[0031] Please refer to figure 1 , which shows a schematic flowchart of the method for realizing the page-turning effect of an electronic document provided by the first embodiment of the present invention. The method for realizing the page-turning effect of the electronic document in this embodiment is mainly used to realize the page-turning effect of the electronic document in the dragging page-turning operation. The dragging page turning operation refers to an operation mode in which the user interacts with the user terminal through an operation gesture of continuous contact with the touch surface of the user terminal to realize page turning, and the user's operation gesture has a certain sliding track.

[0032] Please refer to figure 1 , in this embodiment, the method for realizing the page-turning effect of the electronic document includes:

Abstract

The invention discloses a method and a device for realizing the page-turning effect of an electronic document. The method includes: determining the page boundary of the electronic document, detecting the initial page turning point and the current page turning point, determining the hem of the page according to the initial page turning point and the current page turning point; The coordinates of the page point and the current page-turning point calculate the current page-turning angle and the current page-turning length; construct a cylinder model and another plane tangent to the cylinder model, so that the cylinder model and the page The tangent line coincides with the folded edge, paste the page texture corresponding to the third area on the cylinder model or the other plane; and detect the next page turning point, and use the next page turning point as the current turning point The page point redetermines the hem of the page and repeatedly executes the step of calculating the movement of the page turning point and the calculation of the cylinder curling until the page turning point disappears. The implementation process of the page-turning effect of the electronic document proposed by the invention is simpler, easier to adjust, and stronger in scalability.

Description

technical field [0001] The invention relates to the technical field of graphics processing, in particular to a method and device for realizing the page-turning effect of an electronic document. Background technique [0002] In recent years, with the rapid development of terminal products such as smart phones, tablet computers, and e-book readers, users have higher and higher requirements for terminal application products. Terminal application products usually interact with users through user interfaces. The page-turning operation for electronic documents is also one of the more common interactions, which often appears in various list interfaces and text interfaces. Page-turning technology has also become a key technology in terminal application products. [0003] Existing page-turning technologies include flash page-turning technology, leaves page-turning technology, ConeCurl cone page-turning technology, etc. Among them, the flash page turning technology has been formed f...
