1. A picture generating apparatus using ray tracing comprising:

  • three dimensional scene inputting means for inputting from a data base and storing data of objects including shape data, space distribution data and optical attribution data of said objects composing a virtual three dimensional space;

    data registering means for storing in a voxel table data of said objects in individual voxels obtained by dividing said virtual three dimensional space including said objects into a plurality of voxels;

    picture generating means for generating pictures by applying a ray tracing method to the data of said divided voxels in said voxel table and for displaying the generated pictures using a display device; and

    division number deciding means for determining the number of voxels into which said three dimensional space circumscribing said objects is to be equally divided on the basis of a representative size for a size distribution of all of said objects composing said virtual three dimensional space.
