Illustration of SimPLU3D results


SimPLU3D is a set of Free and Open-Source Java libraries allowing the simulation of 3D built configurations that optimize a numerical utility function under the respect of morphological constraints. These libraries are used to question the relations between morphological constraints (that may appear in local urban regulation) and the produced urban fabric at the scale of a district or a whole city. The SimPLU3D approach is generic, as it is possible to use customized constraints, utility functions or type of geometric shapes.

Principe de fonctionnement de SimPLU3D


When applied on local urban regulation, this library is notably used to answer to the following questions:

  • How many dwellings may be built on a parcel ?
  • How may the urban fabric of a district evolve if the local urban regulation is changed ?
  • Could the future buildings cause too important shadowing on the neighborhood parcels ?

More information

All the necessary libraries are available in the GitHub SimPLU3D organisation and are developed and maintained by the STRUDEL team of the LASTIG lab from IGN.

For more information, visit the SimPLU3D website. A tutorial is in particular available to help you set up your own simulations.

Finally, SimPLU3D is usable with OpenMOLE thanks to a specific OpenMOLE module.
