Embodiment Construction

[0024] Such as figure 1 As shown, a method for realizing continuous animation effects in a mobile terminal includes:

[0025] Step 1: Divide the initial image into a background part and a transformation part superimposed on the background part, define a corresponding texture image for the transformation part, define the transformation part as a polygon, and record each vertex of the polygon at coordinates in the original image and local space coordinates in said texture image;

[0026] Step 2: Calculate the new coordinates of each vertex of the transformed polygon in the initial image according to the predetermined angle to be rotated by the transformed part;

[0027] Step 3: Divide the polygon obtained in step 2 into multiple triangles, and for each triangle, calculate the coordinates of each pixel on each scanning line constituting the triangle in the initial image and the corresponding local space according to the triangle rasterization principle coordinates, and then cor...

Abstract

The invention relates to a continuous animation effect realization method and a device for a mobile terminal; the method includes that: an initial image is divided into a background part and a conversion part, a texture image is defined for the conversion part, the conversion part is defined to a polygon, the coordinates and local spatial coordinates of each vertex in the initial image are recorded; the new coordinates of each vertex in the initial image after conversion are calculated according to the preset angle; the polygon is divided into a plurality of triangles, and for each triangle, the coordinates and local spatial coordinates of each pixel point of each scanning line which constructs the triangle are figured out, and then the pixel point information of the local spatial coordinates of the texture image are correspondingly filled in the pixel points of the coordinates of the background part; the steps are repeatedly and sequentially executed according to preset time intervalto realize continuous animation effect. The invention can continuously draw the conversion part in the initial image to realize the continuous animation effect.

Description

technical field [0001] The invention relates to the field of mobile terminal applications, in particular to a method and device for realizing continuous animation effects in a mobile terminal. Background technique [0002] At present, with the continuous development of mobile communication technology, mobile terminals have penetrated into people's lives, and mobile communication has become the most widely used communication method. Here, the mobile terminal referred to in the present invention refers to a mobile phone, a personal digital assistant (PDA, Personal Digital Assistant) and other small hand-held mobile communication devices with wireless communication functions. [0003] Taking mobile phones as an example, at present, in the production process of mobile game animations or desktop animations, if drawing continuously rotating pictures or continuous animations of expansion and contraction, developers often use continuous playback of several frames of pictures to achi...
