Nice feature not everyboduy knows.

[luca vascon]

So, put the case you want to help somebody to stitch a pano and you only have possibility to exchange lo-res images.

Or think you want to work FAST, a LOT of panos in an old laptop.

(I can not think to give up my IBM T60 Thinkpad, a definite NO-NO, I do not want to leave XP for no  reason, and, no, i will never downgrade to a mac, the big machine is @work, and my beloved IBM is what I'll have at home, for next 2years)

Or think you have a 65364376365356 pictures trilliardpetapixel-o-rama in your mainframe machine.

Make a folder with all the images involved

Make a copy folder, with reduced-size images, preserving the names.

(IRFAN VIEW, windows only, can do it in batch for you in few clicks, even copying the whole folder structure, free but not open source)

Build your project with the downsized images.

Copy your project in the original folder and open it...

VIOLÁ.

Set the new size for the final panorama and render.

If you already know the final size of the picture, you can pre-set it while working with the lo-res images.

And then....

... the long-night of batches!!!!

You sleep, your computer works.

I use this trick even coz I have 2 or 3 instances of ptgui opened, on the 2 screens. You know, one is finding cp, while I set verticals or masks on another.... Working on lo-res gives it more responsiveness.

thanks!
that should be great workflow performance improvement!

but i thought ptgui does matter the dimension of the image, itn't it?

good tip man! I have a Macbook pro intel core i5, but it "coughs" previewing the live changes on panorama... thanks!

[luca vascon]

Core i5 coughs?!?!!? Also try to put as much ram as it takes. OSX is resource hungry, far more than my modified XP!!

If the computer is really getting sluggish while using PTGui it might be
that all RAM is being used. Once that happens the OS will start swapping
to disk.

Close any memory hungry applications like Photoshop. Or go to
Preferences - Advanced in PTGui and set the Max RAM % to a lower value.

That said, the Detail Viewer will take some time to update. Please keep
in mind that it is actually rendering a part of the panorama (warping
and blending) which takes some time.

The drawback of this trick is that CP generation (done with downsized
images) is less accurate, leading to not perfectly aligned images when
applying the .pts to original pictures !

[luca vascon]

true. Depends on how much you downscale the images.

I also thought that could be a drawback of this technique.

What would be the quickest way to refine the control points for the
high resolution images? Is there a PTGui command that would help?

Unfortunately not. A "fine tune control points" feature would really be
nice and was requested already years ago...
