Attached Link: Polar texture mapping

The attached link mentions how to correct what I'm talking about Mathematically, but is there actual software to do this?

yes, totally something that you can do as a Lua script in Dogwaffle, Artweaver or the GIMP

www.thebest3d.com/dogwaffle/lua   has samples of scripts. I can try and put this algorithm into a lua script.

staigermanus - Thank you very much, dogwaffle 1.11b looks very interesting, but I would'nt want you to go through all of this trouble, I'm sure someone has already been through all of this math?  Maybe we'll get lucky and someone will leave a link to a Photohop Plugin, Action, or other pre-fab software?

Google is your friend. :) The Photoshop Spherical Mapping Corrector by Richard Rosenman is a freeware Photoshoop plugin. And Maxon has a tutorial on creating a spherical texture from Bryce sky for Cinema 4D.

I just converted the algorithm from your link to Lua. I'll post it here shortly:

www.thebest3d.com/dogwaffle/lua/polar

it was a great little exercise. It runs very fast. Lua is super fast as a scripting engine.

You can use the freeware version of Dogwaffle  (v1.2), no need to buy any of the commercial versions. Lua (the DogLua) filter plugin works with the v1.2, the evrsion 2.x, PD Pro 3 and 4 and I think also PD Artist (the $39 version)

O' Wow, Erlik, thank you so much, this even uses the example image of my link!

The DL link at the page you linked to does'nt work, but here is a link to Richard Rosenman's Home/Download page!

Thanks again!

:woot:

I will have to try this out.  I had been using HDR Shop to do that.

1.11b is a bit old now, btw, there's a world of difference between v1.11b from 4-5 years ago and the latest version 4, even 3.7, and even the latest freeware version 1.2 from 2.8 years ago, it's probably like comparing Photoshop 3 to CS2.

I've tested my script with the gluas script and GIMP 2.2, it runs well there too. Though quite a bit faster (make that significatly faster) on PD Pro.

Anyway, this now makes it possible for anyone who can't afford Photoshop to get this function running for free on Dogwaffle, on the GIMP and also on ArtWeaver, which incidentally also has a direct plugin to PD Pro and PD Particles.

Happy scripting!

Bryster scratches his head and wonders what the hell they are talking about.............

TheBryster - This is all about mapping a sphere object without making a seam.  I take you have done much of this?  Have I missed something?

Angel: I have done none of this....or at least very little. I generally mess about with the material editor until I get it right. My problem is that by the time I've finished, I can't remember what I did.

Bryster, there are ways to seamlessly map a sphere using pictures or a panoramic picture.  I usually use HDRShop to do it.

I've also used that to make what I've heard called a "magic cube" which is a cube primitive that is mapped differently on each side.  In fact, you can take a cube, and without doing any boolean operations, open up one side of the cube to see the interior.

It's fun. 

Ricky: Hollywood Effects - a program for generating special effects for movies - uses the same kind of thing for 'transisitions'. Looks great too!

Is it expensive??
