Synopsis:
A simple cube made from tag board and taped together. A prototype for an upcoming exhibition demonstrating that a physical sculpture can be projected upon with the image of a 3D model perfectly mimicing the actual shape. Images texture mapped to the virtual cube can line up directly with the real, physical, cube in such a way that the images are corrected for the distortion of perspective. In other words, the virtual texture-mapped cube becomes a real texture mapped cube. In the images to the right a demonstration of this technique is shown, albeit in a primitive way.
The suggestion here is that a more complex 3D object could be created in a modeling program, physically re-created and then projected upon with a texture-mapped image of it's virtual counter-part.
The imagery on the cube is simply a live video stream from the computers built in camera mapped to each surface of the cube. Additional virtual lighting is controlled by LFOs.

This medium has gained increased interest in the international community in the last few years. Below are links to some artists making serious contributions to this field:
HC Gilje
Teemu Määttänen
Pablo Valbuena
Materials:
One video projector; one iMac running Quartz Composer; tagboard, framers tape
The final sculpture will use two video projectors and two computers for complete coverage of the surface.
Dates:
March 2008
Location:
Some basement in Seattle
