53: Dealing with Finicky After Effects 3D Function

     I wasted most of my week trying to get my After Effects Project set up to produce a better high definition version of this low res test  picture I did in the fall as a demo:
    When I finally got the Key picture of the facade the whole Architectural mapping would be based on, I started cutting it up and  putting every single part of it on a separate layer in Photoshop:
  I ended up with about 250 layers: 5 rows of 11 "brick drawers", 26 or so columns, bases, thick and thin tops, thick and thin lintels, 8 light cans, 6 niches, window panes, doors, sidewalk, awning, planters, trash can, etc...
  To that will be added 20 or 30 "objects". 
  All those layers will have to be imported SEPARATELY into After Effects. I tried to import the Photoshop file, and it "kinda worked" at first. I renamed them without the long Imported Titles. 
  In order to animate all of those Architectural Components in 3D and spin them in space realistically, each "drawer" and column front face needs to be Precomposed with a back, 2 sides, a top and a bottom. The final 280 or so "precompositions" will be animated in the timeline.
  I did my best, but then later down the line, shadows just would not render properly. I wasted days trying to make it work, and finally gave up.
  So I just rebuilt the picture from scratch using only the elements needed, making sure asI added elements that the shadows worked, and will deliver it in time for publication in UAB Magazine next week...  It is getting close:

Post 52: Testing the dome

   We almost got rained out again last night, and the structure was a little wet, but we proceeded nonetheless with the test, hung the projector from the top of the dome on the bracket mounted on the threaded rod. I used a grid distorted at the top  into a 1920 x 1080 near circle as a test pattern:

  The results were terrible. The image almost covered the  dome in height, but was sort of pie shape and very narrow on the width, with tremendous distortions and light fall off top to bottom:

  So much for my Bourke Paper based vertical projection concept. Christophe had a problem to deal with on the phone, so things dragged on, and Randy had to leave rather disappointed. 
   Finally, after taking down the projector, Christophe tried HIS more simple concept of placing the mirror in the center of the floor and projecting horizontally, and that actually worked beautifully. The image was in focus all over (a little soft for a still image because of the large area covered, but Christophe could see individual pixels, and moving video should look sharp enough), most of the half dome was covered, there was no light fall off, and distortion was very limited:
   Even the architectural image looked beautiful, with the ceiling edges almost straight and square:
    We were pretty excited. There are some adjustments left to be made for sure (squashing the image about 10% vertically, and adjusting the curvature of the sides to fit the half dome exactly), but I am totally confident now it can work. We could build a 6 ft platform in the center of the big 44 ft PTTR dome to put the half sphere mirror with two projectors on it. The VJ's and computer station could go underneath.
  My 20 ft half dome looks bright enough with one 5K projector, so the whole 44 ft dome would require (5K x 4) x 2 = 40K . So two Barko 20K would be required(or two new 1920 x 1200 Panasonic 20K's that just came out and are half as big and heavy, and require half as much power as the standard Christie and Barko): 
                 Panasonic 20K Spec Sheet
          
  The only difficulty may be to get a continuous seamless image where the two projections blend, though I think this may be a built in feature of the software for those projectors . A black background would make it easier of course:

Post 51:Projection on water

  Tony and I both did some research on the subject today and came up with some interesting videos. Particularly exciting is that Nissan car promotion projected on a 120 ft spray of water:
     The 2013 Nissan Altima 3D Water Projection - Behind the Scenes
  Also interesting is this Ukrainian one done for a party:
Kozyrnaya Picnic Party, Kiev, June 13, 2009. The jewel of the party was a stunning show featuring a hologram, 26 m x 15 m size, suddenly emerging above the still waters of the lake to the surprise of party guests.
   All I can say is whaoooo, they know how to throw a party in Ukraine!
  Another impressive projection on water by Palnoise.org:
    Water Screen Projection @ Ibiza
  I also found the video for the Lyon pictures I posted yesterday:
 3D projection on fountain at 2011 Festival of Lights in Lyon, France

