I wrote some new macros to get rid of the intersection
of inside and outside (an Uneven_Translate-Macro).
And some macros now copy other vectors instead
of doing stuff like vrotate(Vector,y*360), so float-
inconsistencies should also be taken care of.

But I tried with max_trace_level 256, and I still get
those black edges on the top-inside of the vase. What
did you exactly do?

I think that some of this is natural behavior. I tried displaying just the
Lathe_Outside object with pigment {rgbt 1} interior {ior 1.56} and nothing
else. I still saw some dark spots. The spots can be minimised by specifying
fade_color at .5.

I thought that the spots might be caused by reversed normals or crossed
triangles, but there is none of that in your mesh except for the bottom/top
intersection which you already took care of.

I do know that the default max_trace_level will give a max reached warning.

I closed the mesh by connectiong all of the meshes and then connecting the
outside pinhole with the inside pinhole. This gave a torus type mesh.

I'm sure you also noticed that the defaut aa settings are not sufficient for
the vase.

Okay, so max_trace_level is of no real concern.

What do you mean with aa settings? Do you mean the
blur_samples of 125 should be higher? They'll be higher for the
final version, of course, but what would you propose?

I also took care of the vase intersecting with the background
mesh (by writing a macro which searches the mesh for a lowest
given axis... hehe, another one for the list), the water doesn't
intersect with the vase and has a better surface normal.

Oh, another attached image showing a new change of the vase.
Notice the nice bumps near the bottom? Adding surface-normals
with these useful sine-waves...

The high blur settings may solve the problem. Other than that, you may have
to use +A0.03 or something like that. I just ran a pic at 1280x1024 with
default aa and shrank it to 640x512. The results were quite nice(attached)

The image will be traced even larger than 1600x1200, because
I will need a 600dpi resolution to print the image with a
color-laser-printer.

Also, I cannot combine AA and focal-blur, its one or the
other. But I'll probably use very high blur-samples, because
focal-blur appears much more realistic.

Well, thanks for your help! I think I'm going through the final
steps of working on blur/radiosity/photon details, cause the
image needs to be traced in a few days time...
