Embree raycaster for V-Ray

[Delineate]

Did a test too..
Using bhv4

Embree ON - 4m45s
Embree OFF - 6m15s

Image looks identical.

im interested, what happens if you put the embree image over the standard image in photoshop and set the blending mode to "difference" .. its really identical? if not, where are the differences ? im guessing just in the grain pattern.

im planning to test this myself but im in deadline mode so will have to wait.

ahh..not using AVX yet? i assumed the whole thing with embree was that it used every trick the intel chips had inside them to get the fastest result. maybe 2 pints for the coder when he gets it running at full steam.

We'll get to that next week, I hope.

how exciting.. as if vray wasnt really fast already btw, does this benefit RT too?

[vlado]

btw, does this benefit RT too?

For the moment - no. Only the production V-Ray renderer is affected, regardless of what actual GI algorithm is used.

Well, I couldn't wait until next week So I added versions compiled with AVX instructions to the download. I'm not sure if this has any effect on the performance though.

hehe im not sure who is the biggest nerd.. me for being here to download it on a saturday night, or you for uploading it

[super gnu]

dammit i got quite ahead of myself.. i dont actually have an avx compatible cpu. so somebody else will have to test it... from what little i have read regarding avx, it should make quite a big difference no?

I don't know, it didn't seem to make much of a difference on the particular machine I was testing, but I will test a few others as well.

hi Lele, nice to see you again...

I wonder, can phoenix be avx enabled ?

Heh. First crash Domelight. Latest nightly.

Compiling render instances geometry.

Would xeon E5530 benedif from any of these new awesome tweaks?

On a side note how long did it took to developt this tweak ?

[super gnu]

the 5530 is i believe pre-sandy bridge, so it wouldnt support the AVX instruction set.. but the embree raycaster should work just fine... avx should make it go faster, but nobody has confirmed it yet..

I just tried the embree helper on an exisiting scene and it crashes every time.
I am going to try it on another couple of scenes to see if I can get it going.
