Procedural City Generation Demo

In This Article:

Procedural City Generation demo showcases the Landscape Tool capabilities for procedural generation of buildings on a landscape. A fragment of the landscape with a city and vegetation was generated procedurally on the basis of GIS data provided by OpenStreetMap with no extra manual editing.

Features#

  • 10x10 km area near the Adler city (OSM imagery data)
  • Buildings generated on the basis of OSM vector data containing the number of floors
  • Automatic texturing of buildings using 3 template materials
  • Vegetation generated on the basis of OSM landcover data
  • Global Water and a single Cloud Layer
