Abstract
In a system for displaying geophysical information on a video screen, data representative of spaced subsurface strata are stored in a computer memory. The data are extracted, plane by plane, and data bytes representative of the planes are stored in pairs in memories in an image processor. The data representative of one plane is displayed and recorded on a medium such as video tape. An image is then formed using a large fraction of the value of the data representative of one plane and a smaller fraction of the data representative of the next plane, and that image is stored. Successive images are formed using decreasing fractional amounts of the data representative of the first plane and increasing fractional amounts of the data in the next plane. Each image is stored and displayed, the display presenting a sequence of images which appear to merge or dissolve smoothly from one to the next. The process is repeated through all stored strata.
