摘要： Disclosed is a three-dimensional radar apparatus comprising a radar transmitting/receiving unit (14), a three-dimensional polygon-generating unit (16), and a three-dimensional graphics unit (18), wherein a radar transmitter/receiver (20) outputs signals concerning orientation information, distance information, and reception intensity information on the basis of a radio wave reflected from a target, and a scan converter (22) is used to convert the signals concerning the orientation information, the distance information, and the reception intensity information into two-dimensional radar image data composed of two-dimensional rectangular coordinates and brightness information of each of picture elements. The two-dimensional radar image data is also inputted into the three-dimensional polygon-generating unit (16) to perform polygon-generating processing on the basis of the two-dimensional rectangular coordinates and the brightness information of each of the picture elements. Three-dimensional radar image data is prepared in the three-dimensional graphics unit (18) on the basis of obtained polygon-based information, and it is accumulated in a frame memory (24). Thus, a three-dimensional radar image is displayed on a display device (26).

摘要： 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 (14). A memory control section (16) determines ray paths for generating the luminance information based on the pattern information.
