Convert Cylindrical pics to Cubic pics

Postby Dalton » Fri Apr 11, 2008 3:27 am

Is there a way to do this? Maybe a program or something :?:

Correct me

Correct me if I'm not right (I haven't looked deeply into the topic yet) but I guess there is no such program. Just guessing from looking at a cylindrical picture. I guess at some places the cubic one would be blurred or points would be missing. But just a guess...

You are right Harvester. I would suggest re-rendering as a cube...

The cinema 4d doesn?t have support for cubic photos, only for cylindrical...
So, it?s gonna be cylindrical. Thanks everybody. :D

You could render each picture of the cube by yourself Dalton... You need to render 6 images with a view area of 90 degrees.

This program claims to do that - http://www.clickheredesign.com.au/cubicconverter/

Yes, I've seen that software, too.
But as Harvester said, there is no easy way to convert cylindrical images to cubic ones
Converting cylindrical images or movies to cubic format will of course leave black gaps at the tops and bottoms of the panorama (quote from the software site)

I think that editing those images after the conversion would take much more time than leaving them as cylindrical, or to re-render them to cubic ones...

It would just be really a pity if your images lost of their quality due to a conversion, Dalton, as they are really phantastic :)

I don't us Cinema 4D, but in Vue d'Esprit 6 Infinite I make my cubic panos using a technique that I think should work in almost any program that allows both rendering and animation.

I set up my camera PoV with a 90 degree FoV. Then I set up an animation. For consistency, I always face the camera to the "Front" on keyframe 0. At the 1 second mark, I make keyframe 1, leaving the camera in the "front" position. At the two second mark, I make keyframe 2, and turn the camera "UP". At 3 seconds, I make keyframe 3 and turn the camera to "Down". I continue doing the same for each successive cube side until I reach keyframe 6. Finally, I render out frames 1-6 of the "animation", using a rate of one frame per second and with each frame saved as a PNG image. I save as PNG's because I often do postwork or simple touch-ups on my images after rendering and the PNGs are "lossless".

Finally I post work the images if necessary, then resize and convert to JPGs. To use in AM, just use GM's Cubic Panorama Image Combiner, which comes with the plug-in.

Hope this helps.

Great Tutorial Dalton, thanks (Maybe we should move this to Post Your Own Tutorials)

Well, PNGs are compressed as well as JPEGs. The only really lossles and uncompressed format is BMP.

Thanks everybody. :D
The Cubic Converter is for Mac OS X, so i can?t test it.
The problem to render each picture again is because i?ve already rendered a lot of pictures in cylindrical (11 locations in Orvalho Negro), and took a lot of time to render (each photo took about 2 or 7 minutes to render in my PC). Maybe if i use the ideia that i had about the background image like Phantasmagoria... but i think i can?t do this, because i?m using the cylindrical pluguin in the AM...

2 or 7 minutes

Postby Harvester » Sun Apr 13, 2008 9:20 pm

2 to 7 minutes??? If I would have those short rendering times I would be the happiest person on earth (with such quality as your pictures). I think otherwise that your game looks nice even with the cylindrical panoramas, so you don't need to change it, but that's just my opinion.

But the problem is the Orvalho Negro is not in full screen, that?s why the image looks good. I would like to make in full screen.

See

Well, I see then. After all, cubic panoramas look really nicer... propably worth a rerender? Depends on what you want to do with the game.
