Abstract
A method includes providing a three-dimensional virtual environment by executing instructions and displaying the environment in two dimensions on a display screen of a computerized appliance, defining a matrix of cells within space of the virtual environment having objects with surfaces positioned by coordinates virtual environment, determining relative occupancy values for cells intersection of objects with cells, determining in the direction of light sources, relative illumination values for the cells with consideration of intensity and direction and occupancy values, including occlusion effects from cell to cell, and displaying illumination effects on surfaces of objects by managing pixel colors and intensity according to illumination values of adjacent cells.
