well i guess it depends on size of model ![:slight_smile: :slight_smile:](https://d1ap1mz92jnks1.cloudfront.net/images/emoji/twitter/slight_smile.png?v=12)
if you want to process lots of photos… gpu helps.
if you want to create a model of a large area, you need lots of cpu. though this would really be better done in network.
then getting RC to use everything it has is another thing.
I’ve found with 2 x 1080 on the job with a little over 6000 photos, at the start would bounce around up 99%. then from half way through it wouldn’t get over 30% for each gpu for the rest. that took about 1.5 days to create the depth maps.
so I would probably go one fast gpu first, and less but more powerful gpu’s. and remember you can only use up to 3 gpu’s per license.
cpu for me takes a lot longer than gpu parts. i’m running 8/16 cores at 4ghz. and these 6000 photos will probably take another 5 or 6 days to run using just cpu.
so keeping in mind the 32 core limit. the best xeon you could go for without wasting money would be a 2667 v4, which is basically the same as i have in the i7 but at 3.2
otherwise i guess you could go a single xeon with more cores, or disable hyper threading.
but really for the time it takes, it would really be better just to have 20 or more pc’s running. but that’s not really feasible at least for me due to license costs.
for me though the biggest thing is max out the ram. 128gb i’m finding is nowhere near enough. i’ve seen pagefile usage over 1tb, but i think a lot of my stuff would fit in 512gb.
saying this, i may have found a solution to my constant crashes due to lack of ram. but I’ll have to wait a while longer to find out.
for storage, i have 2 raid array’s, one is a 2 x 950 nvm. the other is 4 x sandisk.
the 950’s are faster. but they are a bit more all over the place in speeds. you need the setup right, which includes formatting them with less than their full amount. and then don’t fill them up. i just use these for pagefile, thats it. (i also had 1 working at 1x at first and that dropped the speed a lot)
the 4 x sandisk, i think are a better deal. they just work. and i think space and low response times are more important than top speed. though i would be interested in seeing how intel 750 go, i have a feeling they may be better than the 950’s.
but as i said in earlier post rc dosen’t take full advantage of the ssd’s on the temp drive, so even a large single ssd would be ok.
pagefile on the other hand i’ve seen use up to 1500mb/s which is about 50% of what the array could do.
coming from doing a lot of 3d work (mostly still, but some animations too). I find doing photogrammetry a lot more processor intensive and a lot longer wait times to what I’m used to. (and i have some really long render times). as well as having only 1 pc instead of being able use our small render farm.
so i would go in order (for large scenes with current rc version and licensing, ram usage could change to need a lot less, and network processing may change the setup drastically)
Ram
Cpu
GPU
SSD
in a future rc version that included network processing for reconstruction phase i could see having a pc with a few gpu’s to make the depth maps and the rest being fast i7’s would be a better setup. but i also think RC ram usage probably also needs to get under control a bit for this to be practical.
