Title: Some "renderings" Post by: mrrgu on December 20, 2009, 04:58:46 PM Hello
Ive made some renderings using David Makins formula for the mandelbulb. Calling them renderings I have now realized is to go to far.. Since they are made of big blocks of 3D data that I rotate around.. sorry I did not know better :) The interesting part though is that by setting scaling of r,theta and phi individually like this r^Na, Nb*theta, Nc*phi and using different Na,Nb,Nc.. you can get new things! Negative numbers and fractions work for all three of them. Na=2.0,Nb=1.0,Nc=2.0 gives something looking like the original mandelbrot(without distorsion).. I don't claim this to be "the 3D mandelbrot"..since there is no fractal behavior in the newly added dimension..just boring and smooth. See here for some attempts: http://www.youtube.com/my_playlists?pi=0&ps=20&sa=0&dm=0&p=F1D2C1C7D4E1C70D (http://www.youtube.com/my_playlists?pi=0&ps=20&sa=0&dm=0&p=F1D2C1C7D4E1C70D) Also tried Na=Nb=Nc=-8 ..yes negative! it will make a new kind of mandelbulb as well..so far I have not gotten colors good on that one..they keep hitting max iterations..making it all white.

Calling them renderings I have now realized is to go to far.. Nice to see someone else playing with voxels. I think the term rendering is justified, maybe not "artistic rendering" because of its technical look. |
