This has a lot in common with Progressive Buffers, and works with arbitrary geometry not just voxels: http://www.cs.ust.hk/~psander/docs/progbuffer.pdf http://www.cs.ust.hk/~psander/docs/progbuffer.pdf If vertex clustering is used as the simplification algorithm, there's no need for the geomorphing buffer and seamless LOD morphs can be done entirely in-shader. Video showing LOD-morphing here: https://youtu.be/akOk2wAb0yo https://youtu.be/akOk2wAb0yo A number of commercial game engines use similar techniques. The advantage of using geomorph buffers is that higher quality simplification algorithms can be used for greater quality and efficiency. A pure vertex clustering approach is simpler and allows for smaller data, which may be better for streaming i/o.
