I’ve been drooling over some screenshots and trailers from the upcoming strategy game Supreme Commander lately and I’m kind of stumped. What kind of black magic are these guys doing? The landscapes are huge and gorgeous. I figure that the LOD system might be something a kin to clipmapping, but the texturing is a conundrum to me. When the maps are zoomed out it looks like some ordinary texture wrapped on a heightfield, but when zooming in there are a lot of details. Does anyone have a clue about how they have solved this? My apologies if this have been discussed before. // Hubert \

Well, whatever they are doing the system seems to handle detail quite well.

The transitions between textures in this picture are really nice.

And it looks quite good from a distance as well.

I wonder how they structure the textures for each map. Could it be a grid of terrain chunks textured with splatting when zoomed in and perhaps a regular static texture when zoomed out?

No, doens't look like anything special.
The first pic looks like a high-res static decal texture. IE a unique texture that's placed on top of your standard splatted terrain textures.

The 2nd one just looks like standard splatting.

I think those pics are exceptional! It could be just me. Those are just extremely detailed textures though, but its the way all the textures come together in the game that make them look so cool!
Those models are also highly detailed.

Well thats called the magic of shaders...There are many ways to accomplish such things:

Texture splatting, macro textures, cross fading, etc..

Mega textures as described by Carmack would have good quality but in my opinion are too cumbersome because of the huge memory requirements.

As Chris Taylor said in an interview (video footage on one of the last GameStar issues), they use a megatexture.
But I believe they do a reasonably amount of the terrain eye candy with heavy use of shaders.
