Welcome to Fractal Forums

I just modified my frame generation program to automatically detect the number of processors and spawn one process for each core and took the opportunity to produce a new video, with some of the zoom sequences antialiased.  The video is on my home page at:

http://www.mandelmania.net

There is a previous video on the gallery page.  Please let me know what you think.

Thanks,
Ian

ello, welcome to ff dude :P

i'm dlz the movie now, good speeds, looking forward to it; btw, consider checking out the free x264 codec, it's state of the art (and well-supported in all hd players) and scales very well with cpu cores for compression (i get 140fps encoding with my q6600).

Thanks for the tip.  Is there a web player that will play x264-encoded files?  My video right now on my website is a Flash video...  not bad quality but definitely room for improvement.

Ian

you mean a flash or java based player? euhm, not that i know of, the processing requirements are substantially greater (http://en.wikipedia.org/wiki/Context-adaptive_binary_arithmetic_coding) than previous parts of the mp4 standard, so it's unlikely at this stage.

Ian,

Welcome to ff.

Nice job on the movie. My only complaint is that it's a little long. I didn't make it through the whole thing.

A couple things on your applet:

 -The initial plot looks distorted on the x axis. The main disk does not look circular, and the cardioid looks misshapen somehow.
 -What do the "X Left", "X Right" "Y Top" and "Y Bottom" boxes do? Are they supposed to be input boxes for min and max real and complex values? The boxes are about 1/3 the width of a single character on my screen (A Mac running OS X v 10.5.2 and Safari v 3.1.1.)

Thanks for the feedback!

Hmm, it looks like I have a slight bug in my Java applet in my "symmetrical about" option that slightly distorts the initial display of the Mandelbrot set.  If you zoom in or out, however, the fractal will display correctly.

Yes, the X Left and X Right are the real components, and the Y Top and Y Bottom are the imaginary components of the complex values.  I'm curious about why the text fields show up that way under Mac OS X...  they display fine on XP, Vista, and Linux with the most current JVM (Sun Java 1.6 Updates 5 and 6), and display fine on Safari on Vista.  Unfortunately I don't have a Mac OS X machine (they are so darn expensive compared to PCs) to test my applet on--perhaps in the future I can look into this to fix it somehow.

I believe I've fixed the text field display in the Mandelmania applet as it appears on MacOS X.  If anyone can confirm this, please let me know.  Also, I've made a lot of additional improvements.
