  This short contribution presents a method for generating $N$-point spherical
configurations with low mesh ratios. The method extends Caspar-Klug icosahedral
point-grids to non-icosahedral nets through the use of planar barycentric
coordinates, which are subsequently interpreted as spherical area coordinates
for spherical point sets. The proposed procedure may be applied iteratively and
is parameterised by a sequence of integer pairs. For well-chosen input
parameters, the proposed method is able to generate point sets with mesh ratios
that are lower than previously reported for $N<10^6$.
