[maxmsp] 2d.wave~ question

Hi,

I've been using Max for a couple of years now but have only recently begun to play around with the 2d.wave~ object. I'm getting some great results with it but I am still a little ignorant as to how it works exactly and I found the help file a little vague. From what I gather, it creates a kind of wave terrain from the file loaded into its buffer~ by slicing(?) it into "rows". But how are these rows arranged "spacially" exactly? How could this be displayed graphically perhaps? I would very appreciative if anybody has, or could point my in the direction of any further info on this object or on wave terrains in general (Ive read Curtis Roads material in the past but do not have immediate access to it at present).

Thanks.
