Patent DE-4134576-A1 (DE)
Inventor: COBERNUSS MARTIN DIPL ING
IPC: G06T15/40
Filed: 1991-10-17
Abstract: In raster graphics systems, a Z-memory is used and each Z-coordinate value is compared in a comparator (29) in order to suppress concealed picture elements. The disadvantage of this system is that the whole Z-memory (17) must be initialized or erased in order to ensure that only the valid Z-values of the actual image are compared. The required initialization phases take much time, reduce the available time for building the image and are especially disturbing in image sequences. In order to increase the image exchange speed, the Z-values entered in the Z-memory (17) are permanently allocated to the corresponding image by an image counter (23) and an image number memory (24). The Z-values are then only compared when the Z-values read out from the Z-memory (17) belong to the actual image. Otherwise, the generated Z-values are immediately entered in the Z-memory (17) and the corresponding picture elements are represented. According to the number of distinct images, the Z-memory (17) must be re-initialized or erased only when the available image number band width is exceeded.
