experimenting with smoke holograms

Since I developed the Dream Bubble Machine I`ve been fascinated by the idea of using smoke as voluminous projection surface and was very happy when I then saw this video of japanese scientist using a smoke column as a holographic multi-viewpoint display. Then I thought there could be an easier way to achieve the same result fixing the smoke in a solid shape and using one projector and a mirror system.

I used the visual programming environment VVVV to build a simple virtual setup of rendering a 3D object from slightly different angles and then projected it on a plate with adjustable mirrors which were focussing the images again in the center of a glass bowl filled with smoke.
