Use Viewpor t settings—
Lets you set different
rendering parameters, and displays the mesh
generated by the Viewport sett ings. Av ailable only
when Enable in Viewport is turned on.
Genera te M appi ng Coords—Turn thi s on to apply
mapping coordinates. Default=off.
The U coordinate wraps once around the thickness
of the spline; the V coordinate is mapped once
along the length of the spline. Tiling is achieved
using the Tiling parameters in the material itself.
Real-World Map Size—Controls the scaling method
used for texture mapped materials that are applied
totheobject. Thescalingvaluesarecontrolled
by the Use Real-World Scale settings found in
the applied material’s Coor dinates rollout (page
2–1625).Default=on.
Viewport—Turn this on to specify Radial or
Rectangular parameters for the shape as it will
display in the v iewport when Enable in Viewport
is turne d on.
R end er er—Turn this on to specif y Radial or
Rectangular parameters for the shape as it will
displaywhenrenderedorviewedintheviewport
when Enable in Viewport is turned on.
Radial—Displays the 3D mesh as a cylindrical
object.
Thick ness—Specifies the diameter of the viewp ort
or rendered spline mesh. Default=1.0. Range=0.0
to 100,000,000.0.
Splines rendered at thickness of 1.0 and 5.0, respectively
Sides—Sets the number of sides (or facets) for
thesplinemeshntheviewportorrenderer.For
example, a va lue of 4 results in a square cross
section.
Angle—Adjusts the rotational position of the
cross-section in the viewport or renderer. For
example, if the spline mesh has a square cross
section you can use Angle to position a "flat" side
down.
Rectangular—Displays the spline’s mesh shape as
rectangular.
Aspect—Sets the aspec t ratio for rectangu lar
cross-sections. The Lock check box lets you lock
the aspect ratio. When Lock is turned on, Width
is locked to Depth that results in a constant ratio
of Width to Depth.
Lengt h—Specifies the size of the cross–section
along the local Y axis.
Width—Specifies the size of t he cross–sect ion
along the local X axis.
Angle—Adjusts the rotational position of the
cross-section in the viewport or renderer. For
example, if you have a square cross-sect ion you
can use Angle to position a "flat" side down.
Auto Smooth—If Auto Smooth is turned on, the
spline is auto-smoothed using the threshold
specified by the Threshold setting below it. Auto
Smooth sets the smoothing based on the angle
between spline segments. Any two adjacent
segmentsareputinthesamesmoothinggroupif
the angle between them is less t han the threshold
angle.
Threshold—Specifies the threshold angle in
degrees. Any two adjacent spline segments are put
inthesamesmoothinggroupiftheanglebetween
them is less than the threshold angle.
