The common architecture of multi-view autostereoscopic displays assigns a nominal viewing distance. The design affects the convergence of the visible rays at a nominal viewing distance where diamond shaped viewing zones are created. In contrast to this approach, the authors present a new design strategy departing from the geometric relations of common 3D display designs. They show that a beam emitted from a sub-pixel should be rendered with an individual camera direction determined by an algorithm. This algorithm also uses, besides the parameters of the display design, the desired viewing distance and the allowed increments of the camera angle. This enables very flexible designs of autostereoscopic displays. The main difference from the common multiview display is that its design approach enables a continued viewing zone without the usually diamond shaped sweet spots. The algorithm for controlling the rendering and the multiplexing is generic, as well as for integral and multiview design approaches using an image splitter raster. The paper introduces it for autostereoscopic displays with horizontal parallax.
