During their first week-long workshop, the Durian team have gone over the requirements for new/improved Blender functionality. Brecht did a write-up on the Durian blog.
Today we discussed Blender features, trying to get an overview of the things the artists really need to complete the project. This is only a rough overview, we didn't discuss all topics yet, a more complete and detailed list will be compiled later, for developers interested in getting involved.
You'll find lots of interesting things on the list such as improved sculpting performance, the B-Mesh, improved physics and rendering of scenes with much more detail (which is emphasised by Brecht so I guess 'much more' means insane amounts of detail).
