1. A method of encoding or decoding video data, the method comprising:
determining that geometric partition mode is enabled for a current block of the video data, the geometric partition mode comprising a plurality of split modes that each defines a respective edge for partitioning;
for each split mode, among at least two split modes of the plurality of split modes, determining a respective cost associated with a respective split mode, the respective cost indicative of a likelihood of use of the respective split mode;
constructing, based on the respective costs associated with the respective split modes, a mapping list including index values respectively associated with values indicative of the respective split modes, where a lower index value in the mapping list is associated with a first split mode having a lower cost than a second split mode with a higher index value in the mapping list;
determining a split mode amongst the plurality of split modes within the mapping list; and
reconstructing a current block of the video data based on the split mode.
