Lighting Management in Virtual Worlds

摘要

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.

1. A method comprising:
providing a three-dimensional virtual environment by executing coded instructions on a processor of a game server, and displaying the virtual environment in two dimensions on a display screen of a first computerized appliance coupled to the server; defining a three-dimensional matrix of cells of common dimension within space of the virtual environment having objects with surfaces defined geometrically and positioned by coordinates within the volumetric space of the virtual environment; determining relative occupancy values for cells by volumetric intersection of individual objects with individual cells; determining, cell to cell through the matrix of cells, in the direction of one or more light sources established in the virtual environment, relative illumination values for the cells with consideration of intensity and direction of the light sources and determined relative occupancy values for the cells, including in the determination of illumination values occlusion effects from cell to cell; and displaying illumination effects on surfaces of objects in the two-dimensional display by managing pixel colors and intensity according to illumination values of one or more cells immediately adjacent points associated with the surface.