Post 50: Brainstorming session with Christophe and Liesa

  Christophe is temporarily back in town, and came this afternoon to help me make an adjustable bracket to hang the projector from the top of the test half dome my godchild Charles built out of 1" PVC pipe just outside the door in my back patio:


The top plywood assembling plate is attached to the door frame for stability:


 We are going to attach the 1/4 sphere surveillance mirror to it, and hang a threaded rod from the center to mount the projector vertically using this 3 way adjustable aluminum bracket I designed and that Christophe helped me make( I am still stuck in a wheelchair):
It rained, we ran out of time, and we had to postpone the test till Tuesday.
  I asked him if he would be interested in taking on a "Point of Light", for example lighting up Spencer Hall, and he is. So that's great, and I am happy to have him on board.
  Liesa Cole came by with her partner and computer whiz Tony Rodio to talk about about doing their own "Point of light", possibly in 3D. We all brainstormed like crazy over dinner, and they seemed actually more intrigued with the idea of a projection on water mist:

  We had a really good brainstorming session with her, as she kept spewing new ideas... We are thinking of possibly spraying the water down from an arch lined with soaker hoses instead of up from a pool. It just now occurs to me writing this that we could also possibly make an arch above a shallow pool (black plastic tarp over a 2 x 4 frame) with several black PVC pipes pricked with lots of tiny needle holes (using a hot needle) shooting down at slightly different angles. It should create a pretty nice wall of mist to project on, would be cheap to make, and more stable if there is a breeze. We could rent a big electric pump to recirculate the water.
  Whatever Liesa and Tony decide to do, I think I've got them on board too.

Post 49: "Zero Gravity Pas de Trois"

I am delighted to report my old friend Mary Foshee is on board, and about as excited as I am about choreographing a "Flying Dream Light Dance", or "Zero Gravity pas de Trois" as I am to see it performed wearing the EL suits we make. The key words here are "flying" and "Zero Gravity".
I have known her and admired her work since the early 80's, when she was one of the most creative members and Director of "Southern Danceworks".
We didn't need to talk about the project all that much because we were already on the same wave length: weightlessness, zero gravity. I have had recurrent dreams all my life where I either fly like a bird, or simply levitate. So seeing the Russian video struck a chord very loudly, as did the performance from the student group "Fighting Gravity".
As a dancer and choreographer with more than 35 years of experience, that is basically what Mary has been doing, but in broad daylight or under stage light. The man lifts, the woman flies, but you see them both, the mechanics are exposed so to speak.
The black light and the EL wire suits concepts on the other hand create a very realistic illusion of weightlessness, as the lifters are wearing black suits and are not visible at all in the dark. That is what excited us so much: all you see are the lighter dancers up in the air in impossible poses, leaning, spinning, upside down, levitating, flying.
This is what so many of my dreams have been about since I was a kid! This particular "Zero Gravity Dream Point of Light" really means a lot to me.

Post 48: EL suits and Light Dancing

   Then I ran into a dance video on You Tube done by a Russian group that absolutely blew me away. The dancers wear black suits with EL wire stitched to it, and dance in the dark. The effect is amazing, it is pure magic, check it out for yourself:
          http://www.youtube.com/watch?v=GX2TnaZ3LoU&feature=related
 
  A few people have other less sophisticated videos on YouTube, but this is pretty Avant Garde  still, so  I feel it is definitely a MAJOR "Point of Light"  we need to have in our Light Dreams Festival. Nothing could be more fitting: never seen before in Birmingham as far as I know, new technology applied to  dance, an Art Form as old as the world, high entertaining value, a dynamic "Point of Light" next to the static ones, a huge Whaoooo factor...
  Cirque du Soleil uses some similar suits in their Michael Jackson show:
 I have already ordered a full black Zentai suit and 80 ft of EL wire, LED glasses and gloves to make an experimental costume. There are several suppliers of EL wire on the Internet, the best of which seems to be:
                Thatscoolwire.com
   I have also contacted my long time dancer and choreographer friend Mary Foshee, and keep my fingers crossed she gets on board.

