### Filter Type list

The Filter Type list allows you to select from the following filter types:

- GAUSSIAN

- SPLINE

- UNIFORM

- TRIANGLE

- CYLINDRICAL.

If you select GAUSSIAN, UNIFORM, or TRIANGLE then the workplane is critical. For these three filter types, the following applies:

If you select the Linear option, the filtering occurs normal (i.e., perpendicular) to the workplane.

If you select Polar option then the filtering occurs in a radial direction within the workplane.
