Geometric partition mode with increased efficiency

A device for decoding video data, the device comprising:

• a memory configured to store the video data;
• and
• one or more processors implemented in circuitry and coupled to the memory, the one or more processors being configured to:
• determine a first distance index associated with a first geometric partition mode (GEO) angle for a first prediction unit (PU) of the video data to be 4;
• determine, based on the first distance index, a first displacement value indicative of a distance from a center of the first PU to a GEO split such that a location of the GEO split is determined;
• and
• decode the first PU based on the first GEO angle and the first displacement value,
• wherein the first displacement value is half of a displacement value associated with a distance index of 2.

A method of encoding video data, the method comprising:

• determining a first geometric partition mode (GEO) angle for a first prediction unit (PU) of the video data to be 45 degrees;
• based on the first GEO angle being 45 degrees, determining a first distance index for the first PU to be 4;
• determining a first displacement value indicative of a distance from a center of the first PU to a GEO split, the first displacement value being associated with the first distance index;
• and
• encoding the first PU based on the first GEO angle and the first displacement value,
• wherein the first displacement value is half of a displacement value associated with a distance index of 2.
