If you are confident that you never have negative radius, you can 
completely do away with the comas.

General rule : Comas are optional in all cases where the separation 
between consecutive values is unambiguous. The only case where it can be 
ambiguous is the case of a negative value that will be interpreted as an 
operation.

1 1 1 is equivalent to 1,1,1
1, -1 1 is OK, but 1 -1 1 will be interpreted as (1-1) 1 or 0 1
