A level of detail method for blocky voxels

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

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.

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.

kinda hard to evaluate it without a flyover
