FDF - Wireframe Landscape Renderer

A simple 3D wireframe renderer written in C using MiniLibX. It takes a .fdf file containing heightmap data and turns it into a 3D isometric projection, rendered in a window.

---

🧠 What It Does

• Reads a .fdf file: a grid of altitude values.
• Plots a 3D landscape using line segments between points.
• Displays it using MiniLibX in isometric projection.
• Memory leak-free.

---

⚙️ How to Run

make
./fdf map.fdf

Press ESC or close the window to exit cleanly.

📦 Features

• ✅ Parses valid .fdf files with altitude data
• ✅ Displays the 3D model in isometric view
• ✅ Uses only allowed system + MLX functions
• ✅ Closes cleanly via window or ESC
• ✅ No memory leaks (valgrind clean)

---

🧰 Tech Stack

• Language: C (Norm compliant)
• Graphics: MiniLibX
• Build: Makefile
• Custom utils: libft, ft_printf, get_next_line

---

🏗️ Room for Improvements

• Add projection options (parallel/conic)
• Implement zoom and pan
• Add rotation support
• Improve error handling for malformed files
• Add interactive controls (keyboard/mouse)

---

⚠️ Known Limitations

• Assumes .fdf input is correctly formatted
• No GUI or menu overlays
• Only basic isometric rendering supported
• Not optimized for large maps

📁 Example .fdf File

0 0 0 0
0 10 10 0
0 0 0 0

Each number = elevation. Horizontal = X, vertical = Y, value = Z.
