PLY Polygon File

A file format specifically designed to store three-dimensional triangles along with additional properties such as color, normals, transparency, or texture coordinates. PLY is also known as the Stanford Triangle Format, as it was developed at Stanford University in the early 1990s. PLY has many applications and benefits for 3D graphics, such as:

  • Rich and Customizable Data: PLY is a comprehensive and flexible format for 3D triangles, as it can store not only the geometric information of the triangles, but also the material and appearance information of the vertices and faces. PLY also allows for the definition of custom properties and elements, which can be used to store any additional data that is relevant to the 3D model.
  • PLY File Converter: Autoconverter allows you to convert your 3D models from various file formats, such as STL, SKP, OBJ, DAE, 3DS, STEP, and others, to PLY and vice versa.
  • Binary and ASCII Formats: It’s worth noting that PLY files can be saved in either binary or ASCII text formats. The binary version is generally preferred due to its significant reduction in file size and faster loading speed. However, the ASCII version is more human-readable and easier to edit. Our PLY file converter can handle both formats and convert between them.


A file format for the efficient storage and exchange of 3D city models and landscapes. It has the following benefits and features:

  • Optimized CityGML: The CityJSON format is based on CityGML, which is an OGC standard for representing and exchanging 3D urban data. However, CityJSON is optimized for simplicity and efficiency, using JSON instead of XML as the underlying syntax. CityJSON reduces the file size and complexity of CityGML files, making them easier to process and manipulate.
  • 3D City Data: The CityJSON files can store 3D city models and landscapes, which are composed of various city objects, such as buildings, roads, bridges, vegetation, etc. Each city object has a name, a geometry, and a set of attributes. The format also supports nested hierarchy, reusable geometry component instances, and custom materials with texture images, which enhance the realism and detail of the 3D city data.
  • CityJSON Converter: Autoconverter allows you to import and export CityJSON files, and convert them into various other 3D mesh file formats, such as STL, OBJ, SKP, 3DS`, etc. Our software supports the reading and writing of CityJSON geometries with custom attributes, which preserve the semantic information of the 3D city data.
