[chimera-dev] Icosahedral lattice on a sphere

[Wei Zhang]

Hello,

I use the command hkcage to generate an icosahedral lattice on a sphere:

hkcage 5 7 sphere 1

However, this only expands the strict icosahedral lattice (ie when using
sphere=0) radially to match a spherical surface. As a result, the sizes of
the hexagons and pentagons are not the same. The effect would be very
dramatic if the parameter sphere is larger than 1.

I am wondering if the code can be modified to generate a truly icosahedral
lattice on a spherical surface, or if that piece of code is open to access?

Thank you and best regards,

Wei
