Abstract
A picture generating apparatus using ray tracing has means for inputting data of objects from a data base for storing data of objects composing a virtual three dimensional space, means for registering the data of the virtual three dimensional space divided into a plurality of voxels represented by data in a voxel table, means for determining a voxel subdivision number on the basis of representative parameters expressing geometrical information on said objects composing the three dimensional space, such as the object average size, and means for generating pictures by applying a ray tracing method to the divided voxels and displaying the generated pictures.
