Dynamic Level-of-Detail on the GPU

Junfeng Ji has published a paper on implementing dynamic level-of-detail (LOD) on the GPU. According to the abstract, "a quadtree structure is created based on seamless geometry image atlas, which is a 3D surface representation in parameter space by combining the features of geometry images and poly-cube maps. All the nodes in the quadtree are packed into the atlas textures. There are two rendering passes in our approach...Our LOD algorithm can generate adaptive meshes dynamically, and can be fully implemented on GPU. It improves the efficiency of LOD selection, and alleviates the computing load on CPU."
