Research code
Private: access restricted to Arches team of the LIRIS laboratory.
Our team works on innovative methods to generate realistic Virtual Worlds. Our research encompasses procedural generation, ecosystem simulation, terrain synthesis, cloudscapes generation, and river simulation.
Arches is a platform for the simulation and procedural generation of complex virtual worlds. It It gathers and combines the developments of the GEOMOD (2008-2020) and ORIGAMI (2020-2024) team at LIRIS on virtual worlds. Arches runs on Windows, Linux and Mac OS, and relies on the Qt6 library for the creation of the user interface. The platform includes multiple tools for modeling and rendering large landscapes with many details. The results can be used directly in professional software such as Autodesk Maya or Vue from E-on software.
