The G3GRID Procedure |
Requirements: | An input data set is required. |
PROC G3GRID
<DATA=input-data-set>
<OUT=output-data-set> <OUTTRI=output-data-set>; |
Options |

Depending on the shape of the original data and the options you use, the output data set may contain values for the vertical (z through z-n) values that are outside of the range of the original values in the data set.
Featured in: | Using the Default Interpolation Method |
The data set contains three observations for each value of the variable TRIANGLE. The three observations give the coordinates of the three vertices of the triangle. Points on the convex hull of the input data set of points are also assumed to lie in degenerate triangles whose other vertices are at infinity. The points in the convex hull can be recovered by keeping only those triangles with exactly two missing vertices.
By default, no OUTTRI= data set is produced. OUTTRI= is not valid when you specify the SPLINE option in the GRID statement.
