Nicolas, Looks very good so far. Seems very stable even when upping the priority for a little extra performance. I do see one minor GUI glitch... in the view dialog, the Scale, Gamma, and Brightness sliders are cutting off the end of their respective editboxes. One Suggestion: The default iteration value appears to be for an unmagnified image. Once you zoom in, the iterative value should increase to achieve a proportional gain in detail. I know this increases the render time, but how about "allowing" the Iterations to be proportional to the magnification ? I ran a test at 20 million, 40 mil, and 160 mil and the 160 definitely showed an increase in deep detail. Just a thought. BTW, (as James can attest from the Apophysis list, I'm always good for suggesting things! 8^) Have a good one, Jim ====================================================== The Chaoscope mailing-list Archives : //www.freelists.org/archives/chaoscope Admin contact : chaoscope@xxxxxxxxxxxxxx Web site : http://www.chaoscope.org ======================================================
