A digital micromirror device ("DMD") is used to alter the shape of light that is projected onto a stage. The DMD selectively reflects some light, 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 follows 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

Micromiroir numérique pour modifier la forme d'un faisceau lumineux projeté sur une scène. Le micromiroir numérique réfléchit sélectivement une partie de la lumière, modifiant ainsi la forme de la lumière projetée sur la scène. La modification découle d'une image dont le traitement modifie la forme de la lumière projetée en fonction des effets de traitement d'image. Selon une réalisation préférée, la projection suit l'artiste et l'illumine en adaptant la forme de la lumière à sa forme, créant ainsi un faisceau de poursuite sans ombrage.
