Surface

On the Implicit tab, in the Surface group:

• the Polygon function uses an RBF (Radial Basis Function) to interpolate data from closed strings or polygons. The input data must comprise closed polygons representing adjacent slices through a 3D shape (such as an orebody interpretation or profiles of underground mine workings). As with the application’s other implicit modelling functions, the output from this process is a wireframe representing the 3D shape.

• Click Point Cloud to create a surface using points resting exactly on an open or solid surface. The output is a wireframe of the surface.

• 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.

• Click Downsample Points to reduce the number of data points in an input dataset whilst retaining the integrity of the data. This is a pre-processing step for dense (e.g. LIDAR) data sets.
