This application discloses an image rendering method and apparatus, an electronic device, and a storage medium, and belongs to the field of image processing technologies. The method includes: acquiring a lightmap of a target three-dimensional model in response to a light rendering instruction; acquiring a seam edge of the target three-dimensional model; determining, in the lightmap, a target pixel corresponding to the seam edge; and updating an initial pixel value of the target pixel in the lightmap to obtain a repaired lightmap. In this application, the seam edge of the target three-dimensional model is automatically identified, and the pixel value of the target pixel is automatically updated, so that automatic recognition and automatic repair of a seam problem can be completed by one click, thereby avoiding a waste of labor resources for troubleshooting and repairing the seam problem, reducing image rendering time, and improving image rendering efficiency.

Lightmap updating method and apparatus, electronic device, and storage medium

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.
