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.

Abstract: A system has a server with a processor, a storage medium and coded instructions executable on the processor causing the server to display a video game to a player operating a computer, the video game comprising a virtual world having objects with surfaces, movable in the space of the virtual world by the player, and one or more light sources, create and manage a voxel grid associated with the player, compute an occupancy value for individual ones of the cells of the grid, compute an illumination value for cells of the grid by consideration of position and direction of the light sources, the occupancy value of the cell, and illumination values of immediately adjacent cells in the voxel grid, and determine brightness for pixels in display of surfaces of objects in frames of the video game based on the illumination values of cells proximate to the surfaces of the objects.
