FdF

École 42 assignment in C - 3D points and lines plotting

About this project

• This is a solo project of École 42
• FdF stands for "Fils de Fer" in French or wireframe in English.
• The objective is to take the map and plot its points and lines in at least 2 types of 3D projection.
• In this project, I set a default projection to isometric projection and if you rotate it, you will get parallel projection.

The map

• The map contain a list of coordinates.
• The horizontal position corresponds to its axis.
• The vertical position corresponds to its ordinate.
• The value corresponds to its altitude.

How to run the program

• (I use MinilibX from the school system and don't have the library in this repo.)
• Run Makefile to create executable "fdf"

   make
  

• Usage

   ./fdf [map]
  

• I included some sample maps in the folder "maps". To run it.

   ./fdf maps/42.fdf
  

Bonus

• The color goes from blue to green according to the magnitude.
• X-axis rotation with key 5 and 8.
• Y-axis rotation with key 4 and 6.
• Z-axis rotation with key 7 and 9.
• Adjust height level with key 2 and 3.
• Zoom in and out with key + and -.
• Move the map with arrow keys.
• The object is default to the center of the viewpoint.
• Also using image instead of pixel in MiniLibX to gain more performance (if you count it as a bonus.)

The algorithm I used

• I used Bresenham's line algorithm for line plotting.
• I used basic trigonometry in 3D rotation.
