Use ListSurfacePlot3D or TriangularSurfacePlot.

Load the graphics packages.

Unlike ListPlot3D, ListSurfacePlot3D takes a matrix of points.
In[2]:= data = Table[{x, y, x+y}+.5{Random[],Random[],Random[]}, 


ListSurfacePlot will handle some holes but it's a bit picky if it has 
too many. If that's the case, you can use TriangularSurfacePlot.

Load DiscreteMath

TriangularSurfacePlot takes a list of points.
