Terrain with LOD

[blaxxun]

Hello Forum,

Is there a way to have a Terrain with LOD?

For example i have a bunch of heightmaps from WorldMachine in tiles which are matching on the edges.
From this tiles several pointclouds get generated.

The resolution of each pointcloud gets more and more dense when coming closer to the camera.
Until the point where every pixel on the heightmap represents a particle.

Then each pointcloud gets meshed.
Each Mesh Tile gets a planar XZ Texture Projection.

This way it could be possible to create almost "infinite" Terrain.

On top of this created Terrain there could be particle scattered (also with View Distance reduction) which can
be replaced with grass, trees, rocks and so on.

Does such a thing maybe exist already?

Make search about Softimage ICE and LOD, there are some stuff out there.
