Rendering optimization method, electronic device, and computer-readable storage medium

An electronic device, comprising:

• one or more memories storing one or more programs;
• and
• a processor configured to execute the one or more programs to cause the electronic device to perform operations comprising:
• determining first polygonal mesh data corresponding to an object model in a scene, wherein the first polygonal mesh data is for describing the object model;
• creating a bounding box corresponding to the object model based on the first polygonal mesh data;
• determining a pixel range covered when the bounding box is projected onto a screen of the electronic device, obtaining a relationship between a quantity of pixels covered by the bounding box and a quantity of pixels of the screen, and determining a distance between an observation angle in the scene and the object model;
• determining a level of detail (LOD) level corresponding to the object model based on the distance and the relationship, and updating the first polygonal mesh data to second polygonal mesh data based on the LOD level;
• and
• rendering the object model based on the second polygonal mesh data.

A non-transitory computer-readable storage medium storing a computer program that, when executed by a processor, causes an electronic device to perform operations comprising:

• determining first polygonal mesh data corresponding to an object model in a scene, wherein the first polygonal mesh data is for describing the object model;
• creating a bounding box corresponding to the object model based on the first polygonal mesh data;
• determining a pixel range covered when the bounding box is projected onto a screen of the electronic device, obtaining a relationship between a quantity of pixels covered by the bounding box and a quantity of pixels of the screen, and determining a distance between an observation angle in the scene and the object model;
• determining a level of detail (LOD) level corresponding to the object model based on the distance and the relationship, and updating the first polygonal mesh data to second polygonal mesh data based on the LOD level;
• and
• rendering the object model based on the second polygonal mesh data.
