Real-time display of computer generated half-tone perspective pictures

This papper deals with the problem of attaining real-time generation and display of half-tone perspective pictures. The FORTRAN IV program which produces the picture generation simplifies the input require of the user to obtain a given view of an object. Freedom in specifying both the orientation of the object and view point allows complete control over the perspective. The hidden line algorithm utilizes the order in which triangles enter from one scan line to the next and greatly reduce s the amount of scan line computations. With this algorithm, real-time picture generation becomes more of a possibility and real-time display a near-future reality.
