Luxology modo is a 3D modeling system (in a way similar to 3ds Max). It uses a new interesting modeling approach called polygon/surface subdivision. SubD allows the user to create non rectangular patches and to control the surface curvature in a very natural and precise way.
For the end-users, the quality of results and the speed are very interesting. IMHO, it is important to know that the key people behind modo are all coming from the NewTek LightWave team. Therefore the expectations for modo are very high!
If you are interested, I just completed an interview for the Novedge blog with Brad Peebler, CEO of Luxology. Here is the link:
