Abstract
An image rendering method and a related apparatus, terminal and storage medium that: obtains a low-resolution first shadow map and a high-resolution second shadow map of a target virtual object, determines a first texel range of each texel and a central point in the first shadow map, performs scaling processing, based on the central point, on the first texel range by using a scaling coefficient to obtain a second texel range, and performs shadow rendering on the target virtual object according to the second texel range. A shadow map-based image rendering process is implemented, and since a calculation amount of determining a map position according to a low-resolution map is relatively small, image rendering efficiency is improved. Additionally, rendering of a high-resolution shadow map is completed, generation of edge aliasing is avoided, and an image rendering effect is improved.
