# Proposals

Proposal 1: Acknowledge 3D Gaussian Splatting as a viable rendering primitive for avatar communication.

Proposal 2: Coordinate with MPEG on the integration of Gaussian splatting data within the ARF Base Avatar Format (ISO/IEC 23090-39).

Proposal 3: Evaluate compression techniques (SPZ, L-GSC, HAC++, Compact3D) for inclusion in the study of static and animation data compression (Objective 7).

Proposal 4: Define capability signaling and conformance points for 3DGS avatar rendering, including supported Gaussian count budgets, supported attribute sets, and required numerical tolerances for determinism.

Proposal 5: Study whether hybrid approaches with small MLPs warrant an optional ARF profile, and if so constrain operator sets and model sizes to preserve portability.
