1. A method of encoding point cloud data, the method comprising:
determining, with one or more processors, an amount by which a laser turns for determining points in a point cloud represented by the point cloud data, wherein determining the amount by which the laser turns comprises one of:
determining a number of laser probes by the laser in one single rotation; or
determining a change in an azimuth angle by which the laser turns;
generating, with the one or more processors, a syntax element indicative of the amount by which the laser turns for determining the points in the point cloud, wherein a value of the syntax element is a defined value less than the amount by which the laser turns, and wherein the defined value is 1; and
signaling, with the one or more processors, the value of the syntax element.
