Patent ID: 11861788
Assignee: APPLE INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 11:
12. A device, comprising:
a memory storing program instructions; and
one or more processors, wherein the one or more processors are configured to execute the program instructions to:
receive a bit stream comprising:
encoded information for objects of a three-dimensional scene, the encoded information comprising video-encoded two-dimensional image frames comprising immersive video content for the objects of the three-dimensional scene; and
metadata for the three-dimensional scene, the metadata indicating:
areas of the three-dimensional scene; and
respective mesh vertices budgets for respective ones of the areas of the three-dimensional scene, wherein the mesh vertices budgets represent a number of vertices to be used to render objects within the respective areas or a down-scaling factor to be applied to reduce a number of vertices used to render objects within the respective areas;

apply the mesh vertices budgets to the objects included in the respective areas to reduce respective numbers of vertices to be used to render the objects included in the respective areas; and
reconstruct the objects of the three-dimensional scene using the reduced respective numbers of vertices to render the objects as indicated in the metadata.
