In the rapidly evolving world of digital data, encountering various file formats is a daily occurrence. One such format that users often struggle with is the .PLY file. Whether you are a developer, a designer, or a casual user, understanding how to handle 3D Image files is essential. This comprehensive guide will walk you through everything you need to know about the PLY extension, its uses, and how to open it using Blender, MeshLab.
1. Detailed Technical Overview
PLY is a computer file format known as the Polygon File Format or the Stanford Triangle Format. It stores 3D data from 3D scanners.
The .PLY file is categorized under 3D Image. These files are structured to store specific data types efficiently. Unlike standard text files, a .PLY file requires a specific interpretation mechanism, which is usually provided by the primary software, Blender, MeshLab.
