Geosphere?

Note that the above results in just a fairly nice approximation, though. (And I don't know if it matches the subdivision used in your example image.) Only for the (not really sphere-like, as they have so few faces) Platonic solids are the vertices in a strict sense evenly distributed, though. See http://www.cgafaq.info/wiki/Evenly_distributed_points_on_sphere and especially http://www.math.niu.edu/~rusin/known-math/95/sphere.faq .

Approximation is ok. Just just want to take a fixed number of points and distribute them approximately evenly. Doesn't matter if they need to be rounded to a number that fit some geometric restriction.

Thanks for the links - I'll look into them.

Excellent - the spiral methods works great for my use!

Its pretty common to subdivide a cube and then project onto a sphere.

If you want evenly distributed but not a regular mesh, you could use a Hammersley point set.

Would that give a even-ish distribution?

Thanks for the pointer - will look it up.

A sphere with a center (x0,y0,z0) with diameter r
has all points x,y,z like

with

= Latitude

= longitude

That is just how I would do it!

Me too

Google are really quick to index this site!
I did a search for "Hammersley point set sphere" and this thread came up as #3 already.

Not busy enough elsewhere, eh tml?
Thank you for your talents, also.

There you go.
