Abstract

We disclose a method to generate (u,v) coordinates at the decoder side using the parameters of the orthogonal projection function transmitted via the atlas bitstream. Using the orthogonal projection parameters, the decoder can efficiently generate the (u,v) coordinates and avoid costly coding.
