x = radius * math.sin(phi_in_radians) * math.cos(theta_in_radians) y = radius * math.sin(phi_in_radians) * math.sin(theta_in_radians) z = radius * math.cos(phi_in ...

Abstract: Common methods for calculating the converted Cartesian position measurement and associated covariance from polar or spherical measurements are: standard conversion, debiased conversion, ...

This extension is capable of unwrapping cylindrical surfaces into flat faces and vice versa. This is achieved by converting the Cartesian coordinates of each vertex into cylindrical coordinates and ...

In this study we explore the interference rejection and spatial sampling properties of multi-axis Optically Pumped Magnetometer (OPM) data. We use both vector spherical harmonics and eigenspectra to ...
