Parallel Processing on a Transputer-based Graphics Board

One of these tasks is a process called "transformer" that transforms the Objects defined in Real World coordinates into viewing coordinates (Image Space) according to the viewing position and direction. Objects are represented by planar and convex polygons. In this way the viewing transformation of objects is reduced to the transformation of points, namely the vertices of the polygons. The transformer process will perform (4 X 4)-vector­ matrix multiplication using homogeneous coordinates, clipping and, then, perspective transformation to obtain the illusion of depth.
