#### Calculation Methods

Two methods for calculating the laser surface point are available:

- Planar

- Spherical

Planar Method

This method calculates the laser surface point by fitting a local plane on the scan points within the circular area defined by the horizontal and vertical clipping parameters; this is the default method. Following is an example and its details:

Spherical Method

This method calculates the laser surface point by fitting a local sphere on the scan points within the circular area defined by the horizontal and vertical clipping parameters. Following is an example and its details:

Changing the Calculation Method

To change the calculation method, modify the SurfacePointType registry entry located in the AutoFeatures section of the PC-DMIS Settings Editor. For information on this entry, launch your PC-DMIS Settings Editor and press F1 to access its help file. See the PC-DMIS Settings Editor documentation for more information.
