Guys, I´m very excited to show the latest work we did at FireGrader (http://www.firegrader.com)!
We´ve just delivered four full 3D 360° panoramas for Eplehuset, one of Norway´s biggest Apple products reseller. How cool is that? :)
But let´s cut to the chase and see the results:
Eplehuset 360° panoramas (http://www.firegrader.com/site/portfolio/eplehuset/)
All the environments are 3D, except for the backgrounds and the people, which were post produced in place afterwards. The most scary picture was the car, because the people would have to be very close to the camera and to the top and bottom edges, which left us with a lot of distortion to deal with in Photoshop. But in the end, after a lot of trial and error, everything worked out just fine. ;)
Last but not least, a huge thank you to Ondra and the whole Corona Renderer team for introducing this feature in our favourite render engine. Keep rocking!
We hope you like it. Critics are always welcome.

Hi,
well done, especially the integration of people in post.
Could you give us a slight inside in this particular workflow?
well done!
-
Totally agree with Belly. Very nice human composition.
-
Wonderful, so real renders ! Same question as Belly about the people integration !
-
Good work... So realistic...

I'm glad you liked it. :)
During the photo shoot we were always double checking the model's pictures in PS, to make sure that the light and perspective were matching. You spend some time to make this quick tests on set, but you save tons of time in post production later.
Comparing to a standard workflow (not 360º illustration) the only thing that was different was the distortion we had to add to the models. We did it using the Warp function in PS, no big deal, but the 1 million dollars question was: how much distortion should we make and how should it look like?
We needed a real distorted picture from a 360º camera that was roughly at the same distance and position from the models. Since we had all the scenes under 3D development, we posed some bipeds roughly in the same position the models would be and rendered it out.
We also took a 360º camera to the photoshoot (Theta S) and clicked a panorama there as well.
In the end, we had two very good distortion references that guided our warp distortion post afterwards.
The only person that needed more work was the little girl, cause she is very close to the camera and her legs are very close to the bottom of the image, adding a good amount of distortion to it. There we needed to use a second picture of her, from a higher point of view and with the camera pointing down, so that we could get more "legs" to work with in post. So, the picture you see is actually made of two pictures, one from the waist up and othe from the waist down.
I attached some reference pictures of the process, hope it helps to understand it. ;)

That's pretty crazy :] 2D elements integration is really well executed, but wouldn't it be easier to convert equirectangular projection to rectilinear, do integration and convert back to equirectangular? Although in the car scene it probably still could be problemtic, as girl may not fit into rectilinear image entirely, due to very close distance to camera.

We haven't tried that. We figured out that the distortion wasn't too bad to recreate in most of the pictures so we stopped researching when we found a solution that we could have full control over it..
But, with this solution you mentioned, you'd still get a lot of distortion, right? I mean, it is virtually impossible to flat out a 360 panorama without getting distortion somewhere, isn't it?
-
The way you add those people in to the scene, looks quite nice. I must say that its easly the best 360 people I have seen so far.

Not really, equirectangular to rectilinear conversion gives you 6 distortion free images with 90 degree FOV each. It's basically the same if you'd setup 6 cameras facing top, bottom, front, back, left and right render all them and make spherical pano from this six images. Before Corona that was how i used to render panoramas :]
-
This is crazy! I think that the easiest way would be what Romullus wrote - rendering to cube maps. Or converting the spherical render to cube maps, and then back to spherical. But that's interesting nonetheless. How about some tiny making-of? :)

That's the hell of a compliment! :)

Aha! You mean cube maps! That could be another way to do it. As long as the models don't fall out on top of a cube edge, this could be indeed very interesting. But I have no idea on how to convert a cube map panorama into a equirectangular one though. Can Photoshop do that?

Right? That could be cool. We do have more "making of" material lying around. Maybe we should try and arrange some time to do it? Stay tuned. ;)

Natively no, but htere are tools for photoshop that allows convertions. Here's couple: http://www.superrune.com/tools/supercubic.php and http://www.flamingpear.com/flexify-2.html

Great tips, Romullus! Thanks for sharing! ;)
