Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0033] An embodiment of the present invention provides a performance-optimized method for picture scrolling shift playback. The so-called "roller displacement" is similar to the rotation of a wheel. Each stripe on the wheel is equivalent to a picture, and every time a stripe touches the ground, it is equivalent to playing a picture. Shift playback forward or backward. Think of the picture as a striped road distributed on the surface of the wheel, which is equivalent to an ordered circular queue, so arrays can be used to organize the data structure. If there are few pictures, the wheel is small, and the length of the array is small; if there are many pictures, the wheel is large, and the length of the array is large. In this way, when the wheel turns, the texture in contact with the ground is equivalent to...

Abstract

The invention discloses a method of roller-type picture displacement playing. The method comprises: analyzing rolling animation, extracting a rolling model, and separating rolling main-bodies and rolling contents; setting the number of containers according to demand, wherein the containers participate in a rolling animation effect, and the picture contents in the containers are updated according to corresponding timing; for the rolling contents, forming an ordered array according to a playing order; and whenever a unit grid is rolled, specifically, firstly moving all the containers as a whole,and then updating a location and updating the contents for the container moved out of a boundary. According to the method, the problem of how to carry out playing on the premise of any number of pictures is solved, repeated rendering is reduced, and performance of rolling-displacement-type playing is maximized.

Description

technical field [0001] The present invention relates to the technical field of picture playing algorithms, for example, similar effects are widely practiced in network rich media applications and game applications, and in particular relates to a method for picture scrolling shifting and playing. Background technique [0002] In general large and medium-sized RPG games, the map and scene resources are generally large. It is almost impossible to render the whole screen, and most of them use the "Carmack scroll" algorithm. The main idea of ​​the "Carmack Scroll" algorithm is to use buffers to update only the changed parts of the rendered map scene, reducing repeated rendering as much as possible to save performance. Drawing on this idea, it can be applied to the scroll wheel shift playback system of pictures. For example, there are 10 pictures arranged in sequence horizontally, and they need to be moved in from the right end of the screen and moved out from the left end to co...
