Surface Points

On the Implicit tab, in the Surface group, the Surface Points function uses an RBF (Radial Basis Function) to interpolate sparse points on a regular grid. Output can comprise any combination of points, a grid file, and a wireframe.

In most cases you will need to carry out some trial and error processing to determine the optimum settings for the parameters in the Grid Definition tab of the Surface Points form.

Use caution with this function. It is intended for sparse data and should only be used with a small number of input points (< 5000). Including too many points may overwhelm the PC whilst producing a poorer result than would be achieved using fewer points.
