FFD 1031
Turn on Faceted to provide a faceted look to your
geometry without having to explicitly change the
smoothing groups in the object w ith the Edit Mesh
modifier.
Both
Standard (page 2–1309) and Rayt race (p age
2–1353)
materials provide a Faceted togg le.
Note: This feature was known as “constant
shading” in versions of 3ds Max prior to v5.
FFD
FFD stands for free-form deformation .Itisused
in computer animation fo r effects like dancing cars
and gas tanks. You can use it as well for modeling
rounded shapes such as chairs and sculpture.
An
FFD modifier (page 1–674) surrounds the
selected geometry with a lattice box or cylinder.
By adjusting the con trol points of the lattice, you
deform the enclosed geometry.
Note: Yo u c a n u s e Physique (page 2–927) to control
an FFD space warp. Physique actual ly deforms the
space warp’s control points, which in turn deform
the model.
FGM File
An FGM file (. fgm )isafinalgathermapfile.Itis
used by the
mental ray renderer (page 3–77) to save
the results of a final gathering pass. Generating
and saving an FGM file can speed up subsequent
renderings.
Fi eld o f Vi ew
Above: Narrow field of view
Below: Wide field of view
Field of View defines the width of your view as an
angle with its apex at your viewpoint and the ends
at the sides of the view. The effect of changing FOV
is similar to changing the lens on a camera. As the
FOV gets larger you see more of your scene and
the perspective b ecomes distorted, similar to using
awide-anglelens. AstheFOVgetssmalleryou
see less of your scene and the perspective flattens,
similar to using a telephoto lens.
A Perspective view uses an imaginary camera
with only one setting, FOV. The FOV angle
for the active Perspective view is displayed in
the Rendering Methods panel of the View port
Configuration dialog. You can type a v alue in the
FOV field of the dialog to precisely set FOV for the
active Perspective view.
Use Field of View (FOV) to change the amount of
thescenevisibleandtheamountofperspective
flare applied to a Perspective or Camera view.
The Field of View button appears in the viewport
navigation con trol panel when a Perspective or
Camera view is active.
