Thanks Axone Man, that's a terrific mini tut. Interesting to know about the hard-coded settings and over-riding them. There goes any chance of a decent sleep for the next month. I know about the long times, I'm doing a julia at max iterations (which seems to be 2,147,483,647) at the moment and it's going to take roughly 3.5 hours. And I'm pretty sure it won't get rid of the rough bits. Then again, the rough bits sometimes adds to the picture. Had also noticed that the light mode has very little difference between low and high quality render, unless of course you have done a deep zoom, then the higher setting will make a noticeable difference. thanks again grumps =====================================================The Chaoscope mailing-list Archives : //www.freelists.org/archives/chaoscope Admin contact : chaoscope@xxxxxxxxxxxxxx Web site : http://www.chaoscope.org =====================================================
