convergence

1. The alignment of multiple projectors to form one seamless image.

2. Particularly when referencing music events, a buzzword since about 2002, refers to the combining of lighting and video into one entity, brought about in part by the popularity of media servers such as Catalyst, Axon, Hippotizer, and others. While some would argue that a Lighting Designer/Director has enough to worry about without deciding what image is on the video screens, most agree that the entire visual picture should be under the control of the Lighting Designer. LED screens have found their way into much more than just Imag screens on the sides of the stage, and often are used as scenery: riser facings, shapes forming a backdrop, and sometimes the stage surface itself. To the lighting designer, and automated lighting programmer, they're just another "fixture." Also, with the advent of "digital luminaires" such as the DL.3, DML-1200, and others, we now have moving video projectors, and are no longer limited to images of stencils of stainless steel (gobos).
