Abstract
Embodiments of the invention provide a method for visually designating a plurality of points in three-dimensional space using an apparatus including at least one laser configured to emit visible light, at least one lens configured to collimate the visible light emitted from the laser, a plurality of independently controllable reflective surfaces wherein each surface is configured to independently steer a portion of the collimated visible light dynamically in time, and a control means configured to adjust the steering of the collimated light. The method includes selecting a plurality of points on an arbitrary plane. A portion of the collimated visible light is steered to locations corresponding to the selected plurality of points on the arbitrary plane. And, at least one of the points of the plurality of points is illuminated with the portion of the collimated visible light. Alternatively, a plurality of non-planar points is selected in the three-dimensional space.
