AI Technical Summary
Technical Problem
The resolution limitations of soft shadow maps generated in existing technologies lead to a loss of detail, resulting in shadow effects that are not refined or realistic enough.
Method used
By increasing the number of vertices in the mesh model of the virtual object, a more refined second mesh model is generated, and a soft shadow map is generated based on this model. The refined mesh model is then used to generate more refined soft shadows during the rendering process.
Benefits of technology
It improves the detail and realism of shadow effects while reducing rendering time and computational requirements, thus increasing rendering efficiency.

Abstract
This application discloses a method, apparatus, device, medium, and product for generating soft shadow maps, belonging to the field of 3D rendering. The method includes: obtaining a first mesh model corresponding to at least one virtual object in a virtual scene; increasing the number of vertices in the first mesh model corresponding to the at least one virtual object to obtain a second mesh model corresponding to the at least one virtual object; and generating a soft shadow map of the first mesh model corresponding to the at least one virtual object based on the second mesh model, wherein the soft shadow map is used to generate soft shadows for the at least one virtual object, and the soft shadow is a shadow with varying shadow parameters in the edge region. This method generates soft shadows based on the refined second mesh model corresponding to at least one virtual object, enabling the generation of more realistic soft shadow effects.
