Wolfe & Libertad is part of Laisvie Andrea Ochoa's artistic research
for her Master of Choreography study at Codarts/Fontys.
I'm involved in the creation process of the live video projection mappings used
during the performance of this dance.
The piece was first performed on July 2, 2019, at Theater Rotterdam Witte de With as
part of the
#1 COMMA festival.
Wolfe & Libertad explores the relationship between the digital presence (Wolfe) and
live presence (Libertad) of the dancer.
In the dance, the body is a shared territory for movement and image. Projection
surfaces are formed on stage by the dancer's body.
Projection surfaces on stage are detected using the infrared depth-sensing
capabilities of a Microsoft Kinect.
I've developed an openFrameworks app which translates raw depth data of the Kinect
to stills or live video frames that can be used as a mask layer for the projection.
By applying minimum and maximum depth thresholds, it's possible to filter out
surfaces at specific positions on stage.
The generated mask layer is shared via Syphon which is used live by Laisvie as a
mask layer in Modul8.
Using infrared lighting for surface detection gives Laisvie the ability to generate
mark layers on the fly, even when the stage is pitch black.
During the development of the piece, this ability was required for a scene where the
dancer would crumple a big piece of paper in the dark.
This big crumpled paper ball formed by the dancer became a projection surface with
an unpredictable shape and size.
