VRay

Heres a screenshot of VRay running on 10 computers

each computer handles a bucket, and sends it back to the host

the image would have taken 5 hours on 1 computer, instead of the half an hour it rendered in

because of the GI and raytracing

It certainly makes GI affordable on almost all projects now :)

 

If each computer had a dual cpu

it would have 20 buckets rendering :)

 

I remember the days when Radiosity used to take overnight...and more :D

I havnt had too much problem with vray,

it requires all the computers to be setup very similar.

We have excellent tech support here...so it has worked almost perfectly.

As far as i know, the Vray team is working on a version with photon mapping with DR,

although i have to admit...ive used caustics only once in my architecture.

 

heres a piccy with some caustics....only took 3 mins to calc the caustics anyway,

so it certainly isnt a biggie for me if it doesnt get included.

Hi WOLF

 

Excuse me if I ask it but I speak english a little bit

What do you mean with this msg that VRAY distributes the calculation of a SINGLE FRAME on multiple machines?

 

PLEASE ANSWER ME

Hey Stefano

 

what Distributed rendering means,

is that 1 computer breaks up the image into small chunks,

and sends each chunk to a different computer.

when each computer finishes its bit, it sends it back to the host, and then starts on another chunk

 

what that basically means

if 1 image takes 10 hours to render

and you have 10 computers

you can render the same image in 1 hour only

 

so if u have 10 2ghz computers at work

its like having a 20ghz machine for rendering

So you tell me that VRAY support this option like Mental Ray a small part of one frame is calculated by different computers.

Great

I didn't knew this options.

Now is more better of Final Render

Excuse me but you aren't WOLF3D but only WOLF.

If you are Wolf3d I know you.

finalrender stage-1 will support this too.

the problem with vray is that you can only distribute brute-force GI with it right now, which is slooooow.

distributed calculation of GI-photon maps (irridiance map) is not yet possible, which makes it not very useable for me right now, since the photon map calculation takes often longer than the actual rendering.

besides it doesn't work very reliable, because its a 'hack' of the standard max network rendering.

lets see who brings us the first 'perfect' DR-functionality, my bet is fr-stage-1, i'm curious to see how brazil 1.0 will handle it.

Hey Marc

 

im not at liberty to say much, but the beta im currently working on,

will answer a lot of your wishes :)

 

but what i can do, is give you a quote from the vray public forum.....

 

------------------------------------------------

 

Well, in the next build, VRay will be able to compute a separate irradiance map for each bucket. This will allow you to render a region without computing the map for the whole image. It will also allow you to use distributed rendering with irradiance maps more efficiently, since there will be no need for each machine to compute the whole imap. It also saves memory when rendering large images...

 

Best regards,

Vlado

Marc...

 

finalRender stage 1 which is due in October will do it. Vray will probably, from what I know and was told during Siggraph, support distibuted rendering with direct (bute force), irradiance map, and photon mapping within a few weeks. Irradiance mapping will change and will be done a per bucket method which will then work better for distibuted rendering.
