Abstract
This application relates to an illumination rendering method performed by a computer device. The method include: determining light source change information when a light source changes in a virtual scene; determining a current light source projection coefficient corresponding to the changed light source according to the light source change information; determining an indirect illumination value of a target pixel point in the virtual scene according to a radiance transfer parameter corresponding to the target pixel point in the virtual scene and the current light source projection coefficient; determining a direct illumination value corresponding to the target pixel point under the changed light source; and performing illumination rendering on the target pixel point according to the direct illumination value and the indirect illumination value.
