2 2 2 5 0
0 1 0 0 0 0 0 0 3 0
0 0 0 0 0 0 0 0 0 0
Each number represents an altitude value for the corresponding point on the map. the hex code just after represents the color in RRGGBB
