syntax of the commands
Lisp surfaces uses as interpolation formula the "Interpolation between weighted mean three-dimensional points". This method requires the selection of at least three points for the interpolation vertex.
For each vertex of the grid the radius selection finds the points for the interpolation.
If Lisp Surface does not find at least three points for the interpolation of the vertex within the radius selection value then it will utilize the increment value of the radius.
The limit of the increment value of the radius of the selection is a control as to how much (n) increment of the radius may be added for the selection. When the limits of increment are reached then Lisp surface interrupts the interpolation loop and surface creation and reports the failed value into the layer.
The quality of the interpolation of the grid is controlled by the radius of the selection.
The radius selection finds the points to be included in the interpolation of the vertex and all points selected are processed into the interpolation.
If Lisp Surfaces uses a high value for the radius selection also points that are more distant from the vertex will obviously be processed. In this case Lisp Surface returns a value elevation for the vertex that is less reliable.
When Lisp surface does not find, within the selected value of the radius, three points for interpolation it uses the increment value for the radius. Lisp surfaces then also creates a layer report on this specific case. The layer name is "out_radius_x" (x = progressive number).
The information printed for such points is:
If Lisp surfaces does not find at least three points required for the interpolation (in the radius selection value plus the increment value) the loop interpolation and the creation of the surface are interrupted.
In this case, Lisp surface prints the vertex in object into the layer "out_radius_x".
