FDF Project - "Bringing 3D Landscapes to Life"

Project Overview

This project involves creating a 3D wireframe model of a landscape from a grid of points using the MiniLibX graphical library. The goal was to render a 3D landscape in isometric projection based on data provided in a .fdf file, which contains a matrix of altitude points.

Design and Development

1. File Parsing

The input is an .fdf file with a matrix of numbers representing the height of each point in the landscape. I implemented file reading using get_next_line, and parsed the numbers into a 2D array using ft_split.

2. Isometric Projection

I used isometric projection to convert 3D points (x, y, z) into 2D coordinates for rendering. The projection gives the illusion of depth, making the 3D wireframe appear in a 2D window.

3. Rendering with MiniLibX

Each point in the 3D model is connected by lines to its neighbors, forming a grid-like wireframe. I used MiniLibX to open a window and draw the lines between points.

4. Window Management

The program opens a window where the landscape is displayed. I added event handling to:

• Close the window when the ESC key is pressed.
• Ensure the window closes properly when the user clicks the close button.

Key Challenges

• File Parsing: Ensuring that the input file is read correctly and handling any formatting issues.
• Memory Management: Preventing memory leaks by freeing all dynamically allocated memory.
• Projection and Rendering: Properly mapping 3D coordinates to a 2D plane for smooth rendering.

Bonus Part

For the bonus, I added:

• Zoom: Allowing the user to zoom in and out of the 3D model.
• Translation: Enabling the user to move the model within the window.

How to Compile and Run

Compilation

To compile the project:

make

Running the Program

To run the program:

./fdf [file.fdf]

Example:

./fdf example.fdf

This runs the program using a .fdf file, rendering the 3D landscape in an isometric view.
