I'm trying to make a simple set of web page logos but I want them
to be raytraced and look nice. I can manage to get a single character
to look great, all marbelized and whatnot, but I cannot manage to get
an entire line of them to look non-skewed or have a distorted view.
Ie - I can get about 1-2 characters to look good, but no more.
I found a nice page online with exactly the sort of results I wanted,
but it is all UNIX, so well, me with Windows and just wanting to make
10 or so words appear nicely...
Does anyone have a sample script that they can post? I'm unfortunately
not terribly interested in a huge two week programming exercise - just
something simple.
Oh - one more thing - is there a list somewhere of actual types of
tectures and such? I'm currently guessing on colors and paterns,
which is time-consuming.

Hi,
I tried to create a bottle with sor and wondered about a strange black area.
It's just at the height of the horizon (wether there is a plane or not).
Is it a bug or a mistake of mine?
complete sourcecode:
#include "colors.inc"
camera {
location <0, 8, -30>
look_at <0, 10, 0>
}
light_source { <50, 50, -10> color rgb 1 }
plane {
y,0
pigment {Blue}
}
sor{
11,
<0.006000,0.603000>,
<0.002000,0.574000>,
<0.028000,0.578000>,
<0.031000,0.595000>,
<0.021000,0.602000>,
<0.018000,0.622000>,
<0.021000,0.647000>,
<0.044000,0.700000>,
<0.044000,0.863000>,
<0.000001,0.873000>,
<0.000001,0.874000>
pigment {color Blue}
scale 40
rotate <180,0,0>
translate <0,34.5,0>
}

That's not exactly a bug, if it's what I think it is without looking. Try
adding the sturm keyword to the sor. And if that doesn't work well enough
try a render with the camera positioned offset above the maximum height of
the bottle. If, when rendering with the camera at various positions
alongside the bottle, a dashed line appears even with the camera then it is
the problem I'm thinking of.
I haven't a good explanation, only that it's something to do with the sor
surface creation formula and rays being traced, which you have guessed by
now. sturm is short for Sturmian root solver and it can help by forcing more
accurate calculation. It hasn't always been perfect though, just so you
know. You might be able to insert more (or less) points to enhance the
surface creation and that can also work for some circumstances.
