selectionList
newton is undoable, queryable, and editable.
A Newton field pulls an object towards the exerting object with
force dependent on the exerting object's mass, using Newton's
universal law of gravitation.
The transform is the associated dependency node.
Use connectDynamic to cause the field to affect a dynamic object.
If fields are created, this command returns the names of each
of the fields. If a field was queried,
the results of the query are returned. If a field was edited, the field
name is returned.
If object names are provided or the active selection list is non-empty,
the command creates a field for every object in the list and calls
addDynamic to add it to the object. If the
list is empty, the command defaults to -pos 0 0 0.
Setting the -pos flag with objects named on the command line is an error.
In query mode, return type is based on queried flag.

-position(-pos)
|
linear linear linear
|
  
|
|
Position in space where you want to place a field.
The newton then emanates from this position in space rather
than from an object. Note that you can both use -pos
(creating a field at a position) and also provide object names.
|
|
-magnitude(-m)
|
float
|
|
|
|
-attenuation(-att)
|
float
|
|
|
Attentuation rate of field
|
|
-maxDistance(-mxd)
|
linear
|
|
|
Maximum distance at which field is exerted.
-1 indicates that the field has no maximum distance.
|
|
-name(-n)
|
string
|
|
|
|
-perVertex(-pv)
|
boolean
|
|
|
Per-vertex application. If this flag is set true, then each
individual point (CV, particle, vertex,etc.) of the chosen object
exerts an identical copy of the force field. If this flag is set to
false, then the froce is exerted only from the geometric center of
the set of points.
|
|
-minDistance(-mnd)
|
float
|
|
|
Minimum distance at which field is exerted.
Distance is in the denominator of the field force equation.
Setting md to a small positive number avoids bizarre behavior
when the distance gets extremely small.

newton -p -2 0 4;
// Creates a newton field at position (0,2,4) in world coordinates,

newton -e -att 0.98 newtonField1;
// Edits the acceleration value of the field named newtonField1
newton -q -m newtonField1;
// Queries newtonF ield1for its magnitude.
newton -e -mxd 10.0 newtonField1;
// Changes the maximum distance of the field called
// "newtonField1" to 10.0.
newton -m 2.0;
// Creates a newton field with magnitude 2.0 for every active selection.
// If no there are active
// selections, creates such a field at world position (0,0,0).
