Still didn't get it totally, but i suppose you will post some code
sometime.

I have never gotten acceptable results with the tesselation patch on
isosurfaces.  I also remember that 'trace' does not work correctly on
method 2 isosurfaces and IIRC the tesselation patch uses the same
mechanism.

The nice thing about this method is, that it would not use the actual
object but the isosurface function.  My main idea for usage was to speed
up those endless isosurface - radiosity renders and in that case speed is
not so much a problem.  One could save the mesh once it's generated and
reuse it.
