3dfier

Takes 2D GIS datasets and "3dfies" them by lifting each polygon to its height (obtained with LiDAR)

azul

A CityGML viewer for macOS 10.12

CityGML2OBJs

A robust semantic-aware utility to convert CityGML data to OBJ, featuring decoupling of objects and conversion of attributes to colours.

lod2plus

Automatic generation of simple interiors for CityGML LOD2

masbcpp

C++ implementation of the shrinking ball algorithm to estimate the 3D Medial Axis from pointclouds.

MATAHN

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.

pprepair

prepair

Automatic repair of GIS polygons according to the OGC Simple Features and ISO 19107 rules.

Random3Dcity

A procedural modelling engine natively supporting CityGML, and capable of generating 392 representations of a single building.

Solar3Dcity

A simple utility to estimate the yearly solar irradiation of buildings in CityGML

val3dity

Geometric validation of 3D primitives according to ISO 19107.
