Click OK to convert the XYZ data into a matrix. Expand the Gridding Settings branch, select Random (Thin Plate Spline) from the Gridding Method and Parameters drop-down list, and set both the Columns and Rows to 30.

Select Worksheet: Convert to Matrix: XYZ Gridding to open the dialog.

Activate the workbook XYZ Random Gaussian again.

And then, use the result Matrix data to create the 3D surface. If you want to create a 3D surface that is smoother than the surface plot above(created from XYZ data), you can firstly convert the XYZ data into a matrix using the XYZ Gridding tool. Drag with your mouse or use arrow keys to change lighting source direction. Press the "S" key while hovering on a 3D openGL graph. In the Lighting tab, select Directional as Mode and do the settings under Light Color just as the image below showing.
