Testing a motion controlled gold dust particle/interaction for an installation. All particle interaction is controlled entirely by motion on camera. Most of the fine detail is lost in the video compression, you can see much more in the original quicktime.

“Gold” is an interactive installation which explores our obsession with super-stardom, and the extravagance that accompanies it. Through a ‘magic mirror’, revel in a world of excess where you are the super-star. Shower in glittery gold, experience almost omnipotent powers as you materialize, morph and dematerialize into pure sparkling gold dust. Immortalize yourself as a shimmering golden statue, before you collapse and disintegrate into the wind.

The installation uses custom software written with openFrameworks and the OpenCV computer vision library. The software analyzes the video feed from infra-red cameras in real-time and generates 1080p HD output using OpenGL.

Source code for the particle system in this demo (minus the fancy effects) can be found atmemo.tv/vertex_arrays_vbos_and_point_sprites_with_openframeworks This demonstrates how to use VBOs, Vertex Arrays and Point Sprites for sweet sweet performance enhancements.
