Abstract
This invention relates to a method for generating images by using a ray-tracing method. The method for generating images according to the invention registers only a cell containing the surface of an object among cells that are obtained by dividing the region containing the object to be displayed. The calculation of intersection points is performed only for rectangular parallelepipeds in which the surface exists. Thus it is possible to reduce the time required for displaying the object.
