# FDF | 3D Wireframe Viewer | 42Paris

## Introduction

The program takes a 2D map as a parameter and creates its 3D projection. The column is the x, the line is the y and the value is the z.

## Implementation

Here is a summary of how the overal program works:

- Parsing: the map which is presented as a file is read line by line and the values are parsed and stored into the following data structure where x, y, z and color values are the directly taken from the map:

-       typedef struct s_array{

              double	x;

              double	y;

              double	z;

              int		color;

              int		x_screen;

              int		y_screen;

              int		max_color;

            }				t_array;

- Then matrix-vector multiplication of the x, y and z with the rotation matrix is used to calculate the x_screen and y_screen at every point. For this application we chose to initialize the rotation matrix to: roll = 0.523599, pitch = -0.523599, yaw = 0.523599. you can modify these angles accordingly they will represent the first view of the map. 

- Bresenham's Line Drawing Algorithm is used to draw lines between every two points. 

- Hooks:

  - Rotation: You can rotate the view using the keys D (roll -), A (roll +), W (picth +), X (pitch -), Z (yaw -), and E (yaw +).

  - Zoom: Zoom in and out of the map as needed.

  - Altitude Adjustment: Fine-tune the altitude scale coefficient using the up and down arrow keys.

  - Color Variation: The map's colors dynamically change based on its altitude.

## Usage

One of the requirement of this project was to use 42l's minilibX. 

- This project is designed to work with minilibx for linux version make sure you have the minilibx-linux version in the repo.

- git clone https://github.com/shimazadeh/FDF.git FDF

- cd FDF

- make

- ./fdf maps/test_maps/map.fdf
