Detailed Description

A solid torus of points, useful, e.g., when measuring data from an accretion disc.

The torus's cross section (e.g., a cut at \(\phi=0\)) is a wedge-like shape bounded by \(r_{\text{min}} \le r \le r_{\text{max}}\) and \(\theta_{\text{min}} \le \theta \le \theta_{\text{max}}\).

The grid points are located on surfaces of constant \(r\), \(\theta\), and \(\phi\). There are NumberRadialPoints points in the radial direction between MinRadius and MaxRadius (including these endpoints); NumberThetaPoints points in the \(\theta\) direction between MinTheta and MaxTheta (including these endpoints); NumberPhiPoints points in the \(\phi\) direction (with one point always at \(\phi=0\)).

By default, the points follow a Legendre Gauss-Lobatto distribution in the \(r\) and \(\theta\) directions, and a uniform distribution in the \(\phi\) direction. The distribution in the \(r\) (and/or \(\theta\)) direction can be made uniform using the UniformRadialGrid (and/or UniformThetaGrid) option.

The target_points form a 3D mesh ordered with \(r\) varying fastest, then \(\theta\), and finally \(\phi\) varying slowest.

Note
Input coordinates (radii, angles) are interpreted in the Frame::Inertial
