[Bf-funboard] Adaptive displacement mapping.

[Luke Wenke]

Good idea. I think that there should be adaptive subdivision no matter what
the quality setting is. The quality setting could just affect the overall
amount of subdivision.

Hi,
I find it very the whole displacement mapping thing kind of akward. Instead
of subdividing a mesh into billions of faces, I think could better be
organized this way:
1) Apply the displacement map directly over you low poly mesh.
2) Then a routine will adaptively subdivide the mesh according to a
"quality" parameter along the value gradients of the displacement map.
3) Finally displace the map.

In other words,  subdivide more heavily in areas where there are lots of
heights differences, and do almost no subdivision where the height changes
are non existing or almost negilable. This should leave you with a more
managable poly count.
