feature control frame
The tolerance that applies to specific features or patterns of features. Feature
control frames always contain at least a geometric characteristic symbol to
indicate the type of control and a tolerance value to indicate the amount of
acceptable variation.
fence
A multi-segmented line specified to select objects it passes through.
field
A specialized text object set up to display data that may change during the
life cycle of the drawing. When the field is updated, the latest value of the
field is displayed. (FIELD)
fill
A solid color covering an area bounded by lines or curves. (FILL)
filters
See coordinate filters.
final gathering
Final gathering is an optional, additional step to calculating global
illumination. Using a photon map to calculate global illumination can cause
rendering artifacts such as dark corners and low-frequency variations in the
lighting. You can reduce or eliminate these artifacts by turning on final
gathering, which increases the number of rays used to calculate global
illumination.
Final gathering can greatly increase rendering time. It is most useful for scenes
with overall diffuse lighting, less useful for scenes with bright spots of indirect
illumination.
You turn on final gathering on the Advanced Render Settings palette. See also
global illumination.
fit points
Locations that a B-spline must pass through exactly or within a fit tolerance.
See also interpolation points and approximation points.
fit tolerance
The setting for the maximum distance that a B-spline can pass for each of the
fit points that define it.
