3D image rendering apparatus and method

摘要

A CPU (201) updates scene data (206) by changing the management order of the data of virtual objects in the scene data (206) based on the processing result of a search of the scene data (206), which is executed upon generating an image of virtual space viewed from a first viewpoint. The CPU (201) sets the updated scene data (206) as scene data (206) to be used to generate an image viewed from a second viewpoint different from the first viewpoint.
