Hi Alastair,
as I understand "nomalizing" it only works with vectors, because only a vector
has a "length".
From the GLSLLangSpec.4.00.8:
"genType normalize (genType x) - Returns a vector in the same direction as x
but with a length of 1."
Is this what you need? I what context do you need this in JS?
best,
