Abstract

Three-digital micromirror devices ('DMD') are used to alter the shape of light that is projected onto a stage. The DMDs each receive a primary color and selectively reflects some light of that color, thereby shaping the light that is projected onto the stage. The control for the alteration is controlled by an image. That image can be processed, thereby carrying out image processing effects on the shape of the light that is displayed. One preferred application follow the shape of the performer and illuminates the performer using a shape that adaptively follows the performer's image. This results in a shadowless follow spot.
