• d146 Experimenting with volumetric video mapping

    Heres a post which is less about day to day happenings but more about one of the many little ongoing research experiments I’m constantly tinkering with. Ive thought about this one for a while but haven’t yet tried to implement this until now!

    After chatting with the Ai guys at work over the past few days about different content/ video mapping scenarios I’ve decided to try and patch sic a thing in vvvv specifically for playing content back on a “Volumetric type video display”. For a description on what the hell a volumetric display is, its basically a video display screen with depth or extra layers which the viewer can see. In most cases a video screen is a single skin surface from a TV screen, projector scene or a projection mapped building. A volumetric display can have depth as well as width and height, heres a brilliant example by AntiVJ.

    Using everyones favourite node based programming software I positioned 4 quads in 3d space at varying depts in the z-plane show in the image above and below. This gave me my basic 3d scene and some reference markers for my camera to look at.

     

     

     

     

     

     

     

     

    Using the same render information from the initial 3d scene I then too 4 views on the same scene, flat onto the relevant coloured quad. From there i then clipped the far and near plane in the Z-depth so that the view was only seeing a shallow depth of that particular plane. This proves the theory of this to be working but I run in to the issue of the model primitive I’ve been using in my scene is hollow, as are most models. Opening up the clipping planes gives a little pseudo thickness but I need to find a way giving the walls of the model a thickness, or the model it’s self some volume.

    Do more research on:

    • Volumetric Models
    • Voxels
    • Shader/.fx to pseudo thicken model walls on the output.

    Its Saturday the 15th February 8 days after the Sochi winter olympics opening ceremony which I’ve been working on and were now working towards the closing ceremony. Its feels a bit strange environment as from what i understand there is a different production company in overseeing the closing but the original production team are staying here as consultants. I could be wrong but there are definitely more people onsite now with what currently feels like less to do overall, I’m sure that will change.  So we had a show, apart from the the ring which did not open that the sensationalist press seemed to focus on the show was FLAWLESS. Heres a picture below if some of the set pieces hung in the hangar before one of the rehearsals.

    Given the time and conniptions out here we shouldn’t really have had as much as we did go right. It was only mid december when we had the storms that blew off the roof in the south hangar which also was unfinished in parts.

    This intern allowed the rain to come in and rain down on the automation carriages used for physically animating the scenery and set pieces in the stadium. Allot of time was spent fixing equipment which to wet and during that time i don’t think anyone could have imagined we would have all that we did in the ceremony. Below is a shot of one of the tracks & carriages in a finished dry hangar!

    Each carriage can traverse through the stadium along, up, over and down the curved roof of the stadium from one hangar to another and carries a 1000kg winch to lift and animate the scenic pieces.

    Below is a hot of South Control where Cam, Davide, Rob and Gethyn have been programming from and then operated some of the show from. Its difficult to tell form the picture but they’re on a temporary platform suspended around 30m above the hangar floor.

    Here is central control opted by  Dan, Neil, Doug and  Paul, although Paul has been kept very busy on night shift going between all 3 operating positions as and when needed! On a side note Neil, over the course of being in Sochi has adopted a stray, one of many which were onsite since we arrived and many have been culled whilst we’ve been here. Given the piss taking amongst the testosterone field environment here its actually quite a noble thing to do and you can read more of the story here: http://www.9news.com/news/world/377034/243/In-Sochi-stray-dog-captures-heart-of-Denver-man

    And then here is south control with Robin, Bruce and Brendon, dwarfed by the huge islands, still now, in pictures, you cannot get a scale of things here, all of the scenery was, and still is massive!!

    After my visa run to the UK mid January I decided to bring my scooter out to get around site, and I’m so glad I did, (a). It saves a load of time getting round site and (b). Its lots of fun. I think just about everyone has had a go on it even the quite a few local Russian security guards. I did on c a couple occasions get some parking warnings, the first was a ticket off Ben from PRG (which I failed to get a picture of, sorry Ben). And then the second was an incredibly well made wheel clamp, which i later found out was off Rory, once of our riggers, hats off it is a work of art!

    Back to work here is a picture of “The Sun” just to try and attempt to show a scale of things, and then when it opens out (iris’s out?) it probably increases by about 1/3 in size.

    And so to the rings, given the outstanding engineering, technology and general perseverance of everyone who made the opening ceremony work, runners, riggers, operators, electricians, lx, video, sound, everyone! . A show which shouldn’t have really happened given the circumstances the press focused on the one thing which didn’t go to plan showing a sad ignorance of everything which went into making everything else work. Heres a good quote from ceremony producer Konstantin Ernst was philosophical about the mishap.

    “Among five rings, one of them didn’t open. And you know, Zen Buddhists have an idea: if you have an ideally polished ball, you have to leave a scratch, to get an idea of how ideally it was polished,”

    Finally, for now, a face which has been right under my nose for weeks, the coffee maker outside the main control room, looks like a relative of Bender of Futurama.

    Final Note:
    Hats off to you Mr Bromagier, you made it work, AGAIN 😉 …….

    I’ve been trying to post here for a while but the internet has been so rubbish since leaving the Raddisson its almost impossible to do anything web based, more on that later.  Its been over 2 weeks since my last update which feels like much longer considering the traveling and work done.  On the 10th of Janauary I left Sochi to return home to renew my passport and renew my visa, this was much easier than expected, Durham passport office were supper efficient  and hats off to them. It was nice to be home for a few days to visit family and catch up with friends.

    Whilst in Sochi, this has been missed, food with flavor! Home cooked meal at my parents, thank you Mum for feeding me up whilst home.

    It wasn’t long before I was on a train to London, flight to Moscow for a 2 hour stopover, a flight to Sochi and finally a drive to the hotel where I managed to get a few hours sleep before starting the nightshift again. There was a fire engine onsite which we had to look at twice,.

    I’m back on day shift now, but had lots of fun with the guys on the nightshift. It was allot calmer on the nightshift, less people onsite and less automation pieces moving meaning we could do more. After the shift we would generally go for a beer or two before bed, this is one particularly sunny day, which we sat outside, sunshine, mid January in Russia!! 

    The lifts are finally working in the stadium now but most of them still have their wooden protection on the inside,  at one point I looked up and saw this.

    Just recently we’ve been moved from the Raddisson Blu, which was quite nice, to another hotel, the Omega on the other side of town which is not so nice. Smithy showed me his bathroom where the plug for the Hairdryer assembly fixed to the wall doesn’t actually reach the plug socket, there seems to be allot of oversights like that in Russia or maybe its just Sochi.

     

    Over the past few weeks we’ve spent allot of time updating firmware at height on gantry’s and in cherry pickers updating firmware and doing general maintenance as the requirements of the show change, and we get presented with scenery which could have been built lighter to hang on the aerial flying system!

    Finally, I saw a face when I was looking in my document wallet which really did make me laugh out loud. It  is one of the immigration forms I got when entering Russia, grrrrrrr.
