Convert NFF to PLY

The Neutral File Format (NFF) is a minimal scene description language used in computer graphics for testing rendering algorithms and efficiency schemes. Developed in the 1990s, NFF provides a structured way to define 3D geometric objects, surface properties, lighting placement, and viewing angles. It is primarily utilized in ray tracing applications and procedural databases, enabling interoperability between different rendering systems. While originally designed for algorithm evaluation, NFF has influenced the development of more advanced scene description formats. Its simplicity and ASCII-based structure make it a practical choice for quick data exchange in 3D modeling environments.

The Polygon File Format (PLY) is a versatile file format designed for storing 3D polygonal models. It originated at Stanford University in the mid-1990s to support the Stanford 3D Scanning Repository project. The primary purpose of PLY is to efficiently represent and exchange three-dimensional data, including vertex coordinates, colors, and normals. Its flexibility makes it valuable for various applications such as 3D scanning, computer graphics, and 3D printing. PLY files can store both ASCII and binary data, making them adaptable for diverse processing needs within computer technology.
