203. forming at least one horizontal ripple simulation line on the turnover picture;
in this embodiment, the horizontal ripple simulation line may be a sine curve, and the specific number thereof, that is, at least one specific numerical value may be set by the size of the view slice; in specific implementation, two adjacent horizontal ripple simulation lines are not staggered in the horizontal direction, and certainly, different horizontal ripple simulation lines are also feasible to be staggered in the horizontal direction; in addition, the at least one horizontal ripple simulation line may not be equidistantly arranged on the reversed picture, and of course, may also be equidistantly distributed on the reversed picture;
204. acquiring a horizontal central line corresponding to the horizontal ripple simulation line;
more specifically, each horizontal ripple simulation line has a corresponding horizontal center line, please refer to fig. 4; the horizontal central line 402 divides the corresponding horizontal ripple analog line 401 into an upper part and a lower part, wherein the upper part is a region where a wave crest is located, and the lower part is a region where a wave trough is located;
