Abstract:
A method of simply and artificially displaying, on a display device, a fluid flowing from top to bottom along a three-dimensional surface which has a semispherical configuration, comprising the steps of:mapping a fluid start point defined on top of the three-dimensional surface onto a predetermined flat surface to decide a provisional start point on the predetermined flat surface; determining an initial fluid density at the provisional start point on the predetermined flat point; deciding a succeeding fluid density after lapse of a unit time at each of the provisional start point and adjacent points which are spaced from the provisional start point by a unit distance in a plurality of prescribed directions, so that the succeeding fluid density at each of the provisional start point and the adjacent points is decreased in comparison with the initial fluid density at the provisional start point; successively calculating a next following fluid density at each of the provisional start point and the adjacent points each time when a next unit time lapses, the next following fluid density being obtained by calculating not only a fluid caused to flow into each of the provisional start point and the adjacent points but also a fluid caused to flow returned back from the adjacent points to the provisional start point even when the provisional start point is defined on the top of the three-dimensional surface; re-mapping each of the succeeding and the next following fluid densities of the predetermined flat surface onto the three-dimensional surface as re-mapped results; and successively displaying the re-mapped results on the display device.
