Universal 3D File
An open-source compressed file format that was initiated by the 3D Industry Forum. U3D is designed to store three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates. Here are some of the key features and advantages of U3D:
- 3D PDF Integration: U3D enables the generation of PDF documents that contain interactive 3D data. This means that you can view, rotate, zoom, and manipulate 3D models within a PDF document. 3D PDF is a widely used and supported format that can be easily shared and distributed.
- U3D File Converters: Autoconverter and Automesher Application are capable of reading and writing to and from the U3D file format. This allows you to convert your 3D models from various formats, such as STL, OBJ, SKP, DAE, STEP, and others, to U3D and vice versa.
- IFX Conversion Library: Our U3D file converters use the publicly available open-source IFX conversion library provided by Intel. This library is a powerful and reliable tool that enables the conversion of 3D data to and from U3D.
CityJSON File
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 Files 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.
