PURPOSE: To provide the three-dimensional image processing system with which a light source coordinate position or a viewpoint coordinate position matched with desired conditions can be easily set. CONSTITUTION: A two-dimensional perspective image is displayed on a CRT display device, and a desired light source or viewpoint coordinate is inputted as two-dimensional designated coordinate data P by an input device. Three- dimensional central coordinate data F showing the central coordinate position of a plane closest to the position shown by the two-dimensional designated coordinate data P are provided by a first calculation part 14 and based on the three-dimensional central coordinate data F and viewpoint coordinate data G, depth data H showing the depth of the central coordinate position are calculated by a second calculation part 15. While considering these calculated results, light source coordinate data I showing a three-dimensional coordinate position corresponding to the desired light source coordinate or viewpoint coordinate position are calculated at a third calculation part 16. Thus, the position of a light source or a viewpoint can be easily set at about an objective position on a three-dimensional space by anyone. |
