Perspective Lyrique / MadMapper

Posted in MadMapper, Perspective Lyrique, video mapping with tags on December 11, 2010 by Francois Wunschel

After a SSD Laptop crash, finally I took some time to snapshot the Madmapper+ QC + Ableton Live + CueMix view.`More to come in the next post ;°).

Perspective Lyrique / on location tests

Hiya,
we just spent all night tinkering our projection, trying to match the actual architecture as close as possible. Thanks to MadMapper, the task was rather easy, although we found a few really annoying UI bugs. Due to some modelling inaccuracies, I had to split the projection in 3 parts, each perspective corrected. Nevertheless, we ended up being roughly satisfied (but ya know the tune… I can’t get no …).
Then we took a few photos on location. And as usual with video mapping, the parts you design the quickest are the best…

Here’s the building relighted in 3d (Ambient Occlusion + Soft Shadows + Toon shader):

And the headshot, fully voice-activated (AO + SS + 8 morph targets depending on the tone of the voice):

And the MadMapper setup:

Tomorrow, I’ll try another Madmapper technique, using either grid warped (but still perspective corrected) or maybe camera pose estimation (with an openGL matrix output-to-file feature, then back in QC).

Perspective Lyrique / Headbuilding

And finally the headmap applied on the 3d model, morphing-ready. The audience will be able to sing a few phonemes in realtime, and also a few expressions, like fear, smile or anger. I’m eager to see the end result projected on the building, as there’s a chance it might look like crap. Pertinent video mapping is always difficult to achieve.

Perspective Lyrique / FaceMaps

Today I’ve been rendering facemaps for our interactive video-mapping in Lyon, next week. And I just happen to like them as-is. The first one is quite minimal, and the second one somehow reminds me of the famous JoyDivision record sleeve.

Perspective Lyrique / from building to head, then explode

Posted in event / project, Perspective Lyrique, video mapping with tags , , , , on November 6, 2010 by Francois Wunschel

Since I can now “somehow” rely on MadMapper for the technical aspects of 1024’video mapping projects, I’m happy to focus a bit more on content creation. Back to the roots.
For Perspective Lyrique, a mapping we’re doing in Lyon, Fr, for the “Fete des Lumiere” (aka Light festival), I’m developing a realtime morphing application, that will transform (according to the audience voice) the actual building into a crying head, then eventually we’ll explode it.
Here’s the sequence (snapshotted from realtime QC).
Freaky ?
