Original Abstract Submitted
Systems, devices, and methods for fixed point implementation of a subdivision processing for video decoding are provided, which may include obtaining two vertices associated with an encoded mesh, determining a first normal vector and a second normal vector with integer components. It may also include determining a first normalized normal vector based on the first normal vector and a second normalized normal vector based on the second normal vector using an inverse square root function and determining a middle normalized normal vector associated with a middle-point based on the combination of the fix-point number with the first pre-defined number of digits, the right-shift operation by the second pre-defined number, and the components of the middle-point. It may also include decoding the encoded mesh based on the first normalized normal vector, the second normalized normal vector, and the middle normalized normal vector.
