FdF: Fil de Fer (Wireframe)

A 3D wireframe renderer built in C, capable of transforming 2D coordinate grids into immersive 3D landscapes. This project explores the fundamentals of Linear Algebra, Isometric Projections, and the Bresenham Line Algorithm.

Technical Highlights

• Coordinate Transformation: Implements rotation matrices and isometric projection formulas to map 3D points ($x, y, z$) onto a 2D screen ($x', y'$).
• Bresenham's Algorithm: Optimized line drawing to connect vertices with smooth, alias-free segments.
• Memory management: Robust parsing of .fdf files, handling massive corrdinate grids without memory leaks.
• Real-time interaction: Fast rendering loop using MiniLibX to allow fluid transformations.

The Math Behind the Projection

To achieve the "iron wire" look, the engine applies an isometric transformation where the angles between the $x, y,$ and $z$ axes are all equal ($120^\circ$):

$$x_{iso} = (x - y) \cdot \cos(0.523599)$$
$$y_{iso} = (x + y) \cdot \sin(0.523599) - z$$
