XYZ Point data can be interpolated to surfaces (2D grids) and XYZVal data can be interpolated to 3D Grids. To produce a surface with 2D interpolation X, Y, and elevation is required for each data point. To produce a 3D grid with 3D interpolation X, Y, elevation, and a value is required for each data point.
Interpolation is performed on coordinates and values retrieved directly from objects. To interpolate an object that supports interpolation right-click the object node in the Object Manager and select Interpolate… from the context menu to show the Interpolation dialog. The interpolate menu item is only enabled for objects that supports interpolation.
The result of the interpolation depends on both the input data and the configuration of the interpolation algorithm.
