I have spent most of today finishing off my renderer and camera, its now in a working state ready to demonstrate output from a simplification algorithm. I have also managed to find a good source for what initially appear to be suitable models.
On the research side I have been reading about Cell Collapse and Alpha Hulls as well as how Edge Collapse can be extended for use with progressive level of detail.
I am becoming concerned that it is generally unsuitable to use progressive level of detail for the problem that this project is aimed at, as while I can see a place for it with terrain and building geometry, I fear that the depth of objects will be insufficent to successfully utilise the technique.
I may have to attempt to change my specification to either include the world geometry for a more complete solution to the urban environment LOD problem, or remove progressive meshes so that I can focus on the offline generation of discrete meshes and runtime switching.