Post 47: Discovering EL wire


I was looking into the use of LED lights and LED wire, and in the process ran into that wonderful new invention that is Electro Luminescent Wire:
It comes in various diameters from 1.2 to 5 mm (the 2.3 mm being the best compromise between flexibility and sturdiness),and in a whole range of neon colors. It is powered in AC by a lightweight power inverter fed with AA batteries, that comes in various sizes able to power from 3 ft to as much as 100 ft of EL wire.
I could see one use for our "Light Dream" project right off the bat: glowing wire sculpture. I thought of what Alexander Calder might have done with it, like a whole menagerie of glow in the dark farm animals, or a multi colored blinking circus...
I ordered a 15 ft kit off the Internet to play with, an made a 15" yellow cat that looks pretty neat glowing in the dark:
I used 1/8" aluminum armature wire from the Art Supply to bend a realistic shape based on the photograph of a Sphynx, then bent the EL wire to fit and attached it with tightly wound nylon fishing line.
Now if I could only get a serious Artist interested making a big piece with it...
We could also have a workshop at ARTPLAY and have people make their own stuff, but it would have to be coordinated to make a viable display. A whole zoo could be grazing on the knoll for "LUX SOMNUM"...

Post 46: Making a scale model of Alys Stephens

    In order to test how the projection looks as I work on the show, I built a large scale plywood model of the façade of the Alys Stephens Center. The scale is 1:12, or  1ft = 1".




  I primed it white, then painted it colors matching the actual colors as best I could. I will use the same fabric to make stretched panels for the openings, and hanging panels for the large brick area.
  I tested projecting on it with an image taken from the entrance to the parking lot, roughly where the projectors are going to be for the show, onto which I added a bright color grid lined up with the different blocks of architecture, and a partially made up brightly colored fantasy image:




  As expected, the protruding area of the entrance do not line up, nor the curve. We may have to adjust that. But as long as we place the projectors the exact place the original reference picture will be taken, things should line up on the actual building.

Post 45: The Alys Stephens 2012 Season Closing Concept (April 13, 2013)



  A Global celebration of the Arts through Light, Video, Projection, Animation, Interactive Games and displays, Dance, Music, Art Displays, Art Show. 
POSSIBLE NAMES: 
    "Light Dreams(Are made of this)!"
    "Lux somnum: Light Dreams"
DESCRIPTION:  
   For this groundbreaking Season closing event, for the first time in Birmingham, the entire facade of the Alys Stephens Center will be transformed into a giant projection screen that will display throughout  the evening images subliming and celebrating the union and  intermingling of Art, Music and Light :  a once in a lifetime animated  Architectural Mapping Projection Show created specially to fit the building, an interactive endless flow of changing and moving animated images and videos to accompany the Music, a special old fashion 3D show with cardboard glasses, Luminous Artworks created especially by local Artists scattered on the grounds, light shows on Spencer Hall, a 24 ft immersive projection dome, giant interactive video games designed in cooperation with the Engineering Department, Augmented Sculpture displays, as well as a more "traditional" Art Show inside. Join us outside and inside the Alys Stephens Center for this Season closing unbridled celebration of the Arts through Light.

