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 $\varphi =0$) 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 $\varphi$. 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 $\varphi$ direction (with one point always at $\varphi =0$).

By default, the points follow a Legendre Gauss-Lobatto distribution in the $r$ and $\theta$ directions, and a uniform distribution in the $\varphi$ 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 $\varphi$ varying slowest.

Note

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