The following attributes
are not available in Field option windows. After you create a field,
you can adjust these attributes using the field's Attribute Editor.
Volume Trapping
When using a volume shape
field, you can set volume trapping properties to keep objects from
exiting the volume field. Trapping properties work with all volume
shapes and volume curves.
- Trap Inside
-
Applies a force to the volume
field that keeps objects inside the volume. When Trap Inside is
set to a value greater than 0, Trap Radius and Trapped
Ends become available.
- Trap Radius
-
Sets the radius (as
a local space distance) from the volume boundary within which the Trap Inside force
is applied.
- Trap Ends
-
Creates ends on volume cylinders,
cones, and curves that trap objects inside the volume or curve.
Axial Magnitude
Creates a ramp which
scales field Magnitude along the volume
axis.
- Selected Position
-
This value indicates
the position of the field Magnitude on
the ramp. For a volume curve, the left position on ramp represents
the field Magnitude at the base of the
curve, while the right position on the curve represents the field Magnitude at
the tip of the curve. For volume cylinders, the left position on
the ramp represents the field Magnitude at
the cylinder's bottom, while the right position on the ramp represents
the field Magnitude at the cylinder's top.
- Selected Value
-
This value indicates
field Magnitude at the Selected Position.
Interpolation
Controls the way field Magnitude blends between
positions on the ramp. The default setting is Linear.
- None
-
The Axial Magnitude curve
is flat between points.
- Linear
-
The Magnitude values
are interpolated with a linear curve.
- Smooth
-
The Magnitude values
are interpolated along a bell curve, so that each value on the ramp
dominates the region around it, then blends quickly to the next Magnitude value.
- Spline
-
The values are interpolated
with a spline curve, taking neighboring indices into account for
greater smoothness.
Curve Radius
Creates a ramp which
scales the Section Radius of a volume
axis curve. The Curve Radius ramp is only applicable
to volume field curves.
- Selected Position
-
This value indicates
the position of the Section Radius value. The left
position on ramp represents the Section Radius at
the base of the curve, while the right position on the curve represents the Section
Radius at the tip of the curve.
- Selected Value
-
This value indicates Section
Radius value at the Selected Position.
Interpolation
Controls the way field Section
Radius blends between positions on the ramp. The default setting
is Linear.
- None
-
The Curve Radius curve
is flat between points.
- Linear
-
The volume curve radius values
are interpolated with a linear curve.
- Smooth
-
The radius values are interpolated
along a bell curve, so that each value on the ramp dominates the
region around it, then blends quickly to the next radius value.
- Spline
-
The values are interpolated
with a spline curve, taking neighboring indices into account for
greater smoothness.
