polar_to_cartesian: Polar to Cartesian Coordinates

In Antguz/rTLS: Tools to Process Point Clouds Derived from Terrestrial Laser Scanning

Description

Convert from polar to cartesian coordinates.

Usage

polar_to_cartesian(polar, threads = 1, digits = NULL)

Arguments

polar	A data.table with three columns describing the zenith, azimuth, and distance of a point to the center.
threads	An integer vector describing the number of threads for parallel processing. Default 1.
digits	A numeric vector of length 1 describing the decimal numbers to round the cartesian coordinates. If NULL, round does not apply. NULL as default.

Value

A data.table with three columns describing the *XYZ* of the cartesian coordinates.
