Three-dimensional simulation page turning method and system

Abstract

The invention relates to the technical field of image processing, and discloses a three-dimensional simulation page turning method and a three-dimensional simulation page turning system. The three-dimensional simulation page turning method comprises the following steps: S1, confirming the page turning direction, the projection position of a central line of a virtual column and the radius of the virtual column according to the gesture input by a user; S2, dividing a screen into three areas, namely a part below the column, a column surface and a part above the column; S3, uniformly dividing the column surface into a plurality of equal parts parallel to the central line of the column, and calculating the cross points of the bisectrixes and the screen boundary; S4, coiling a horizontal picture of a page to be adhered to the column, and calculating three-dimensional coordinates of cross points of page boundary points, bisectrixes of the areas on the surface of column, and the page boundary after the horizontal picture is adhered; S5, scheduling a three-dimensional drawing engine to draw calculated picture data. By adoption of the three-dimensional simulation page turning method and the three-dimensional simulation page turning system, three-dimensional page turning effect can be drawn according to the input of the user in real time, real three-dimensional display is achieved, and meanwhile as the model of the method and the system is simple and easy to use, the resource occupation of a processor is reduced, the reaction speed is fast, and the real-time effect is relatively ideal.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a three-dimensional simulation page turning method and system. Background technique [0002] The miniaturization and portability of electronic devices has changed many habits in people's daily life, and electronic reading is one of the most obvious changes. Using portable electronic devices, people can not only browse the web and read news, but also read e-books, flip through e-magazines, or flip through e-photo albums with the support of various application software. Compared with heavy paper books, e-reading is Enriching people's spiritual life provides great convenience. Although e-reading has the advantages of portable equipment and rich resources, many users said that the e-reading method lacks real texture, and there is no big problem in static reading of single-page content. Problems such as inconvenient page turning and difficult reading and positioning of text...

Problems solved by technology

[0004] 1. Scrolling, that is, within the page area displayed on the screen, multiple pages of content are displayed by moving the content to be displayed up and down or left and right; this method has a small amount of calculation for processing equipment and is easy to implement, but it differs greatly from the actual reading situation, and The position of the page content changes frequently, making it difficult for users to read and locate, and the experience is poor

[0005] 2. Gradient type, that is to use a gradual method to switch the current display content from clear to blurred, and then switch from blurred to clear content to be displayed, thereby completing the switching of page content; this method is also easier to implement and has certain The simulation effect, but because the page is switched as a whole, the switching effect needs a certain display time, and the effect of quickly turning pages or turning pages back and forth is not ideal

[0006] 3. Two-dimensional simulation, that is, divide different filling areas by calculating the curves in the two-dimensional space, and then fill in different shadow effects and graphic effects in each area to simulate and display the page turning effect. The common two-dimensional simulation page turning The effect is as figure 1 As shown; this method is closer to the real page-turning effect, but because it involves real-time calculation and rendering of multiple curves and a large number of points (a relatively simplified typical algorithm is disclosed in Chinese patent document CN101930340A), the calculation amount is relatively large, and the The response speed has a certain influence. In addition, because it is displayed through the combination of curves in two-dimensional space, the actual display effect is still far from the reality, especially the boundary effect is difficult to achieve smooth and natural
