Abstract:
1. A method for generating a dynamic wallpaper, comprising: initializing a basic visual effect control parameter, wherein the basic visual effect control parameter comprises: an initial depth area, a particle attribute, and a disappearing depth area, wherein the particle attribute comprises: a particle size, a particle emission rate, a particle emission amount, a particle motion direction, a particle location update time, a particle life cycle, and a particle appearance attribute; setting a 3D transformation parameter, wherein the 3D transformation parameter comprises: a model transformation parameter, a view transformation parameter, a projection transformation parameter, and a viewport transformation parameter; rendering a background and particles based on the 3D transformation parameter and the basic visual effect control parameter to generate a dynamic wallpaper; upon detection of a user's touch action on a screen, updating the 3D transformation parameter and the basic visual effect control parameter based on a touch mode and a touch position; and re-rendering the background and the particles in the dynamic wallpaper based on the updated 3D transformation parameter and basic visual effect control parameter; wherein the rendering a background and particles based on the 3D transformation parameter and the basic visual effect control parameter comprises:
