Bad things (and hard to debug) can happen that affect Ray.

This creates shallow copy of object and its children (geometry and materials are shared, transforms are unique).

Added link to library build instructions

Hope so. There is now just a single scene graph update per frame render (plus some extra one-shot updates if light cameras are auto-added to scene graph).

No time right now to re-create the examples using Ray. Will do for r47...

Also fixed RTT example - seems UV mapping for SphereGeometry is now rotated 180 degrees.

Too much caching can break things.

Dynamic terrain example now creates a specular texture from the color texture. That saves 2.17 MB download.

Just I had to drop materials pre-initialization, for some reason this doesn't play nice with having extra scene / render target :S.

In theory also detail normal texture could be computed from the color texture, just we need some nicer normal map filter (Gimp plugin has 9 different ones).

The picking code seems to be buggy... will investigate.

Now uses Face4 where posible.
Adde phiStart, phiLenght, thetaStart and thetaLength as extra parameters (useful for doing google-earth-like stuff).

This will need a rewrite anyway...

UVs are hard indeed.
