Document Type and Number:
WIPO Patent Application WO/2021/253642
Kind Code:
A1
Abstract:
An image rendering method and apparatus, a computer program and a readable medium. Said method comprises: determining whether a target object is visible in a first viewport camera (101); if the target object is visible in the first viewport camera, determining the area of a projection region occupied by the target object in a scene viewport (102); if the area is less than a first preset threshold, acquiring a patch map corresponding to the target object (103); and drawing the patch map corresponding to the target object to the scene viewport (104). By replacing vertex data of a model with a patch map, the number of drawn vertexes is reduced, and the rendering efficiency is improved.
