Abstract

Embodiments of the present invention provide a method and device for determining a shadow map. The method for determining a shadow map includes: acquiring the current video frame of an application scene and the previous video frame of the current video frame; Whether the shadow map of the displayed object is the same as the shadow map of the object displayed in the previous video frame; if they are the same, determine the shadow map of the object displayed in the previous video frame as the current video frame The shadow map of the object to be displayed; if not the same, draw the shadow map of the object to be displayed in the current video frame. Through the technical solutions provided by the embodiments of the present invention, the shadows of objects in the application scene can be made more real, and the user experience of the user in the application scene can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for determining a shadow map. Background technique [0002] In order to improve the user experience of the user in the application scene, the shadow of the object will be displayed in the application scene, wherein the application scene may be: a 3D animation scene, a 3D movie scene, a 3D game scene, and the like. [0003] The following uses a 3D game scene as an example for illustration. During the process of running a 3D game, the terminal will simulate the shadows of objects in the 3D game scene in order to enable users to have a real experience in the game that is closer to the real environment. Wherein, the terminal simulates the shadow of the object in the 3D game scene by drawing a shadow map of the object in the 3D game scene, and determining the drawn shadow map of the object in the 3D game scene as the shadow of the object in the 3D ...
