20 Claims

1. An image rendering method, performed by a terminal, the method comprising:

obtaining a first shadow map and a second shadow map of a target virtual object, a resolution of the first shadow map being less than a resolution of the second shadow map;

determining a first texel range of each texel and a central point in the first shadow map, the first texel range being set based on a transition distance of a shadow edge and the transition distance being used for indicating a shadow edge of the target virtual object in the first shadow map;

performing, based on the central point, scaling processing on the first texel range by using a scaling coefficient to obtain a second texel range, the scaling coefficient being obtained based on a ratio of the resolution of the first shadow map to the resolution of the second shadow map; and

performing shadow rendering on the target virtual object according to the second texel range.
