A novel fast human vision adapted 3 D visualization engine with an easy main memory access

A novel fast human vision adapted 3D visualization engine is described. In accordance with the human vision peculiarities (asymmetry between left-right and up-down oppositions, dependence of the spatial resolution on the velocity, etc.), we use the cylindrical coordinate system whose axis coincides with the symmetry axis of an observer, and implement the different rendering regimes for moving and immobile observers. Usual Zbuffer ray casting algorithm is modified to best correspond to this coordination system and other aspects of the problem (we name it R-buffer algorithm). WATCOM 11 C/C++ with ASM files language was used to write the 3D engine described, and special attention was paid to ensure the fast and easy main memory access. The engine enables to handle simultaneously a great number of moving objects with different illumination and shadow conditions, as well as to image the changes of the objects (like car wheel tracks on the ground).
