PURPOSE:To improve operability when local picture editing is executed by reflecting a result obtained by means of executing a density alteration processing for internal voxel data on one's line of view in a picture displayed on a two-dimensional display. CONSTITUTION:A system consists of an input/output device (I/O device) 301, a memory 302, CPU 303, VRAM 304, CRT 305 and a mouse 306. In such a case, one point is instructed by the mouse 306 on the picture which is displayed on the two-dimensional display 305 and which is three-dimensionally and perspectively transformed. The result obtained by giving the density alteration processing to internal voxel data on one's line of view adjusted to a local area including the instructed point is reflected on the picture displayed on the two-dimensional display 305 in CPU 303. Thus, operability in local picture editing can be improved. |
