PLY 3D Model (.PLY)
PLY (Polygon File Format or Stanford Triangle Format) is a flexible 3D model format designed for storing data from 3D scanners, supporting per-vertex properties like color, normals, and custom attributes. It was developed at Stanford University and supports both ASCII and binary encoding. PLY is particularly common in 3D scanning, point cloud processing, and computer graphics research.
Advantages of PLY 3D Model
What the PLY format does well, and why you might choose it.
- Flexible per-vertex property system supporting color, normals, and custom attributes
- Both ASCII and binary formats available for readability or compact storage
- Standard format for 3D scanned data and point cloud datasets
Limitations of PLY 3D Model
What the PLYformat doesn't do well, and when to choose another format.
- No support for textures, materials, animation, or scene hierarchy
- Less widely supported by game engines and web 3D viewers than OBJ or glTF
- No standard compression, leading to large files for dense meshes
What PLY files are used for
- 3D scanning output and point cloud data storage
- Computer graphics research and academic datasets
- Photogrammetry and LIDAR data processing

Frequently asked questions about PLY
What is a .PLY file?
PLY (Polygon File Format or Stanford Triangle Format) is a flexible 3D model format designed for storing data from 3D scanners, supporting per-vertex properties like color, normals, and custom attributes. It was developed at Stanford University and supports both ASCII and binary encoding. PLY is particularly common in 3D scanning, point cloud processing, and computer graphics research.
What is the MIME type of PLY?
The official MIME type for PLY files is application/x-ply. This is the value web servers and applications use to identify the format when transferring files.
What category does PLY belong to?
PLY is a 3D Model Converter format. Files in this category share common conversion paths and use cases.
How do I open a .PLY file?
PLY files are typically opened by software that natively supports the PLY 3D Modelformat. If you don't have a compatible application, the most reliable approach is to convert the file to a more universal format using the converters listed above. Most PLY 3D Model files convert to widely-supported alternatives in seconds.
