I'm glad you like it. This uses a multiresolution mesh, which first streams

in the significant polygons, later streaming in detail polygons. The Intel

implementation uses multires mesh as well as subdivision surfaces, which

actually creates additional curvature detail on the client.


One hidden use of multiresolution mesh is in variable level-of-detail. This

wouldn't matter as much in the MetaStream renderer, where you're usually

manipulating a single object, but is very handy in the Shockwave 3D

renderer, where objects can lose detail as you move further away from then,

increasing overall rendering speeds as you move through a world.
