Mesh
The Mesh type stands for simple 3D models that consist of a 3D geometry and attributes. The 3D geometry can have materials such as colors or textures.
An object of type Mesh can have any geometry consisting of polygons, as long as all polygons consist of at least three distinct points and each polygon is coplanar. The object does not necessarily have to be a solid.
PlexMap supports the following formats for Mesh:
File Format | Description |
CityGML | The standard for 3D city models. Contains semantics (buildings, land use, TINRelief, etc.). |
CityJSON | The modern, efficient JSON encoding of CityGML. Ideal for fast imports. |
Collada ( | An open exchange format for interactive 3D applications. It is often used to transport data between software such as SketchUp, Blender, and GIS systems, while preserving textures well. |
DXF ( | (Drawing Exchange Format). Ein von Autodesk entwickeltes Format für den Datenaustausch zwischen CAD-Programmen. Es ist ein Standard für Vektorzeichnungen und einfache 3D-Drahtgittermodelle. |
glTF ( | Provides GPU-optimized, indexed geometries including material properties for high-performance 3D web visualization. |
KMZ ( | A compressed (zipped) version of a KML file (Keyhole Markup Language). It is primarily used for Google Earth and contains textures and icons for 3D visualization in addition to geodata. |
OBJ ( | A widely used format for 3D objects (textures are provided via .mtl). |
3D-Shapefile ( | An extension of the classic ESRI Shapefile. It stores geometries with Z-values (height). It is a standard in the GIS field, but can represent less complex building structures compared to CityGML. |
STL ( | (Standard Tessellation Language). Describes only the surface of 3D objects using triangles. It is the standard for 3D printing, but contains no information about colors or textures. |
X3D ( | The ISO standard successor to VRML. An XML-based format for representing 3D computer graphics, specifically developed for use on the web. |
In addition to importing as Mesh, PlexMap also provides other data types to map more complex semantic information:
CityGML and CityJSON files can also be read in as CityObject to keep the complete CityGML semantics in PlexMap.BIM: IFC files can be read in as IfcObject to keep the IFC semantics in PlexMap.
