1. A digital vector generator system comprising: a plurality of spatial vector generators coupled to receive position information representing a visual image and to generate in response thereto data defining a sequence of pixel coordinate points defining a line within a display image; and at least one visual characteristic vector generator coupled to receive visual characteristic information representing the visual image and to operate synchronously with the spatial vector generators to generate in response to the received visual characteristic information visual characteristic vector information corresponding to each pixel coordinate point defined by the data generated by the spatial vector generators; and means for generating a video signal coupled to receive the sequence of pixel coordinate points from each of the spatial vector generators and the visual characteristic vector information from the at least one visual characteristic vector generator and generating a video signal representing the video image in response thereto.
