TOPOJSON to U3D Conversion
What are TOPOJSON files?
TOPOJSON is a compact text format for maps whose areas touch each other, such as countries, states, or districts. It extends GeoJSON with one important idea: instead of writing the outline of every area separately, it writes every shared border only once, and each area then lists the pieces of border it is made of. This removes the duplicate lines between neighbors, so a TopoJSON file is often many times smaller than the same map in GeoJSON, and it also keeps the information about which areas share a border. Because of its small size, the format is popular for maps on web pages, where files have to be downloaded quickly. The files have the .topojson extension, although .json is also used.
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.
