Lighting simulation

Lighting simulation provides lighting engineers with a tool to determine the optimum lighting solution for a building. Its main innovation is that it provides an interactive interface allowing users to change the configuration of both light fittings and furniture in the rooms in near real-time. Users can walkthrough the building, as changes are made to the scene, and the new lighting solution appears progressively. If a light is modified or an object in a room is moved, the update of the lighting will be produced in an interactive time (less than 10 seconds, usually less than 5 seconds).

Additional features of the simulation are:
Multiresolution lighting: integration of multiresolution module (result 9) to provide a rapid update lighting solutions.

Full collaborative working: Lighting engineers and all participants to this simulation can run the application at the same time on the same model but at distant sites. They are able to work collaboratively on the model, with updates to the model sent to other participants in real-time.

The current release includes all these features but is only working with simple scenes. Future work aims to take into account complex geometries (curved walls for example), and to include textured scenes.
