Blender used in a projection mapping in Barcelona


Carlos Padial reported about recent performance art project where Blender was used in 3D content generation for a large scale projection mapping project in Barcelona.

Carlos writes:

I had been working in a projection mapping on the facade of Barcelona City Council during Mercè' 11 Festival (Festes de la Mercè, September 2011) Blender was used along with 3dMax, Maya and After effects.

All 3d stuff in the video games scene was modeled and animated with blender, also some backgrounds and even some dinamic painting to simulate the wet from the rain (10:30, but hard to appreciate)
You can see liero's 3d Pix script in action in the videogames scene (the pacman, 7:20)

I also used blender to make some fast compo setups with audio sync for the running painters scene (01:10) before to recompose it in AE (workflow mandatory circumstances ;P)

There is another show where we used blender, a performance of the Swan Lake Ballet, also with projection mapping over a fountain, where at least 3 scenes were made using Blender. Blender was also helpfull managing pointclouds (along with meshlab) and fixing model issues (specially with the Ciutadella Font model)

Here are two other movies the first a zoom shot and the second a wide angle shot of the performance. At 7:30 you can see the 3D part seen from a distance.


  1. WOW! That was truly wonderful! How imaginative and brilliant an idea, brought into actuality with terrific follow through. I am stunned by its beauty, and thankful for the inspiration. Blender is a most powerful artistic tool in the right hands. Thank you!

    I think this is the best building projection mapping I've ever seen.
    I would realy like to know how to produce the video that will be projected in relation to the building geometry, the audience place and the projector place, so that the audience can feel this "trompe l'oeil" effect.

  3. beautiful. i think these projections work best when doing the deconstruction and reconstruction of the architectual elements, playing with shadows and shapes of the actual building you are projecting on..  that makes it always feel like "whaaaat??"

    not so much fan (even though the sheer size must be amazing to watch) of the way how it's sometimes just used as canvas, and not as building..  for example the splattering of colours etc..

    but.. amazing work.


  4. Wish I could have been there. Would have been even more awesome than matching it here. Also, I could have told all those crazy people that flash on their cameras won't make a picture of a projection look any better.

  5. Astonishing work!

    Btw good job blendernation, not so long ago some very amateurish videos made it into front page news but nowadays every entry is worth checking out!
