Title: Organic Mandelbulb heart Post by: subblue on December 11, 2009, 01:00:47 AM I ported my PixelBender version (http://www.fractalforums.com/mandelbulb-renderings/mandelbulbs-rendered-with-adobe-pixelbender/) to a straight GLSL patch for QuartzComposer. The power value animates from 3 to 12 and back. Took about 8 minutes to render 720 frames at 720x576px with 4x supersampling.

Title: Re: Organic Mandelbulb heart Post by: subblue on December 11, 2009, 08:12:06 AM Thanks bugman. The spikes are generated by capping the z.y component when doing the fractal calculation. Setting the value at or near 0 and carefully tweaking the bailout generates some sharp spikes.
You can also get quite a nice fur effect too :) : (http://farm3.static.flickr.com/2750/4172325017_1437ee3468.jpg) (http://www.flickr.com/photos/subblue/4172325017/sizes/l/) Title: Re: Organic Mandelbulb heart Post by: Nahee_Enterprises on February 02, 2010, 11:02:40 AM I ported my PixelBender version to a straight GLSL patch for QuartzComposer.

I am just now getting around to viewing some of the animations I missed, and this one is excellent in many ways. Plus the speed at which you rendered that many frames is getting close to real time viewing, compared to what it takes to generate such images in most other applications.

You can also get quite a nice fur effect too This has the appearance of an object that has been knitted by hand using a wool yarn. A very nice effect!!

And of course, having infinitely nested fractal spikes, this cactus would hurt a LOT. :evil1: |
