Lame glass animal? I've seen real glass elephant ornaments that look
almost exactly like this one...

Your observations are valid because they are based on what you saw :)

Actually the tusks were very ivory-looking in the pre-test renders but
I was using a single shadowless light source. Now the light is orange
(in average). Hmm... I might change that. You're right though, the
tusks don't look like ivory at all. The eyes are in fact blue but of
course this can't be seen with this type of illumination.

Nope :) There's a story behind all this but I'll post it with the
final render.

Sheevah is even more challenging to model :)

I'll try to model a Pegasus when I am through with this project. Now
*that* is challenging (detail level will be an issue for that
project).

Thank you again for your feedback.

Same here, I think the there is a lot more detail to the model than's shown
from this render (the refraction of the glass masks the real detail).

I like it, and it's cute :)

I like!

With regard to the floor/table confusion, you might be able to avoid this if
the table corner wasn't so close to where a floor corner would be in
relation to the wall corner. At the moment the eye is tricked into seeing
the table and wall as contigenous.

With regard to the model, the transition between the legs and the body looks
a little abrupt, but this might be a feature of the real model.

Please post the china (or whatever) version.

	Try something like that:
#declare Normal = function { pigment { granite } }
#declare Depth = 1 ;
isosurface {
  function { (Normal-0.5)*Depth-x }
  bounded_by { box { -<Depth, 1, 100>, <Depth, 10, 100> } }
}

	For a piece of wall with the outside normal in the x
direction

  What really fascinates me is the internal glow of the glass.  I
actually do glassblowing and hot glass sculpting, and the colors are
*exactly* as if the object was currently being worked.  Very, very nice.

And note that in the most recent MegaPOV the "contained_by" keyword 
replaces the original function of "bounded_by", so "bounded_by" now 
should behave the same as in other objects. The "open" keyword is used 
to get the same effect as you get with "clipped_by".

Hey, thanks, I wasn't aiming for this effect but it contributes to the
idea I have about the image.

He's cute!   I like the walls, but the table looks rather simple next to
them.

Sometimes its hard to put life in a pov image; you've done a terrific job of
accomplishing just that (even if it is a model of an inanimate object).

Here's a 30x30x30 (I think) rounded box, made out of clay with a nice color
map, the camera is currently inside the box looking towards a corner.  If
you need help changing the way it looks don't hesitate to ask:
-------------------------------------

#version unofficial MegaPov 0.4;

isosurface {
  function { x^20+y^20+z^20-1-noise3d(x*15,y*15,z*15)/10
    -noise3d(x*60,y*60,z*60)/20 }
  contained_by { box { -1.1,1.1 } }
  threshold 0
  accuracy .01
  sign -1

  pigment { bozo color_map { [0 rgb <.9,.8,.7>]
    [0.5 rgb <1, .9, .8>] } scale <.1,.5,.1> }
  scale 15

}

camera {
  location <0,0,0>
  look_at <-3,-3,7>
}

light_source {
  0
  color rgb 1
  translate <0,0,0>
}
