Abstract
An image rendering method includes acquiring a water wave map corresponding to a target water body region, and acquiring a normal map corresponding to the target water body region in a next image frame based on the water wave map corresponding to the target water body region in the current image frame. The method further includes rendering a water wave effect on the target water body region in the next image frame based on the normal map. The method further includes performing attenuation processing on the water wave map corresponding to the target water body region where the dynamic object is located in the current image frame based on a water wave diffusion attenuation matrix corresponding to the dynamic object to obtain an attenuated water wave map when the dynamic object moves in water.
