Of the top of my head, I noticed you have written {x.y.z}, you would not use 
periods there, commas are necessary:  {x,y,z}.  Also if you have a large 
set, set them equal to something and enclose the entire set in curly 
brackets.  Then try plotting that something.  Like this:

dataset = { {x1,y1,z1},{x2,y2,z2},{x3,y3,z3}};
ListSurfacePlot3D[dataset,{xrange},{yrange},{zrange}]

Hopefully that helps.
