| In the Algorithm tab the type of interpolation is selected and configured. 2D interpolation algorithms produce surfaces. 3D interpolation algorithms produce 3D Grids.

| First step is to select the point data that should be interpolated. The source object is already selected when the dialog is shown. When the Get Data button is pressed the interpolation dialog is asking the source object for point data. The result of pressing the Get Data button depends on the type of source object. For XYZ Points and Chem5 Water Chemistry the [[:geoscene3d:application:interpolation:interpolation_wizard:select_xyz_point_data|Select XYZ Point Data]] dialog is shown, whereas the [[:geoscene3d:application:interpolation:interpolation_wizard:select_resistivity_xyz_data|Select Resistivity XYZ Data]] dialog is shown for ODV Models. When data has been retrieved from the source object summary information is shown for the data.\\ | First step is to select the point data that should be interpolated.

| __Smooth Factor: __ If smooth factor is larger than zero each data point weight is reduced and the interpolation will produce a smoother grid. Beware that smoothin will result in a grid surface that is not exact, meaning that grid node values might be larger or smaller than the input data point values. If smooth factor is zero the resulting grid will be exact. Grids may also be smoothed in the [[:geoscene3d:application:interpolation:interpolation_wizard:geoscene3d_toolbox|GeoScene3D Toolbox]] \\ | __Smooth Factor: __ If smooth factor is larger than zero each data point weight is reduced and the interpolation will produce a smoother grid.

| When the grid is interpolated (2D and 3D) the grid nodes are interpolated one by one. In the search tab it is specified how far away from the interpolated grid point the algorithm should look for data points. If no data points are within search radius the grid node will be blank in the resulting grid. \\ __Search Ellipsis/Ellipsoid:__ In 2D interpolation X and Y describes the major and minor radius in the search ellipsis. For 3D interpolation X, Y and Z describes the major, minor, and vertical radius in the search ellipsoid. \\ __Search Ellipsis/Ellipsoid Angle:__ Rotation angle of the search ellipsis/ellipsoid. In 2D Angle 1 rotates the search ellipsis clockwise around the vertical Z axis. In 3D Angle 2 rotates the ellipsis around the rotated Y axis ("dip"). In 3D angle 3 rotates the ellipsis around the rotated X axis ("plunge"). \\ See [[:geoscene3d:application:interpolation:interpolation_wizard:kriging|Kriging]]. | When the grid is interpolated (2D and 3D) the grid nodes are interpolated one by one.

| When this tab is visible partial interpolation is possible. Partial interpolation means that even when working in a local scene extent with only a fraction of both source data points and destination grid visible, the entire grid is updated seamlessly. | When this tab is visible partial interpolation is possible.

| __Partial Interpolation:__ Only the portion of the grid that will be modified by the interpolation is updated. Recommended if the grid file is up to data.

| __Full Interpolation:__ The entire destination grid will be interpolated and updated. All source data required to interpolated the entire grid is extracted from source. This may be time consuming in case of large amounts of data, but may be necessary if the destination grid is not up to data, i.e., if you know that data outside the current source data extent has changed. | __Full Interpolation:__ The entire destination grid will be interpolated and updated.
