Klaus, I think I would be fine with 8gig of RAM if I had 8gig.. but as you know, my iMac has only 4gig of RAM and it cannot be extended.. 45 images is just too much.. but I think my VR Drive captured a few more than that.. I tried heaps of times to process my images but my iMac just locked up.. apg took the images really well, but failed to process them.. I even left it all night.. ;( Its not just RAM which is the issue, a Mac Pro has probably got quad processors.. I only have 2.9 GHz Intel Core 2 Duo.. its fine for most of what I do... Just not high rez panos.. or 360 videos even if I had the camera gear...
45 shots as JPGs must be possible with 4GB and a fast external Temp-drive via Firewire or even USB.
Regarding the focal-lenght of 35mm and the according angles 45 images @20% is the number.
If your VR2 shoots more than 45 or 48 then thereÂ´s an error somewhere. With 25% overlap itÂ´s 48 shots - no matter which head: the positions/angles are defined by the focal-length and sensor-size only. ThatÂ´s definitely independent from the head.
I compared a Dr. Clauss Rodeon, a Seitz VR2 and a Panoneed - all three heads did exactly the same amount of shots. Which is
I processed 45 shots even when i had only 4 GB in my MacBook Pro before i upgraded to 8GB. So iÂ´m quite sure it must work.
But really helpful is a fast external temp-drive of preferably 1 TB.
Did you try it with imported xml?
I again strongly suggest 1) a fast external drive, free for temp ONLY, 2) no other programs running while APG runs and 3) at least free 100GB on the internal - system - drive. In the presets for APG define the external drive as temp-drive.
these measures definitely will help!
