  • Ray casting method using hardware
    Patent number: 6191789
    Abstract: Ray casting method is performed using a hardware. Ray casting is performed on a 3D object formed in a three-dimensional array of voxels, luminance information is generated for each unit ray path based on voxel information assigned to the voxels on the ray path, and an image related to the 3D object are generated based on the luminance information. At this time, pattern information representing a pattern of the ray paths is previously stored in a branch point table memory. A memory control section determines ray paths for generating the luminance information based on the pattern information.
