FdF (short for 'Fil de Fer', or 'Wireframe' in French) is a simple 3D wireframe renderer written in C. It was my first graphics project at Hive Helsinki, using MinilibX, a simple, low-level graphics library designed for student projects.
FdF renders a 3D wireframe from a heightmap (saved as a .fdf file) and allows the user to manipulate the view.
Example rendering of a wireframe grid representing a 3D height map.
- 3D Wireframe Rendering: Visualizes 3D height maps from input files (examples included in
test_maps/directory) - 3D Translations: Allows users to move, zoom, and adjust the map's altitude scale.
- Reset View: Quickly revert to default zoom and altitude settings.
- Supports moderately sized maps (tested up to 1000x1000), with performance dropping on larger maps.
- C
- MinilibX: A simple, low-level graphical library for X-Window (included in the repo)
- Makefile: For automated building and dependency management.
- Ensure you have the required dependencies for MinilibX:
sudo apt-get install gcc make xorg libxext-dev libbsd-dev(for Debian/Ubuntu)
git clone https://github.com/yourusername/fdf.git
cd fdf
make
./fdf [path_to_fdf_file]- Arrow Keys: Move the image
- W/S: Zoom in/out
- Q/A: Increase/decrease the vertical scale (altitude) of the wireframe.
- SPACE: Reset settings
- ESC: Exit the program
- macOS: Due to untested changes, macOS support is currently unavailable.
- performance drop on larger map: Performance drops on larger maps; I plan to optimize the map loader in the future.
