 """Least squares interpolation.
 
-   Implements a least-squares interpolation.
-   Putting mesh data onto points.
+   These functions and classes calculate a value at a particular point on
+   the given mesh. It interpolates the values stored at the vertices of the
+   mesh.
+   
+   For example, if you want to get the height of a terrain mesh at particular
+   point, you pass the point to an Interpolate class. The point will intersect
+   one of the triangles on the mesh, and the interpolated height will be an
+   intermediate value between the three vertices of that triangle.
+   This value is returned by the class.