MAIN ARCHITECTURAL MAPPING PROJECTION SHOW:
   Projection of a 20 minutes Surrealistic Mapped Animated Show on the main facade, deconstructing, reconstructing, rearranging, opening up, gutting, modifying the structure, etc…     
    Part of the show could be in 3D (Anaglyph type using cardboard red and cyan glasses(1000 for $250) that would also be used for other 3D displays and the Viscube. The best are supplied by Berezin.com
   It is critical, since budget allows for only two 20K projectors(giving us about 10 lumens per square foot), that the plaza be as dark as possible during projection. That means covering all the lamp posts, and if possible some of the street lights(talk to the city about that).
   Safety lighting should be concentrated on the ground, using no spill projectors and LED's. Obstacles such as curbs should be highlighted with strips of LED's.
   The cans at the front of the building will have to come down.
   All the openings will be covered using ivory muslin stretched over 2x2 frames(2x4's sawed in half are much cheaper), 12 total for the main facade. The brick will be covered with 120" wide muslin strips stretched between the roof and the lover arcade and weighted down with 10 ft lengths of 1" conduit in sewn pockets.
   The sculpture REALLY needs to be gone… The best position for the projector would be far back at the entrance to the parking lot on a 16ft scaffold(I have one), so it would not interfere with anybody's viewing of the show. The quality of the projection would also be better that way. 
   Using a very short throw wide angle lens would place the scaffold smack on the plaza just a little back to the left of the circle(which we may have to do if the sculpture is not moved out of the way, unless we are willing to accept the shadow it would cast on the facade):
   If the parking needs to be accessed, we could possibly build a truss tower on the tip of the concrete island, or move the scaffold back in the lot(problem with trees).

MONUMENTAL ENTRANCE GATE
   The plywood structure would be placed at the top of the steps at the entrance street side, which is 12.5 ft wide. 

 It would consist of 2 x 8ft tall boxes topped wit 2 flat boxes and a pediment, plus two 18" balls:
   The outside(street side) would have projected images of a gate with name of the event etc…:
  We could also project limited mapped animation on the back side:


   Or it could be used by another Artist for another project, or the engineering students for a game. 5K Projectors should be fine. They can be mounted vertically up on poles to the side of the walkway. 
   After the public has arrived and the show starts, a curtain with a slit could be dropped in the back of the gate to project on the whole bottom area, and still let people in and out.


DOME
   I will be working for the 2013 PTTR on a whole dome projection covering as much of their  44 ft dome as possible. This is a pretty difficult proposition, and will need extensive testing with spherical mirrors to be pulled off. 
  Since the dome is too big and cumbersome to be erected for testing during the year, I am planning to build a smaller, simpler and lighter 24 ft dome out of 1" PVC pipe to run the tests:

  We might just as well take advantage of that fact and use it for our Event. There is a perfect area for it next to the plaza in front of the church: 



                     


OLD CHURCH/SPENCER HALL
   I would like to project on both sides of the church: a larger projection on the front if possible(possibly with paper taped over the red brick), and a smaller on the side limited to the round window. The stained glass would be covered with styrofoam panels cut to fit, or just plain paper.



    The tower could be spotlighted with colored gels on up lights(plain halogen work lights are fine, I have a bunch), and the stained glass lighted from the inside:

 The projections on the two sides would of course be more than just color washes… I am hoping to find somebody to put together a short mapped projection.

FRONT AWNING LIGHTING(street side)
   It would look good from the street if we had up lights with colored gels on the front awning of the Building, and colored gels on the post lights:


PHANTOGRAMS
That is something I have been interested in for years, as a particularly impressive part of 3D. They would have to be projected on the ground with an overhead projector. For details, see my blog on the subject:







   The imageshave to be projected vertically on the ground, and pop up in 3D ABOVE THE GROUND. They appear to float in mid air.


TABLETOP MAPPED SHAPES WITH VJ PROJECTION FOR PATRONS'S PARTY IN COURTYARD
  The planter would have to be moved and replaced with a 4 x8 ft plywood tabletop covered in black cloth, larger if we want to put food on it.
   The projector would be on an 8ft pole about 10 ft away from the table, possibly on top of a round food table.






INTERACTIVE  STUFF IN COLLABORATION WITH THE UAB ENGINEERING DEPARTMENT AND THE 3D LAB OF DR. SONI
 Giant pinball:
 This interactive game was voted most popular by the public at this last Festival of Lights in Lyon, France. A console allows spectators to play.


     
 See about the possibility of splitting the screen and running 2 games at the same time side by side on the big facade, possibly different games, possibly same game with two players.
Touch screen architectural mapping:
 A choice of pre canned images, colors and graphic can be chosen and combined by a spectator on a touch screen console.

