Hi, In one attempt MaxPlotPoints did not help, but I was not persistent because I have to resolve other issues before I return to ListPlot3D. One issue is that I cannot pack data. On the big data set I verify that it is numeric array and still I cannot get it packed. Here is an example: mydata={{0.00100,10.,0.},{0.00100,10.,0.00100},{0.00100,10.,0.00200},{0.00100,10.,0.00300},{0.00100,10.,0.00400}}; MatrixQ[mydata,NumericQ] True myPackedData=ToPackedArray[mydata,Real]; MatrixQ[myPackedData, NumericQ] True PackedArrayQ[myPackedData] False What I am doing wrong?
