ABSTRACT:
A method of transmitting pictorial data provides for reduction of required transmission bandwidth by constructing the pictorial data in the form of a composite image of primitive pictures. Each of the primitive pictures has a simple geometric form such as a line, a circle, a triangle, and a quadrilateral. Each of these primitive pictures is identified by a parameter, which may take the form of an alphanumeric character. Coordinates of a center of a circle, and of end points of a line, and of vertices of a polygon are identified by pairs of parameters giving the X and the Y coordinates of a two-dimensional display of the image. If desired, the image can be constructed as a perspective view of a three-dimensional object, in which case tetrahedrons, spheres, and hexahedrons may be employed. The parameters are converted to digital signals which are transmitted via a communication link to a display for the regeneration of the original image. The image is generated by decoding the digital signal to obtain the set of parameters, and then constructing the image from the set of parameters.
