Well, there you have it! Thanks for clearing this up for me Hans! Definetely saved me some money there on extra drives which would have been ill spent.
BTW, do you know of any good programs to use for these projection conversions?

It sounds to me that 33h is extreme and maybe can't all be explained by too little RAM or disk space.
Can it be a problem with some of the individual images? Control points? optimization? They're all Jpegs and the output format is PSB with layers and blended panorama.
Another thing with this particular panorama is that it's centered on the nadir, i.e a "little planet" panorama. I don't know if that has any impact on rendering time though. The size is appr. 15000x15000 pixels.
Thanks for all your input!

I run PTGui 8.2.2 at the moment but I downloaded 8.3.1 a couple of minutes ago. I def. will try it and see if it makes a difference.
The machine I run PTGui on at the moment is a dual core 2.67 GHz with 2GB RAM and win XP. Not the latest but not 7-8 years old either.
I know that we will go over to Windows 7 during 2010 and then I could put in some serious amounts of RAM for PTGui to use. But at the moment I'm stuck on a 32 bit Xp machine.
At home I have a quad core with win Vista 64 bit and 8GB RAM and a couple of TB of disk space on three harddrives. Maybe I can borrow a license and do some work from home, i don't know the limitations of the PTGui company license though, I have to check that first. And I probably have to go Pro to be able to use more than 2GB RAM as well?

I recently set PTGui to do a panorama of about 40 12 Megapixel images. It warned me that it needed 105 Gb free disk space and I only had about 90. But I couldnt free up any space at that moment so I set it to work anyway.
The whole process took over 30 hours!
I know that the limiting factor is disk space when rendering panoramas with PTGui and not cpu, ram etc.
How can you (and how have you) optimize your machine for panorama work, especially for high resolution panoramas?
I've been thinking of a couple of SSD drives in some RAID formation, but maybe there is a simpler and cheaper way? I probably can setup a dedicated machine to do all PTGui work from an unused computer and on that have a couple of ordinary SATA drives with alot of free space.
Any thoughts?

I'm soon going to get my NodalNinja hardware and will be experimenting alot whith all that is panoramas then.
For now I'm going to use my Canon 18-55mm kit lens in 3 rows + zenith/nadir.
Right now I'm allready starting to see problems on the horizon though. How will PTGui be able to stitch my +45degree photos as they are more than likely to be covered in blue sky or clouds? Is there any trick to this or do you manually have to position them correct in PTGui?

That is exactly the same as www.hdrlabs.com/tools/panocalc.html and not the one I was looking for, but thanks anyway!
I guess you could use that calculator to calculate the tilt angle as well by changing the FOV and the desired panorama FOV from 360 to 180?
Still, is there anybody who has seen a calculator that you basically enter your lens and camera model and the calculator tells you exactly how many pictures in how many rows are needed for a full 360 panorama?

Thanks bigwade for the link, I bookmarked it immediately! It's unfortunately not the calculator I was looking for...
It was something more like this here: www.hdrlabs.com/tools/panocalc.html but with the difference that it also showed the needed tiltangle and the total number of pictures in each row.

I think I stumbled upon a calculator on a site that helped you calculate the required angle between the photos both vertically and horizontally. Now I cant't remember where I found it.
You could choose your camera and lens from a list and your desired overlap, then it calculated both the angle between photos in each row and the angle between rows (tilt angle).
Have any of you seen that somewhere??
Thanks for your help!

Just discovered the same hanging problem with Firefox v3.0.11. I didn't have the same plugin as you but disabling another Java plugin fixed the problem. The addon was "Java(TM) Platform SE 6 U13". Don't know yet if disabling this addon will cause other problems though...

Beautiful panoramas Dorin! And thanks about the tip about NodalNinja both you and Rosauro!
Dorin, the panoramas you made with the 18-55 lens, how many pictures did it take?

Hi everyone!
In my work I often produce photomontages of how, for example, windturbines would affect the landscape from a given point. Right now we only do these photomontages of single or sometimes of 2-3 stitched images to get a maximum of around 160-180 degree view of the landscape.
Now my goal is to be able to do full 360 panoramas and offer these as a qtvr movie. It doesn't have to be fully spherical panoramas, cylindrical is enough (for now).
I work with a Canon 450D (non full frame) and a 18-55 mm lens.
One of my concerns is if I'm able to work satisfactorly with this lens for this purpose? I understand that it will take a lot more pictures to create a full 360 panorama, even more if I want a spherical, but how much more work is it then in front of the computer to stich it all together? Is it a big difference? Is it feasible at all? (I want to get paid for my time, hehe)
If I'm deciding to start with this lens after all, I'll need a panohead that supports multiple rows of pictures. Can you point me in the right direction or maybe you know of the perfect panohead for this setup?
As for software I'm thinking of going with Panotools, not because it's free but because it sounds like a great set of tools. What do you think?
I have tons of more questions but will hold for now...
