'''Article(s):''' [[Problem of Apollonius]]

'''Request:''' I believe this image would be far better if provided as a Scalable Vector Graphic. Conversion would be simple for one with the appropriate skills. -- [[User:Horst.Burkhardt|Horst.Burkhardt]] ([[User talk:Horst.Burkhardt|talk]]) 12:22, 14 February 2008 (UTC)

'''Addendum:''' ''It may be more profitable to base the SVG on [http://astronomy.swin.edu.au/~pbourke/fractals/apollony/big2d.gif this image] (the original source image) so as to get higher detail.'' -- [[User:Horst.Burkhardt|Horst.Burkhardt]] ([[User talk:Horst.Burkhardt|talk]]) 13:10, 14 February 2008 (UTC)

'''Graphist opinion:'''

:I really do not think this should be represented by an svg. Fractals do not scale well. If you scale them up, you will need to reiterate it to have smaller details. I think this should be in png format. [[User:XcepticZP|XcepticZP]] ([[User talk:XcepticZP|talk]]) 13:53, 14 February 2008 (UTC)

::I beg to differ - not only is this a sequence of fractals, but it is also a bunch of circles in a pattern. Surely that means the SVG would be a very very simple thing to create? As long as you can somehow lock the pattern in place (group all the objects) it would be more than possible to create an SVG. Nonetheless, i'll work on a PNG of it when i have time. [[User:Horst.Burkhardt|Horst.Burkhardt]] ([[User talk:Horst.Burkhardt|talk]]) 13:59, 14 February 2008 (UTC)

:::It's possible (though complicated and time-intensive) to take the original fractal algorithm and code a program to produce the SVG. It would be more accurate that way, but the question is whether or not somebody actually wants to try. Depending on how far down you go, it would probably pass [[WP:FPC]] right away. Seems like a challenging project if somebody wants to try. -- [[User:Ipankonin|I. Pankonin]]&nbsp;([[User talk:Ipankonin|t]]&middot;[[Special:Contributions/Ipankonin|c]]) 05:15, 15 February 2008 (UTC)

::::I'm tempted to try an automated SVG, so I'll give that a go but if it hasn't appeared in a couple of weeks I'll have given up ; ). In the meantime I'll convert the GIF to a PNG, just on general principles. [[User:Time3000|Time3000]] ([[User talk:Time3000|talk]]) 15:47, 15 February 2008 (UTC)

:::::I've done an SVG; it takes a while (in the region of a second) to render on firefox using this machine as there's a lot of detail, but that shouldn't be a problem. [[User:Time3000|Time3000]] ([[User talk:Time3000|talk]]) 13:53, 18 February 2008 (UTC)

::::::If it's not too difficult, I would take the stroke width down to .25 and fill in the empty spots that appear. I wouldn't worry about the size until it gets above a megabyte. Did you really automate it? -- [[User:Ipankonin|I. Pankonin]]&nbsp;([[User talk:Ipankonin|t]]&middot;[[Special:Contributions/Ipankonin|c]]) 10:53, 19 February 2008 (UTC)

:::::::Using .25 for stroke width gives a very washed-out image, so I used .5 instead which does improve it. Yes, I did automate it, which was... a challenge. The idea is so simple, but you have to bring in some fairly advanced geometrical ideas to actually quantify it. I guess I have [http://mathworld.wolfram.com MathWorld] to thank for most of those.

::::::::Some gaps appeared because of the stroke change. -- [[User:Ipankonin|I. Pankonin]]&nbsp;([[User talk:Ipankonin|t]]&middot;[[Special:Contributions/Ipankonin|c]]) 07:05, 22 February 2008 (UTC)
