Light information calculation method and device, storage medium and computer device

Abstract

The application discloses a kind of illumination information calculation method and device, storage medium, computer equipment, the method includes: determining target time and target illumination area in target virtual scene;Judge whether the type of target illumination area and / or the time period of target time belongs meets preset condition;If it meets preset condition, then preset scene light map is sampled to obtain the scene light illumination information of target illumination area;The sky light spherical harmonic coefficient corresponding to target time is calculated, and the sky light illumination information of target illumination area is determined based on sky light spherical harmonic coefficient and shadow mask map;According to scene light illumination information and sky light illumination information, the illumination information of target illumination area is determined.The application can obtain the illumination information that shows 24 hours day and night alternation dynamic change effect in virtual scene, help to improve the realism of illumination effect in game picture, and the performance requirement of low to game device is small.
