New plugins to aid nadir/zenith retouching

Over on the PanoToolsNG forum, Rune Spaans has just announced the availability of two Photoshop plugins to help with nadir/zenith retouching. Starting with an quirectangular panorama image, one plugin remaps the two polar regions into side-by-side rectilinear projections in a new layer. The other remaps the edited images back into equirectangular format for merging with the original panorama. The views extracted can be zoomed in and out. 8 and 16 bit images are supported, but on Windows only. see: www.superrune.com/technical/software_spheretocubi...

Thanks John for the post.
Just tried it.
With this plugin it only allows you to create the nadir and zenith for patching purposes and then convert back to an equirectangular projection. Then you still have to create your QTVR with whatever software you have.
If you already have Pano2QTVR... stay with Pano2QTVR. With Pano2QTVR you'll have the option to fix any sides, not just the nadir or zenith, if needed. Then you can create your QTVR. For my workflow it's not worth the extra step. Just my findings.
This would probably work with other workflows...

Hi,
I just uploaded a quick guide to how I use the plugins.
The plugins were mainly done for 3D artists (like myself), who create equirectangular panoramas for background environments. But it would be cool if someone else found it useful (I've got plenty of enthusiastic emails from panorama shooters so far) 
Cheers,
Rune

I find PTEditor much more convenient. Edit the equirectangular and then produce the QTVR with pano2qtvr. No tiles to worry about and edit any view from the equirectangular image, not just the six 90 degree tiles in a preset position. Each person will discover a workflow that suits them best. It's good that we have such a choice of ways of doing things - and now a new one from Rune. It's horses for courses.

What do you do when the equi is greater than 10000pix?

Rosauro, I don't normally generate equirectangular images greater than 10000 pixels. I never need more than 5000-6000 for fullscreen panoramas.

superrune, had a look at your website - some great stuff you have produced! Great to read about how you made the Raytracing on the Amiga as well, I remember trying to model the red/white Amiga chequered ball. :P
I must fire up Max again and start making more stuff!

Sorry about the downtime, my ISP had some hardware issues and the page was down for a couple of days while they restored backups.
I've updated my plugins to version 1.1. There's plenty of changes, have a look and let me know what you think:

Having used this plugin I find it does not convert from cubic to spheric properly with Photoshop Elements 5, I don't know if its a bug or not.
Like John I prefer to use PTeditor, so much more flexible for outputting the exact view you want to work on.

No problem, I am not forcing anyone to use this plugin. If your happy with what you're using, why change at all.
I don't have Elements, so I can't see what it does to my plugin. Sorry about that.

Just a quick note to say THANKS
I have tried the plugins and really like them. In the past I have used PTEditor but your plugins save me loads of time.
Cheers
