Additional Field Attributes

 
 
 

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.
