Hi all,

I've been playing with POV and I've made a simple sig, here it is:

-------------
camera{orthographic location 4-8*z direction 3 look_at 0}light_source{4-8*x,
2}light_source{20+30*x,1}union{box{-.1,z+.1}box{-.1,x+.1}box{z-y-.1,z+.1}box
{x-.1,x+y+.1 clipped_by{plane{1-2*x,-.3}}}pigment{rgb<.8,.2,1>}}
-------------

It's off-center and the camera statement is too long, but careful 
positioning of the camera and light sources is needed... Well, what do you 
think about it? Any ideas to shorten it and "hide" it? :)

  "angle 15" seems to work equally well.

how about this

camera{orthographic location 4-8*z look_at
0}light_source{4-8*x,2}light_source
{20+30*x,1}union{box{-x-z-.4,-x+3*z+.4}box{-x-z-.4,3*x-z+.4}box{-x+3*z-4*y-.
4,
-x+3*z+.4}box{3*x-z-.4,3*x-z+4*y+.4
clipped_by{plane{-x-z+4-8*x,-1.2}}}pigment{rgb<.8,.2,1>}}

it didn't actually shorten it, but it's centered

Shorten:

camera{orthographic location 4angle 15look_at 0}union{light_source{9*<5,4
2>1}box{x-1.1.1-z}box{-z-.1.1}box{-.1x+.1}light_source{4*y
1}box{x-.1x+y+.1clipped_by{plane{2*y-1,-.3}}}pigment{rgb<.8.2,1>}}

Obfuscate (slightly):

camera#macro A(B,C)box{B-.1B+C+.1#end{orthographic location 4angle 15look_at
0}light_source{4*y,1}light_source{9*<5,4,2>1}union{A(x-1y)}A(-z,z)}A(0x)}A(x
y)clipped_by{plane{2*y-1,-.3}}}pigment{rgb<.8.2,1>}}

Actually that was no lossless compression.

Thanks, Warp and Kruger

I've moved the camera and look_at to center the view, and the lights to make 
them shorter (but the effect is not spoiled, at least in my display), and 
changed the order. Now it's centered, shorter, has linebreaks where spaces 
are needed and fits very nicely in 74 colums ;)

71, this time lossless in the picture, though not in the scene:

Great! Thank you very much, I've been fidling with the macro version too, I 
had tried that but didn't manage to get it shorter... Well, I hope you 
don't mind if I take your code and alter the order in a couple of places, 
hehe. :)

As long as you show me the result ;-)

While my version is not short enough to be a sig, I had fun making it as:

#macro S(I,G)#macro a(_ J E L B Y)_,y-J,z-E,L-x,B-y,Y#end,max(x-a(max(I.x
,G.x)max(I.y,G.y)max(I.z,G.z)min(I.x,G.x)min(I.y,G.y)min(I.z,G.z))-z)#end
light_source{y 1}light_source{9+7*x 1}isosurface{function{min(max(y*5+z*4
-x*4S(x-.1.1-z+1))S(-.1+t.1+x)S(z-y-.1.1+z)S(z-.1.1+t))}contained_by{box{
-2 2}}pigment{rgb<.8.2>+z}}camera{orthographic location-z*4+9/4look_at(1-
y)/4angle 30}

It was the sig in the previous post, anyway, here it is the new one, with 71 
columns again, but with a better lighting.
