Assignee: APPLE INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A non-transitory computer-readable medium storing program instructions that, when executed using one or more processors, cause the one or more processors to:
obtain mesh geometry information for volumetric visual content, wherein the mesh geometry information comprises vertices information and connectivity information for a geometric representation of the volumetric visual content;
obtain compressed attribute information for the volumetric visual content; and
identify triangles in the geometric representation of the volumetric visual content using the mesh geometry information; and
for respective ones of the identified triangles:
predict an attribute value for a third vertex of a respective triangle based on:
signaled, or previously predicted, attribute values for two other vertices of the respective triangle; and
a geometric correlation between the respective triangle in the geometric representation and a corresponding representation of the respective triangle in the attribute information; and

apply an attribute correction value included in the compressed attribute information to the predicted attribute value to generate a decompressed attribute value for the third vertex of the respective triangle.
