Looks amazing.

 

I wonder how do they blend the geometry with the terrain so well.

It looks a bit more complicated, I don't know if it is a video compression or not, but when they put an item, the pixels around it change a bit.

Reprojection

i'm not familiar what that thing is?

Otherwise i suspect something similar to that technique "soft particles" applied on the terrain. But it has to be something a bit more complicated.

When I saw that video, my assumption was that the terrain is using some kind of 'mega-texture' / texture composition cache system, including colours and normals at least.

The "terrain" shader is extremely simple - just sampling out of this mega-texture.

The "terrain object" shader (used on rocks/etc) can then sample the terrain heightmap and determine how close to intersecting with the terrain each pixel is. As this approaches zero, this shader can sample the terrain's mega-texture and replace it's own colour/normal with the terrain's colour/normal, creating what looks like a smooth intersection in the shading, even though geometrically it's a sharp intersection.

 

And yeah, it looks amazing. When playing SWBF, I thought that a lot of the terrain was unique meshes, when in fact it's just a combination of a height map and "kit-bash" meshes - with this magic technique hiding the transition from height-map to mesh! :o

Props to Dice!

I believe the engine used for Metal Gear Solid does something like this, or at least mentioned an explination for how this could work. http://www.gdcvault.com/play/1020197/Landscape-Creation-and-Rendering-in

The other thought is that they are not using actual colored textures for some of their objects. And instead are using a series of black and white textures that can be tiled and combined to make new materials. This would make it fairly easy under the right projection to blend things in.

 

Or... well till the DICE guy posted information :P
