42-FdF

FDF is short for ’fil de fer’ in French which means ’wireframe model’. image

This is the first graphical project from the 42 curriculum and requires the use of the MiniLibx library. This library was developed by 42 School and includes the necessary tools to open a window, create images and deal with keyboard and mouse events.

The main goal of this project is to create a wireframe model representation of a 3D landscape given by a .fdf file.

Extra features that are triggered by the keyboard:

  • Translation of the model.
  • Rotations.
  • Zoom in and out.
  • Top view.
  • Scale height representation.
  • Change between diferent color gradients.

Rendering

The program first represents the model in isometric projection and with a color gradient associated to the altitude.
The coordinates of the landscape are stored in a .fdf file passed as a parameter to the program.
Each number represents a point in space:

  • The horizontal position corresponds to its axis.
  • The vertical position corresponds to its ordinate.
  • The value corresponds to its altitude.
  • Some points can have a color defined in hex notation , ex.: 3,0xFF0000 represents a point with height 3 and the color white.

Requirements (Linux)

MiniLibx

  • MinilibX only supports TrueColor visual type (8,15,16,24 or 32 bits depth)
  • gcc
  • make
  • X11 include files (package xorg)
  • XShm extension must be present (package libxext-dev)
  • Utility functions from BSD systems - development files (package libbsd-dev)

How to use

sudo apt-get install gcc make xorg libxext-dev libbsd-dev

git clone

make

(choose a map)
./fdf maps/(map).fdf
