Planet and quad tree mesh in Unity?

Folks,

Anyone have idea how to achieve the same on Unity?
Check this video:

He's using what he calls quad tree mesh, which basically adapts the mesh as the camera approaches. Making possible to create a Spore like game.
Would be nice to have a similar example in Unity.
I'm thinking in creating a high detailed planet mesh and see how unity will adapt to it. What you guys say?



Quad tree mesh in wireframe mode shows how the surface adapts to the camera position.

Its just a level-of-detail thing. Whether the mesh is truly stored in a quad-tree, I don't know, but it would kind of make sense for a sphere/planet, then the closer you get the deeper you go into the tree branches.

 

The guys from the Kerbal Space Program had a really good (and crazy) presentation on this. They had some pretty insane and very fast detail swapping all inside Unity. There are some interesting issues you'll run into when trying to get the higher detail meshes lining up with the lower detail meshes that they solved quite nicely, among other things.

 

Isn't there a thing on the asset store already that does this kind of LOD planet thing?

Any ideas where i can find this?

Or was only just done at Unite?

 

The Unite channel just uploaded our presentation.

The section presented by Mike is mostly about how we did the planetary terrain. Hopefully it'll be of some use to others going down that long twisty, floating-point-jittery road.

Cheers

 

Sweet. Looking forward to watching this.
