Fdf

Fdf is a project at 42 that aims to create a graphical representation of a terrain in relief using the codan MLX42 library.

Getting Started

To use this program, you need to clone this repository and compile it with make bonus. This will generate an executable file: fdf.

Usage

To use this program in your own project, you need to provide a map file as an argument to the fdf program. The map file must contain a grid of numbers that represent the height of each point. For example:

0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0
0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0
0  0 10 10  0  0 10 10  0  0  0 10 10 10 10 10  0  0  0
0  0 10 10  0  0 10 10  0  0  0  0  0  0  0 10 10  0  0
0  0 10 10  0  0 10 10  0  0  0  0  0  0  0 10 10  0  0
0  0 10 10 10 10 10 10  0  0  0  0 10 10 10 10  0  0  0
0  0  0 10 10 10 10 10  0  0  0 10 10  0  0  0  0  0  0
0  0  0  0  0  0 10 10  0  0  0 10 10  0  0  0  0  0  0
0  0  0  0  0  0 10 10  0  0  0 10 10 10 10 10 10  0  0
0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0
0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0

The program will display the map in a window using a perspective projection and a color gradient according to the height of each point.

You can create your own maps with the .fdf extension or use the default maps that are in the /test_maps folder.

./fdf test_maps/t1.fdf

You can also interact with the map using the keyboard and mouse:

• Use arrow keys to move the map
• Use O and P keys to zoom in and out
• Use Q and W keys to rotate the X axis
• Use A and S keys to rotate the Y axis
• Use Z and X keys to rotate the Z axis
• Use SPACE to change perspective.
• Use C key to change color.
• Use ESC key to exit the program

Requirements

The project has the following requirements:

• The program must use the MLX42 library for graphical output
• The program must use only basic functions from the standard C library (write, malloc, free, open, read, close)
• The program must handle errors properly and not leak memory
• The program must use a Makefile for compilation
