![Anisotropic voxel clipmaps [WIP]](https://i.ytimg.com/vi/kDJA2Yif4fs/mqdefault.jpg "Anisotropic voxel clipmaps [WIP]
Working on big updates to Wicked Engines voxel GI, now it supports anisotropic voxels and clipmaps.
Anisotropic voxels means each voxel has a directionality, so voxel resolution doubles 6 times, once for each face of a cube. Sampling the anisotropic structure requires 3 texture lookups instead of one.
The clipmap is a voxel cascade structure, each level covers a twice as big area compared to the previous level, while using the same resolution. Only one clipmap is updated per frame, so the result lags a bit.
The performance is currently very slow, this will need to be solved before competing the update.")
