nonLinear is undoable, queryable, and editable.
This command creates a functional deformer of the specified type
that will deform the selected objects. The deformer consists of
three nodes: The deformer driver that gets connected to the history
of the selected objects, the deformer handle transform that
controls position and orientation of the axis of the deformation
and the deformer handle that maintains the deformation parameters.
The type of the deformer handle shape created depends on the
specified type of the deformer. The deformer handle will be
positioned at the center of the selected objects' bounding box and
oriented to match the orientation of the leading object in the
selection list. The deformer handle transform will be selected when
the command is completed. The nonLinear command has some flags
which are specific to the nonLinear type specified with the -type
flag. The flags correspond to the primary keyable attributes
related to the specific type of nonLinear node. For example, if the
type is "bend", then the flags "-curvature", "-lowBound" and
"-highBound" may be used to initialize, edit or query those
attribute values on the bend node. Examples of this are covered in
the example section below.

Argument types |
Properties |
name(n) |
string |
 |
|
Used to specify the name of the node being created |
|
geometry(g) |
string |
   |
|
The specified object will be added to the list of objects being
deformed by this deformer object, unless the -rm flag is also
specified. When queried, this flag returns string string string
... |
|
geometryIndices(gi) |
boolean |
|
|
Complements the -geometry flag in query mode. Returns the multi
index of each geometry. |
|
remove(rm) |
boolean |
|
|
Specifies that objects listed after the -g flag should be
removed from this deformer. |
|
before(bf) |
boolean |
|
|
If the default behavior for insertion/appending into/onto the
existing chain is not what you want then you can use this flag to
force the command to stick the deformer node before the selected
node in the chain even if a new geometry shape has to be created in
order to do so. Works in create mode (and edit mode if the deformer
has no geometry added yet). |
|
after(af) |
boolean |
|
|
If the default behavior for insertion/appending into/onto the
existing chain is not what you want then you can use this flag to
force the command to stick the deformer node after the selected
node in the chain even if a new geometry shape has to be created in
order to do so. Works in create mode (and edit mode if the deformer
has no geometry added yet). |
|
afterReference(ar) |
boolean |
|
|
The -afterReference flag is used to specify deformer ordering
in a hybrid way that choses between -before and -after
automatically. If the geometry being deformed is referenced then
-after mode is used in adding the new deformer otherwise -before
mode is used. The net effect when using -afterReference to build
deformer chains is that internal shape nodes in the deformer chain
will only appear at reference file boundaries, leading to
lightweight deformer networks that may be more amicable to
reference swapping. |
|
split(sp) |
boolean |
|
|
Branches off a new chain in the dependency graph instead of
inserting/appending the deformer into/onto an existing chain. Works
in create mode (and edit mode if the deformer has no geometry added
yet). |
|
frontOfChain(foc) |
boolean |
|
|
This command is used to specify that the new deformer node
should be placed ahead (upstream) of existing deformer and skin
nodes in the shape's history (but not ahead of existing tweak
nodes). The input to the deformer will be the upstream shape rather
than the visible downstream shape, so the behavior of this flag is
the most intuitive if the downstream deformers are in their reset
(hasNoEffect) position when the new deformer is added. Works in
create mode (and edit mode if the deformer has no geometry added
yet). |
|
parallel(par) |
boolean |
|
|
Inserts the new deformer in a parallel chain to any existing
deformers in the history of the object. A blendShape is inserted to
blend the parallel results together. Works in create mode (and edit
mode if the deformer has no geometry added yet). |
|
ignoreSelected(ignoreSelected) |
boolean |
|
|
Tells the command to not deform objects on the current
selection list |
|
deformerTools(dt) |
boolean |
|
|
Returns the name of the deformer tool objects (if any) as
string string ... |
|
prune(pr) |
boolean |
|
|
Removes any points not being deformed by the deformer in its
current configuration from the deformer set. |
|
exclusive(ex) |
string |
|
|
Puts the deformation set in a deform partition. |
|
type(typ) |
string |
|
|
Specifies the type of deformation. The current valid
deformation types are: bend, twist, squash, flare, sine and
wave |
|
commonParent(cp) |
boolean |
|
|
Creates a new transform and parents the selected object and the
deformer handle under it. This flag is valid only when a single
object is selected. |
|
autoParent(ap) |
boolean |
|
|
Parents the deformer handle under the selected object's
transform. This flag is valid only when a single object is
selected. |
|
defaultScale(ds) |
boolean |
|
|
Sets the scale of the deformation handle to 1. By default the
deformation handle is scaled to the match the largest dimension of
the selected objects' bounding box. [deformerFlags] The attributes
of the deformer handle shape can be set upon creation, edited and
queried as normal flags using either the long or the short
attribute name. e.g. |
|
| Flag can appear in Create mode of
command |
Flag can appear in Edit mode of command |
| Flag can appear in Query mode of command |
Flag can have multiple arguments, passed
either as a tuple or a list. |
