Excellent tutorial Carl. Just one comment: the plans (layers) are reversed. Note on the NO TURNS and NEWS ROOM text.
All the Best.

Okay. This is freakin' brilliant. I've done documentaries in previous years using Electric Fish's QTVR Matte, but it's orphaned, it's OS9 and AE 5.5 or earlier and it was slow. I've just offered up a test to my client and although it needs a little tweaking, it's a far cry from working from a 200MB QTVR file on OS9. Thanks, Carl!

Excellent Tutorial Carl; not only did I try it with the images you provided but then tried it on several images I found for Toronto. I learned quickly not all images are created equally - some line up better than others.

For readers, there is also another tool you can use on the Windows platform that's free for converting to cubic, look for Pano2QTVR; it costs if you want to make movies but free to use if you just want to convert to movies; just google for it. Worked perfectly.

How do you export faces using Hugin
by Phil LeBeau
I was trying to figure out the Hugin software - but i cant seem to export my photo in "faces"

Multiple Cubes, Bigger World?
by Garrett Unglaub
If I took multiple cubic panos at set distances, could a bigger world be created? Create a flythrough of a house? Or explore a city? Is that possible? Seems like you could just link the cube faces, or it could turn into something ridiculous and complicated..

But how cool would that be?
Free equirectangular to cube face tool
by Roger Howard
Just wanted to add that if you need to generate cube faces and don't want to spend any money on it, you could easily do this in Hugin (an open source panoramic suite), by using the command line tool "nona" (which also comes with Hugin or can be built on its own), or with PTStitcher (part of the Panotools open source package).
real time preview
by Daniel Hoffman
As I follow along with the tutorial I run into one issue. Once I have my world created and the camera is inside the cube, as I rotate, my view doesn't rotate with me. It waits until I have unclicked the mouse and then rotates to that spot. Is there something that I need to turn on in order to get a real time view as I rotate around my world? I hope I'm explaining this well. Any help is much appreciated.
Thanks!
Free option?
by Roy Kristiansen
Hi.

I`m wondering if there is a free option to "Cubic Converter" (witch is 99$, much for a poor student) or the panocube (10$ is cheep, but didnt like the program.) I`m using a mac.

Thx alot for the greate tutorial. Keep ut the good work !

Hello Carl,

Awesome tutorial but am not able to test it :(

Panocube Software is throwing up some bunch of virus(s) in virustotal.com. Not sure if it is false positive? Any idea?

Tx,

Building a Cube World: Part 1

You're on the right track.

The images are in fact being scaled up far beyond 100%. But, they're also getting proportionally farther away from the camera. So, "to the camera", no pixelation is happening and everything renders perfectly.

Andrew Kramer has a fantastic tutorial that demonstrates a similar camera principle (scaling above 100% with no image degradation) in his 3D compositing tutorial here on the cow.

Building a Cube World: Part 1
by Andy DeVries
Is it the fact that as the images are being scaled, they are getting proportionately further from the camera, thus preventing any distortion?

Okay, that's my last guess. I will wait for someone smarter than I to answer.
Building a Cube World: Part 1
by Andy DeVries
I do see that the images are not being scaled at all, yet they are being parented to a null that is being scaled...I'm really missing something.
Building a Cube World: Part 1
by Andy DeVries
but if the cube faces are being scaled, that would mean the images are being scaled, too...and the images were brought in to a same-size comp, meaning they're being scaled above 100%. I realize this can't be, since a %1000 scale would destroy the image quality, but I'm can't seem to wrap my head around how its working.
Building a Cube World: Part 1
by Carl Larsen
Scaling up the world scaler null makes the cube larger. As it scales up, the cube faces move further away from the camera, making the corners of the cube appear flatter to your eye. Once the cube faces are far enough away, your eye can't tell the difference between being inside of a cube and being inside of a sphere and the trick works.

1000% was just an arbitrary number that seemed to work well at the time of the recording. Any "large" number will suffice.
Building a Cube World: Part 1
by Andy DeVries
when you scale the "world scaler" null to 1000%, what exactly is that doing? the world does appear to get larger, but obviously scaling the images themselves would cause distortion.

Great tut, thanks!

Equirectangular photography tutorials?
by Garrett Gibbons
Great tutorial!

Now I want to stitch my own equirectangular shot. Anyone know of any resources to stitch the photos? Or a how-to, tutorial, or anything? Google yields mostly images that are equirectangular, or how to use them in a similar way, but I haven't found anything about stitching your own.

Thanks!

I think more information is required for the process of creating the 360 degrees panorama.
Can this be useful?

I'd like to throw in that cycore has a plugin called CC environment, when applied to a layer it works with a 3d camera as a 2d layer using an equirectangle map

just another plugin that deserves it's due. Works well.

still the creating a cube and using it as an environment map, well i was very surprised that worked so well, more cow 4 you.

Wonderful tutorial. Can't wait for part two. Thank you!

Jerry -

Thanks for the comments. It is possible to do the equirectangular to cubic conversion in photoshop, but as far as I know you can't do it using the built in tools alone. Instead, you need to buy the $30 LensFix CI / Panotools plug-ins from Kekus Digital -There are probably other approaches out there, but I'm not aware of them at this time.

If you choose to pursue the Buy LensFix CI / Panotools plug-in route, here's a link to a very useful tutorial on the subject:

http://www.all-in-one.ee/%7edersch/panorectilinear/panorectilinear.html

If you are feeding the plug-in a full 360 equirectangular image you'll have to run the plug-in six times with the following settings to get your cube faces.

Image:
HFov: 90
Width: 2000
Height:2000
Format: Rectilinear

Panorama:
HFov: 360
Width: 0
Height: 0
Format: PSphere

Position:
Yaw: 0 Front, Top, Bottom; -90 Left, +90 Right, 180 Back
Pitch: 0 Front, Back, Left, Right; +90 Top; -90 Bottom
Roll: 0

Two final thoughts: You may be able to find a script out there that does all the data entry for you, or you could record an action within photoshop to do the same thing. Personally, I think cubic converter is a slicker method for an 8 bit workflow, but you may have to get the plug-in if you find yourself in a 32 bit pipeline.

Hope that helps!

Hi, good tutorial. Especially being that its free. I never go into using pano pictures in AE but I always wanted to. I was wondering though. Could you use Ps CS2 or higher to do the cutting up of the pictures. Thanks for you help.

When a project requires a photo-realistic 3D world, After Effects isnt usually the first program that comes to mind. Typically a 3D modeling/animation program is necessary to create virtual 3D worlds, but in this article CreativeCOW contributing editor Bill O'Neil demonstrates creating a 3D world for a TV spot he was hired to direct and post for the Big Ten Basketball Conference.

mocha Tracks The Wolf of Wall Street

mocha Tracks The Wolf of Wall Street

With multiple VFX Oscars (Hugo and Titanic, plus a nomination for Apollo 13) plus a couple of Emmys (Star Trek: The Next Generation and Star Trek: Deep Space Nine) under his belt, the most remarkable thing about Rob Legato's latest VFX extravaganza is that it doesn't appear to have any VFX at all! Martin Scorsese's The Wolf of Wall Street is a masterpiece of what has become known as invisible effects, and this article from our friends at Imagineer, highlighting Rob's work with mocha, is a real eye-opener.
