Usage

This a plugin approximates set of points given by the Input Mesh property.

In order to approximate a specific set of point you must create that set on another object and connect this object Ouput Mesh (probably from the Instance of this object) to the Input Mesh of this plugin.
Also you must add the functions you would like to use in the approximation. To do so, add a new user property clicking on the + button on the properties panel.
Add a String (second dropdown menu) from the Generic Property (first dropdown menu).
You may also add other variables like in the SurfacePlot plugin.

Here is a screenshot of a resulting surface. Of your you may animate it so see how it approximates the points. Beware: In some cases you may generate an unsolvable linear system. Then the surface won't be updated. Check on the Help->Open Log Window... window to see if you had any error.
You will see a message like in the image above (although in this case it doesn't correspond to the displayed surface)
