ILI to U3D Conversion
What are ILI files?
ILI is the model file of INTERLIS, the Swiss standard for describing and exchanging geographic data. Before data are passed from one office or program to another, the agreement on what exactly the data contain is written in a file of this type: which kinds of objects exist, such as parcels, buildings, and roads, which attributes each has, how they are related, and which rules the values must obey. The data themselves are not stored here but in separate transfer files, so that one model can serve many deliveries. INTERLIS was created in Switzerland in the 1990s for cadastral surveying and is now mandatory for official Swiss geodata, and it is also used in other countries. There are two versions, INTERLIS 1 and INTERLIS 2, and both use the .ili extension for models.
What are U3D files?
U3D (Universal 3D) is a standardized file format used to store and exchange 3D models and scenes. It supports geometry, textures, colors, lighting, and animations, allowing complex 3D content to be represented efficiently. U3D is best known for its use in interactive PDF documents, where users can rotate, zoom, and explore embedded 3D models. The format is widely used in engineering, architecture, manufacturing, medical imaging, and scientific visualization.
