I'm creating some animations on how virus's interact with our evolutionary tree and came across this image of a virus. Basically a sphere with a whole load of evenly spaced random sized sphere's stuck on that don't overlap.
I guess I need to distribute them evenly but with differing densities or clusters.
Has anybody got any suggestions for a direction to take with this ?
All recommendations welcome.

There are some ideas in here http://forums.odforce.net/topic/19771-tesselating-spheres/ [forums.odforce.net]

Hi there eetu
thanks for the link , I'm investigating your projects now and trying to adapt your methods to a sphere.
Just from playing a little - your method is to distribute using the voronoi fracture and scatter sops , then measure the area of the polygons and place a circle at the centre of each poly scaled on the area ?
thanks
John

Eetu that is excellent!
I've had a look at the scene and it's a very elegant idea , using the way the geometry meshes to get a pleasing pattern .
I've been having fun with the voronio noise to get some patterns but am finding the scatter sop a bit limited to create the points based on the noise.
I think it needs a more uniform scatter based on the noise
here's my efforts

BTW my hip file uses the csUniformScatter.otl

Maybe you can get some ideas from that:

Its ICE and I don't know if it is in any way transferable to Houdini, but it may be an inspiration.

thanks for the tip mr bigtree
That looks like just what's needed , it seems the technique is called ‘dart throwing’
searching under those terms I've discovered an old conversation about the same subject were someone's attempted some Vex code to do this
