General / Re: New Mac pro and PS

I'm also curious about expected performance increases for the MacPro.

Alexey, my understanding is that, depending on the PhotoScan algorithms, if the working set fits in the 30Mb L3 and didn’t fit in the current Mac Pro’s 12Mb L3 cache, we're going to see a big improvement in speed.  Otherwise, the main speed-up is likely to be closer to the ratio of the speed increase of memory, which has been bumped up from 1333MHz to 1866MHz. Can you confirm?

Hello Holger,

PhotoScan utilizes OpenCL devices during depth maps computation step and several GPUs can be used simultaneously (but not in SLI/CrossFire mode). But as for FirePro cards they should not be very fast in terms of PhotoScan performance.

Bug Reports / Re: Importing cameras does not correct alignment

That was exactly the issue.

We use unique batch numbers to separate each set of images we capture. As soon as we changed the camera names to match the new chunk the cameras aligned perfectly.

Thanks for your help!

Bug Reports / Importing cameras does not correct alignment
« on: June 27, 2013, 08:50:05 AM »
I have 60 stationary cameras positioned in a circle around an object. After processing the images for one object the cameras aligned perfectly. However when processing another object with the cameras in the same position they did not align properly. I attempted to correct this by importing the correct camera alignment but the camera positions did not change. Any thoughts as to why importing cameras did not fix the alignment?

Bug Reports / GPU Processing Failed
« on: June 01, 2013, 06:52:49 AM »
Running PhotoScan on a Mac Pro with the following specifications:

Processor  2 x 2.66 GHz 6-Core Intel Xeon

Memory  64 GB 1333 MHz DDR3 ECC

Graphics  AMD Radeon HD 7950 3072 MB

Software  OS X 10.8.3 (12D78)

Durring the Depth Map construction phase the console reads, GPU processing failed switching to CPU mode.

What might be causing PhotoScan to not take advantage of the graphics card?
