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.
