Work in Progress/Tests / testing fixed blend

« on: 2014-07-28, 11:08:24 »

Hi. New Blend works very well. But reflections are cleaned from noise very quickly and highlights are still very noisy in complex Blend material((
simple scene (plane, teapot and 8 light)
1 picture - blend in blend  (create GGX BRDF) - 400 passes - very noisy highlight.
2 picture - a simple blend - less noise
3 picture - a simple mat - almost no noise
4 picture - blend in blend 1k passes - still noisy

render settings - default, image filter - off

[Max] General Discussion / Test performance xeon 56xx series (Benchmark)

« on: 2013-12-03, 14:45:22 »

Couple xeons 56xx OC series in cinebench give more than 20 pts
In corona benchmark they speed comparable to 3930K @ 4,7 GHz (which gives in cinebench 14 pts)
Why?
Test this simple scene in A5 (100 passes)
or
build from 17.09 (100 passes)

[Max] General Discussion / Real intensity of light and more...

« on: 2013-09-04, 15:40:36 »

Hi.
When Ondra added support for photometric lights I decided to compare lumens with CoronaLightPoint


it turns out that one coronaLightPoint is 3.72 lumen

maru: that does not make sense yet, because there is no physical camera

Yes, but I decided to find out.
if the exposure compensation (EX) = 0 which parameters can be in a real camera?
having as a reference photometric lumens
downloading maxwell
I set the intensity to 476 lumens (128 CoronaLighPoint)


EX increase on 1 increases the shutter speed by half

so if you take the f/stop(5.6) and ISO(100) as a constant, then EX = 0 gives a shutter speed 1/4s

the same with the ISO if the increase is three times the shutter speed and reduce the ISO three times will be the same result

These are my thoughts and decided to share. :)
