Voxels and LOD in Unity

LOD is pretty straightforward to implement in Unity: Simply create a parent game object with a few child objects for the different distances attached as children, and have a script that, depending on the distance to the active camera enables/disables the renderers of those different object versions. You could also add complexity, e.g. depending on the number of objects currently visible or the current frame rate.

With voxels, I don't think this is possible in Unity at all, since AFAIK, voxels are a completely different approach for rendering (which simply isn't implemented in Unity). But maybe I'm missing something here (voxels combined with LOD might be a completely different story).

There's one forum posting regarding voxel based terrains in Unity: Voxel Based Terrain

And one pretty popular entry on Unity Feedback: Terrain: Voxel-based terrains
