Distortion effect generation method, apparatus and device, and storage medium

The embodiment of the invention provides a distortion effect generation method, apparatus and device, and a storage medium. The method comprises the steps: obtaining an image texture; carrying out distortion processing on texture coordinates corresponding to the image texture to obtain first distortion texture coordinates, wherein distortion processing sequentially comprises water ripple distortion, annular ripple distortion and spiral distortion; obtaining a second distorted texture coordinate input by the user, and superposing the first distorted texture coordinate and the second distorted texture coordinate to obtain a final sampling coordinate; sampling the image texture through the final sampling coordinates, and outputting a sampling result to a temporary texture cache; performing radial distortion processing on the sampling result in the temporary texture cache to obtain a mixed and distorted image texture, and displaying the mixed and distorted image texture in a screen. According to the method disclosed in the invention, a plurality of distortion algorithms can be freely combined, and more abundant and vivid distortion effects such as image rotation and fluctuation can berealized.