 Interactive floor :
   Vertical projection on the ground of the plaza that reacts to the movements of people walking on it(fish swimming, leaves blowing, balls rolling, water rippling, squares lighting up. May be a giant keyboard that lights up and plays music(Tom Hank in Toy Story) with a computer synthesizer(Garage Band).
  The squares in the floor light up when walked on: 

  The fish react to the feet:


The keyboard lights up and plays music. The lights could be a hint and help play a tune:



   The leaves are swept up with a broom:


   The balls are kicked by the feet and bounce on each other:



Vertical projection on smoke.
     Investigate the possibility of projecting on smoke from a smoke machine, either vertically, or at a 45 degrees angle.

Projection on water spray:
  That would require building a shallow pool of water about 15 x 10 ft with a 2 x4's frame and a black plastic dropcloth, finding a pump capable to spraying water through multiple small nozzles to create a water mist about 8 ft tall. The images are projected on it for a very surrealistic cloudy waving effect where they appear suspended in mid air.


 Light stick animation:



    The stick figures I saw in Lyon were made of fluorescent tubes, and lined up across and along a pool of water. The animation made it look like the figures were running down lanes and jumping obstacles.

 LED Sylized figures:
 Again as seen in Lyon last December, a number of LED figures, both very stylized and childish, and more shapely and realistic:



 Also plain boxes with backlit pictures:


A "CINCOCENTO AQUARIUM":

 ANIMATA SYNCHRONIZED PUPPET DANCE
   That is a project by a group at Budapest University called:
             KITCHEN BUDAPEST
  A camera tracks the movements of the dancer using Eyesweb software and makes the puppet follow them. We are hoping to use the Kinect Camera instead with the Cocoa Kinect Application:

 The Kinect camera may have other applications as well, from feed back of dancers controlling the movements of the puppet in Animata, and possibly other interactive games and displays, like the Viscube:

"Mini Viscube" 3D immersive space:
 This is inspired by a visit at Dr. Soni's 3D LAB , and his fabulous VISCUBE:
  The lab setup is too cumbersome to be moved outside, so I am envisioning a simplified version set up in the passage under the big awning:

           


   We would need to collaborate with the students of Dr. Soni, to see if they could make a simplified cube work with their stuff. 
   See if we can use the Kinect camera as a motion sensor instead of a hand joystick or Nitendo controller.
   I could possibly supply imagery for an elevator like Alice fall in the hole(see SVANKMAJER'S ALICE)


COLLABORATION WITH LOCAL ARTISTS FOR AUGMENTED SCULPTURES AND ART VIDEOS:
   Joe Wilson, Randy Gachet( http://randygachet.com/index.html ), Karen Graffeo? Janice Kluge? Leaza Cole, Bala Boyd(winner at Alys Beach with a great black and white video)?
   Find somebody that can do live painting on an iPad.
   These pieces can be scattered around the perimeter of the plaza.There is space on the "grassy knoll" by the street for a couple of pieces:




    There is a large vertical projection wall on the right wall by the entrance(can also be used for an interactive game, or live painting), and one in the courtyard(can be only partially used for horizontal projection):





PERFORMING ARTISTS 
     As seen at the Festival of Lights in Lyon, France(Compagnie Zanka:  http://www.labellezanka.com/ ):






     
LUMINOUS BALLONS
 As seen at the Festival of Lights in Lyon, France, these are low cost highly effective points of light:




     




  We would have to use light weight low power color LED's.


LANTERNS IN TREES
   Another low cost effective way to generate"points of light".They can be simple paper or cardboard cutouts with a spot, or shaped paper lanterns with light bulbs inside...
   As seen at the Festival of Lights in Lyon, France:













       
Recycled letters from old neon signs


Alice Tent for Children:
     A rough vision of a white tent and tunnel with projections from the outside? Just an idea for someone to take off and run...
