A TIN based interpolator calculates grid cell values.
Cell Size
Define the width and height of a grid cell in distance units. Since Grid cells are square both width and height are specified with one value. When you change the cell size, the Grid Dimensions static text control updates to reflect the new dimensions.
Tolerance
Specify a tolerance to control discarding of closely spaced points. This tolerance is specified as a fraction of the diagonal length of the bounding box of the points.
Distance
Specify the distance value to control output of this filter. For a non-zero value, only edges or triangles contained within a sphere centered at mesh vertices will be output. This is useful to constraint the TIN to a specified distance, otherwise the triangulation will cross concave regions.
Feature Angle
Specify the angle (in degrees) that defines a sharp edge. If the difference in angle across neighboring polygons is greater than this value, the shared edge is considered sharp. This is useful to smooth out the final grid.
