Block-based partitioning is one of the fundamental techniques in video coding. Geometric-based block partitioning is a well-studied method to enable better spatial adaptation to the signal properties. This paper introduces the most recent proposal of advanced geometric-based inter prediction (GIP) made to the state-of-the-art are video coding standard - Versatile Video Coding (VVC). Implemented in the latest test model VTM-6.0 to generalize the existing triangle partition mode (TPM) and evaluated with the Joint Video Experts Team (JVET) Common Test Conditions (CTC) sequences, the proposed advanced GIP scheme provides luma BD-rate reduction of 0.56% for random access (RA) and 1.37% for low-delay (LB) test cases with 2% encoder runtime increase and negligible decoder runtime increase. Furthermore, BD-rate reductions up to 2.92% and 3.49% for RA and LB test cases can be achieved in the absence of multiple related VVC inter prediction tools.
