  In this paper alternative method for real-time 3D model rasterization is
given. Surfaces are drawn in perspective-map space which acts as a virtual
camera lens. It can render single-pass 360{\deg} angle of view (AOV) image of
unlimited shape, view-directions count and unrestrained projection geometry
(e.g. direct lens distortion, projection mapping, curvilinear perspective),
natively aliasing-free. In conjunction to perspective vector map, visual-sphere
perspective model is proposed. A model capable of combining pictures from
sources previously incompatible, like fish-eye camera and wide-angle lens
picture. More so, method is proposed for measurement and simulation of a real
optical system variable no-parallax point (NPP). This study also explores
philosophical and historical aspects of picture perception and presents a guide
for perspective design.
