The resulting integrals are mapped to the midpoint of each GB's corresponding triangular sphere element and visualized as contours on the sphere mesh surface. By virtue of its construction, a point in 𝒫 maps to a G in 𝜌, any arbitrary path in 𝒫 maps to a zero-flux surface, and any closed path in 𝒫 corresponds to a gradient bundle in 𝜌.
