Can’t seem to get something to synth right? Curious about what lens is best? Ask your fellow Photosynthers here.
I've shot a couple gigapixel panoramas recently, but ICE can never seem to upload such large panoramas. It always crashes with a memory error around 40% complete when compositing for Photosynth. I read another forum post about a similar problem, and I know that the 40% step is memory intensive. I'm just wondering if it is even possible to complete gigapixel+ panoramas with my computer. I have 2GB of RAM on a 32-bit Windows 7 OS.
How large of a panorama is my system capable of processing? Has anyone been able to complete gigapixel+ panoramas without having a 64-bit OS or more RAM?
This may be a good question for the ICE forum, if you don't get a quick answer here. http://social.microsoft.com/Forums/en-US/ice/threads
Projecting a spherical panorama onto a cube is certainly a RAM-intensive operation, so maybe 2 gigabytes isn't going to cut it. I will say that 32-bit Windows is capable of using up to 4 gigabytes of RAM, if you want to make a smaller investment and just upgrade your current machine.
That will still only allow 32-bit Windows to give 32-bit apps (like ICE) 2 gigs of physical RAM to share while the operating system uses the other two, but if you've enabled the maximum size for Windows' paging file, each app will be given a 4 gig virtual memory space and whatever won't fit in physical RAM will be written to the paging file on your hard disk. There's even a setting for Windows where you can switch the RAM balance for 32-bit Windows so that Windows uses 1 gig for itself and uses 3 gigs of physical RAM for apps. I don't know for a fact that 32-bit ICE is written to take advantage of that 3GB switch, though.
Depending on the ICE team's advice, it may just be time for a 64-bit computer, especially if you want to seriously focus on gigapixel panos or very large synths.
