AAt this stage this mostly represents the d.c. characteristics as seen in a diode datasheet or from a spice simulator , A complex Newton iteration might also be efficient in this instance . Presently I'm looking at modeling the response for an arbitrary input signal , to do so discrete convolution is required ; this most likely can be implemented , within fractint , via the Z-Transform . There's at least one region where a minibrot seems to appear , as mentioned in the comments . The diode characteristics vary for varying temperature , I successfully modelled this , however I didn't bother including this in this particular fracint formula . ----- Original Message ----- From: JackOfTradeZ@comcast.net To: fractint@mailman.xmission.com Sent: Friday, July 17, 2009 1:34 PM Subject: Re: [Fractint] Diode Animation? . Well, I finally got it to work with tweax; it is one of the most interesting images I have seen, like with all the dots. However, there are no parameters to tweak so I can't do a morph animation, or as I was hoping, something that would model electricity thru a diode or something. Zooming in gets you nowhere fast; zooming out is ok for a few orders, then it STOPS at about E-005. You cant back out further - keep getting the same image. (I have seen this before. Strange) . ------------------------------------------------------------------------------ _______________________________________________ Fractint mailing list Fractint@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
