Takes 2D GIS datasets and "3dfies" them by lifting each polygon to its height (obtained with LiDAR)
A CityGML viewer for macOS 10.12
A robust semantic-aware utility to convert CityGML data to OBJ, featuring decoupling of objects and conversion of attributes to colours.
Automatic generation of simple interiors for CityGML LOD2
C++ implementation of the shrinking ball algorithm to estimate the 3D Medial Axis from pointclouds.
Because your house is always located at the junction of four AHN2 tiles. MATAHN is a user-friendly way to download parts of the AHN2 datasets, we take care of the hassle of tiles.
