Hey Robert! That is looking very good!

Seems we have been doing pretty much the same thing these last days. I have 
revisited an old scene of mine (Alien Cliff) of a couple of years ago, which 
consisted principally of two isosurfaces: a cliff with scree slope, and a 
hardground. I used those two isosurfaces as input for the MeshShape() macro, 
used a pretty high resolution (500) and got these things, after I processed 
them once through Poseray in order to smooth out some too visible faces.

I am quite satisfied with the cliff and scree mesh. I am much less satisfied 
with the hardground which show a number of artificial outcrops which I have 
to remove one way or another. More testing is needed here.

However, overall, the isosurface shape is faithfully transformed into a 
mesh, thus dramatically reducing render time.
