Ok... I think I need some type of soa, yes.
But in the article, there is too much of effort done, to convert 
types to arrays, at least at the stage of my code... At the end, 
if I compare the amount of code in the article and just "[]" 
more, as for the part of my example that works...

Thanks for the cool link, nevertheless... Cool to see, how it 
should be done :)
