Problems solved by technology

Frame animation needs to be produced frame by frame, the file size is large, and because each frame of frame animation is predetermined, it has great limitations and cannot achieve the effect of Aladdin's magic lamp in any direction

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0024] see figure 1 , a method for implementing image special effects based on OpenGL ES, comprising the steps of:

[0025] 1) Obtain the image of the special effect to be realized.

[0026] 2) Obtain special effect execution time length, image area position, target point coordinates and animation direction; the special effect execution time length, image area position, target point coordinates and animation direction can be automatically set by the program or manually set by the user, such as target point coordinates , which can be set by the user by clicking on the touch screen of the embedded device or mobile device; when the animation direction is moving toward the target point, that is, when the contraction effect is realized, the position of the image area is the position of the image to be effected; when the animation direction is the background When movi...

Abstract

The invention relates to the technical field of processing of images of embedded equipment or mobile equipment, and in particular discloses an image special effect realization method based on OpenGL for embedded systems (OpenGL ES). An Aladdin lamp effect on any target point of an image can be achieved. The method comprises the following steps of: 1) acquiring the image to achieve a special effect; 2) acquiring a special effect execution time length, an image region position, coordinates of a target point and a cartoon direction; 3) partitioning a plurality of peaks on the image to achieve the special effect, and calling the OpenGL ES to model the peaks; 4) acquiring the sequence, the speed and the direction of motion of each peak according to the special effect execution time length, the image region position, the coordinates of the target point and the cartoon direction; and 5) moving each peak according to the sequence, the speed and the direction which are acquired in the step 4), and rendering the model by calling the OpenGL ES, so that the image gradually flies away from the target point, and is enlarged and formed, or the image is contracted towards the target point.

Description

technical field [0001] The invention relates to the technical field of image processing of embedded devices or mobile devices, in particular to an image special effect method for realizing the effect of Aladdin's magic lamp. Background technique [0002] The effect of Aladdin's magic lamp means that the image gradually flies out from a target point, zooms in and takes shape, or the image moves towards a target point and then shrinks at the target point, similar to the myth that the god servant flies from the mouth of Aladdin's magic lamp The animation effect of pulling out or retracting. [0003] In the prior art, animation effects are usually realized by frame animation produced by software such as 3DsMax. Frame animation refers to decomposing animation actions, that is, different content is drawn frame by frame on each frame of the time axis, so that it can be played continuously to form an animation. . Frame animation needs to be produced frame by frame, the file size i...
