Snow Fall

Virtual snowflakes were projected on a wall of 10 metres: these flakes moved falling down like real snowflakes. When a person came between the wall and the projection, a shadow was created on which the virtual snowflakes slowly settled.
Flake after flake, the snow also fell on the floor creating a white carpet with a distribution very similar to the natural one.

Technologies
The installation is composed of a computer linked to 3 modules, made up of a video projector and of a videocamera sensitive to infra-red rays. The software created for this installation uses a generative code to draw and move the snowflakes in a realistic way. It was also developed to create interactivity between projections and shadows.
In order to have a correspondence between real shadow and silhouette, on which snowflakes stop, the software is comprehensive of a module for the mapping of the projection surface, and of a module for the mapping of the videocameras.
The system was entirely planned and realized by fuse* creative_lab.
