Photorealism - Utopia II


Another study of my Utopia morph. I love the way her skin turned out in this picture!

Is there any way to donate CPU cyles? It's painful reading about how long it takes to render.

*LOL*... Thanks! That would have been nice. I did a benchmark test render the other day, and it turned out that it took me 26 minutes to render something that most of today's computers will render in 3-5 minutes. I'm on a 2.4 GHz P4 engine with 800 MHz FSB and 1 gig of DDR SDRAM. You need dual- or quad core processors with 4 gigs of ram for this job, really.

Between the assorted computers I have, I make about 26 mkeys/s on distributed.net RC5. (about 9 cumulative gigahertz)

I know that you can specify which lines to render in povray, and thus split up a render between many computers that way. Is there any way to do something like that with your render engine of choice?

Well, Carrara 6 Pro has multi-core support. It also uses memory better on 64-bit systems. If I had a multi-core processor, most of the rendering processes would be distributed among them. Precalculating the lighting is still single-processor, but the actual rendering can be split as many ways as needed. Each processor gets it's own little section of the image to render, and as soon as it is done, it gets a new section. But the key is all in having enough memory for each processor, so that nothing needs to be cached to disc.

And yes, Carrara 6 Pro is capable of network render. Don't know how it works, though. With multiple processor cores in a single computer, it's just to tick a box and off you go, but network rendering takes some setting up...
