Method, apparatus, storage medium, program, and program product for generating image data of virtual space

摘要

A method for generating realistic image data of particle system objects locations of which change as time passes, in a light operation load and a little storage capacity. The method for generating image data of a virtual space viewed from a predetermined view point, comprises: providing a particle system object group comprising at least one particle system object in the virtual space, according to a predetermined rule, continuously or intermittently; determining a displacement point in the virtual space; moving the displacement point in a predetermined direction as time passes; and moving the particle system object group on the basis of the displacement point.
