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 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.
Point Cloud File
A file extension that is used for ASCII text files that contain point cloud data. Point cloud data is a collection of 3D points that represent the shape of an object or a scene. Each row in an XYZ file consists of 3D point coordinates, typically separated by a special character like a TAB. Here are some of the key features and benefits of XYZ:
- Optional Normal Vectors: Optionally, the XYZ file may also include 3D normal vector coordinates for each point. Normal vectors are perpendicular to the surface of the object at each point, and they can be used to enhance the appearance and realism of the point cloud. Normal vectors also help with the reconstruction of surfaces from point cloud data.
- Mesh Reconstruction: Autoconverter software can be used to automatically reconstruct meshes from point cloud data. Meshes are composed of polygons, such as triangles or quadrilaterals, that approximate the shape of the object.
- Smooth NURBS Surfaces: Autoshaper software allows for the reconstruction of smooth NURBS surfaces from scattered points stored in the XYZ file. NURBS stands for Non-Uniform Rational B-Splines, and it is a mathematical method of representing curves and surfaces. NURBS surfaces provide a more accurate and smooth representation of the object than a mesh.
- Alternative File Extensions: Point cloud data may also use alternative file extensions such as ASC or TXT. These file extensions are essentially the same as XYZ, except for the different characters used to separate the point coordinates. Our XYZ file converters can handle these file extensions as well.
