PLY
PLY 3D File
PLY is a polygon file format primarily used to store three-dimensional data from 3D scanners.
What is PLY 3D File?
The PLY format, also known as the Polygon File Format or Stanford Triangle Format, was developed in the 1990s at Stanford University by Greg Turk and others. It is designed specifically to store digital data derived from 3D scanners, supporting a relatively simple description of a single object as a list of nominally flat polygons. It exists in both ASCII (text) and binary forms, making it flexible for data exchange, and can store properties such as color, transparency, surface normals, and texture coordinates.
Advantages
- Supports both ASCII and binary encodings
- Stores vertex colors, normals, and texture coordinates
- Widely supported by 3D scanning and processing software
- Simple structure makes custom parsers easy to write
Limitations
- ASCII files can be very large in size
- Lacks support for hierarchical scenes and complex animations
- Not optimized for real-time web rendering without conversion
