Quad G5 and Renderworks

[Peter van der Elst]

Does Renderworks use all 4 G5 processors?

ie. Is rendering twice as fast then?

Thanks, Regards

Hello Peter:

Although we don't have one to test, it should use all four cores. We have dual Xeon hyperthreaded machines here that render with four threads.

Note that raytracing is the only operation that is multithreaded in RW. You would only see measurable gains with scenes that have a lot of reflections, etc.

So radiosity isn't supported in dual processing? Isn't that a processor intesive procedure?

[Dave Donley]

Hello grant_PD:

Radiosity render modes use a single thread/processor to generate the radiosity solution. They are not multi-threaded.

I guess my question is: Which is more processor intensive radiosity or raytracing? I spent a lot of money getting dual processor machine to improve Renderworks' raytracing. Is radiosity comparable to the amount of processor power needed by raytracing?
