synopsis.
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.

Properties |
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. |
