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

Claim 5:
6. The non-transitory computer-readable medium of claim 1, wherein the program instructions, when executed on or across the one or more processors, further cause the one or more processors to:
perform a rate distortion optimization analysis to determine a number of areas to identify in the three-dimensional scene, wherein the rate distortion optimization optimizes the number of areas to identify based on:
a data size of the metadata, wherein a larger number of areas results in a larger data size of the metadata and a smaller number of areas results in a smaller data size of the metadata;
grouping at least two objects, or object portions, with different object complexity values into a common area and determining for the common area:
an amount of distortion resulting from applying a first lower mesh vertices budget for rendering the at least two objects;
an amount of rendering overhead resulting from applying one or more higher mesh vertices budgets for rendering the least two objects; and

separating the at least two objects, or object portions, with different object complexity values into at least two separate areas and determining for each of the separate areas:
an amount of distortion reduction resulting from applying different mesh vertices budgets for the at least two objects, or object portions, having different complexity values; and
an amount of rendering overhead reduction resulting from applying different mesh vertices budgets for the at least two objects, or object portions, having different complexity values.
