Title: Buddhabrot animation using OpenCL Post by: amarzo on June 08, 2011, 01:01:40 PM It was rendered using OpenCL on two Teslas. I know, I know... what a waste of hardware but I wanted to test them.
The problem is not very well suited for OpenCL but even without Metropoli-hasting the GPUs outperformed the CPU. Here it is a link to more highres screenshots and to the source code (Java + LWJGL). http://www.infinityk.com/buddhabrot-rendered-using-opencl/ The first half of the video is kind of boring, only playing with the transfer functions. In the middle part I render only orbits which certain scape iterations, and in the last part a render of the low scape iterations orbit is shown (but changing the exponent value). http://www.youtube.com/watch?v=jnh53UYZGe8 Title: Re: Buddhabrot animation using OpenCL Post by: ker2x on August 07, 2011, 11:18:09 PM awesome :love:

Even my ati 4350 outperforms my cpu (athlon 64 x2) when it comes to opencl performance (with around a factor 3 in fractal renders), no wonder you can do the same trick with 2 tesla's. I'm currently on a opencl renderer as well, 2d fractals already work, hope to get the first mandelboxes out next week. |
