hi, i registered an icon for me in the www.gravatar.com website, though it
hasn't been rated yet.  Very simple but cool IMO.

However, using povwin 3.6, i could not manage to get it to properly render
in the desired 80x80 resolution: the image could not be centered, yes, even
with up and right adjustment.  No big deal,  just rendered in 180x180 and
the website resizes it.  Still, i found it a bit odd...


well, here it is:

// my gravatar

camera { location -4*z look_at .2*y up y right x }

light_source { -5*z 3 }

union {
        sphere { 0, 2 pigment { rgb .4*z } scale <1.1,.7,1.1> rotate
<-7,0,17> scale z*1.4 translate 1.1*y }
        sphere { x, .7 pigment { rgb <1,.7,.5> }}
        sphere { -x, .7 pigment { rgb <1,.7,.5> }}

        rotate <0,-10,10>
}

The size of the output shouldn't make a difference.
If what you are seeing in the 80x80 output is like the attached image, it
actually is centered, it's just a limitation on the minimum render window
width. The black on the right isn't part of the rendered image, it's just
matting for the render window, the output file should be fine(80x80).

thanks, that's it indeed.  The minimum window isn't resizeable, so i
couldn't figure it out.  I'm not in my trusty Linux either... :P
