Table Of Contents
facet The underlying structure of the face of a 3D solid, surface, or mesh.
Facets can be quadrilateral or triangular. Smoothing a mesh object increases
the number of facets for each face.
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 multisegmented 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.
First Contact balloon The interactive graphical tooltip that is displayed when
the SteeringWheel is pinned during startup.
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.
floating panel
A ribbon panel that is not attached to the rest of the ribbon or file window.
floating viewports See layout viewports.
font A character set, made up of letters, numbers, punctuation marks, and
symbols of a distinctive proportion and design.
