Visual computing is a field of computing that deals with the acquisition, analysis and synthesis of visual data through the use of computer resources. It encompasses several fields of science (computer science, in particular), mathematics, physics and the cognitive sciences. Visual computing aims to let us control and interact with activities through the manipulation of visual images, either as direct objects or, simply, representations of nonvisual objects. The media involved can be images, 3D models, videos, block diagrams and even simple icons.
Visual computing is a rather large field with many subfields, but all are related to the visual aspect of computing. Visual computing deals with everything related to computer visuals - from hardware to mathematical equations behind each pixel of color. Its primary aim is to use visual entities for the manipulation of everything around us, tangible or intangible. Visual computing can be broken down into two main branches, as follows:
