Hi everybody,

    It's been a while since I last posted anything hasn't it? Well, first of
all, I simply haven't had anything worth showing, and second, I've been
super busy. I'm taking a 5 credit class that was advertised (and paid for
as) a 3 credit class. Naturally, the work-load is heavier than I planned
for, and that doesn't leave me much time for playing on the computer.
Believe it or not, I've found myself turning it off after finishing my work,
and getting away from it! :O

    But I digress. This weekend I finally had a chance to do some POVing.
(Oh, how I missed it!) I modelled this pot in Rhino, exported a POV mesh,
and converted it to a mesh2 using Warp's excellent mesh compressor. Then I
applied a texture I had been experimenting with previously, and let 'er
render. This was done in 2 passes, the first taking ~6 minutes (at 512x320),
and the second taking ~35 minutes (at 1600x1000). I also did a little bit of
post-processing in Photoshop to clean up some ugly little artifacts.

    Comments and criticisms are welcome. I hope you like it. :)

I like it! And it's beyond me how you made a beautifully 'melted' surface
with the Rhino interface.. At least to me, Rhino doesn't allow wonders, but
usually complains about what I'm trying to do, even though I follow the
simple toturials! The menus are full of options that fails to work.

Great!

I never said it was easy! It took a lot of messing around to get this. It's
not exactly what I had originally planned either, but I'm happy with it. :)

Yeah, it is a bit difficult sometimes.

very nice pot!, suppose this means I will have to dig rhino out and do
something now :)

Hmm... mysterious. A clean dish, empty except for a ball. A dog thanking 
it's owner for a good meal, perhaps?

Nice modeling of the dish. I'm currently frustrated at 3D modelers. You 
see people modeling amazing things like heads and whole characters! When 
I try to do the same, things don't turn out quite right.... Maybe it's 
the tools I'm using (Amapi, HamaPatch, Rhino....).

Realistic lighting you used, too. Nice little touch the radiosity 
produced with the slight caustics near the bottom corners of the dish.

Um, if you like. I meant nothing by it. :)

Thank you!

> I'm currently frustrated at 3D modelers.

I think that unless you move into big name modelers you don't get the power
you need. And even then there is a lot of stuff that you wish you could do,
but that the modeler you're using can't manage (or at least not in a
straightforward manner). This is why studios have to jump around between
several packages to get the job done. :P

> Realistic lighting you used, too.

I used a simple planar on a sphere, and two lights, nothing fancy... I think
it's the texture more than the lighting that brings out that realistic
touch.

That's where the artifacts I removed were. I used 'smart-blur' to make them
into what you see. Before, they were just ugly bands of light and dark.

I know what you mean, I tried those programs too and none of them worked as
I desired.. But I found something nice! I strongly encourage you to try out
"Wings3d" that is an efficient and easy polygon modeller. I guarantee you'll
be able to use it very quickly.

It still needs skill to model beautiful things (fortunately) and the
principles of polygon modelling is not the answer to everything, but it has
some forces. It's not a replacement for modelling with POV but a nice
additional tool.

The program is freeware and under development. At the moment it's not a
texturing or animation tool, but supports common file formats, and has
direct output to POV mesh2 (via a plugin).. However, the plugin currently
doesn't work with the newest version of Wings3d, so I use an older version:
0.94.1.. You may have a look at: www.wings3d.com and let me know if you have
questions.  :o)

Regards,
Hugo

That texture really is neat and realistic. How is it made?

Two passes to first create radiosity data and then render with final
resolution, or for what?

Why thank you! :) But do note that the "environment" is an important
component of the texture.

> How is it made?

Something like this... (if I haven't changed it since this post...)

#declare LayerA =
texture
{
 pigment
 {
  planar turbulence 0.2
  scale max_extent(Pot).y
  color_map
  {
   [0.0 rgb <0.50,1,0.50>/12]
   [0.7 rgb <0.30,1,0.50>/6]
   [1.0 rgb <0.25,1,0.75>/24]
  }
 }
 finish
 {
  reflection {0.1 metallic
  metallic
 }
 normal
 {
  bozo warp {turbulence 0.5}
  scale 3 bump_size 1
 }
}

#declare LayerB =
texture
{
 pigment {rgbf 1}
 finish
 {
  reflection {0,1 fresnel}
  specular 0.125 roughness 0.01
 }
}

#declare PotTex =
texture {LayerA}
texture {LayerB}

#declare PotMat =
material
{
 texture {PotTex}
 interior {ior 1.4}
}

> Two passes to first create radiosity data and then render with final

One pass for radiosity data without reflections at a low resolution, and the
final at a high resolution with reflections.
