FdF

This project is an implementation of the classic FdF (Fil de Fer) project from 42. It renders a 3D wireframe model of a landscape (or any 3D map) from a file containing height values. The project uses MLX42 for graphical output and includes bonus features such as multiple projection modes, interactive zooming, rotation, and translation.

Overview

3D Visualization:

The program reads a file containing numerical height values and converts them into a 2D wireframe model using isometric projection (and optionally, other projections).

Interactive Transformations:

Users can zoom in/out, rotate, and translate the model via keyboard inputs.

Multiple Projection Modes (Bonus):

Implemented Isometric and Parallel projection

Gradient Coloring:

Lines are colored with a gradient effect based on the z-values, providing a better sense of depth.

Features

File Parsing:

Reads a map file where each number represents a z-value, forming a matrix of points.

Isometric Projection:

Converts 3D coordinates into 2D using an isometric projection formula.

3D Rotation:

Implements full 3D rotations (using rotation matrices around the X, Y, and Z axes) before projecting the points.

Interactive Controls:

• [W, A, S, D] Translation: Move the model around the window
• [Q, E] Rotation: Rotate the model in 3D space
• [K, L] Zoom: Increase/decrease the scale of the model
• [ESC] Exit: Press ESC to close the application
• [B, N] Projection: Change between Isometric and Parallel
• [M] Colors: Switch between 2 types of color pallets
• [R] Reset: Map reset to default values

Usage

Git clone the repository with submodules libft_divinus and MLX_42

git clone --recursive git@github.com:sknefi/FdF.git

Build application

make 

Add binary with map to render

./fdf map.fdf

Some binaries are stored in test_maps/

./fdf test_maps/42.fdf
