Synopsis

polyContourProjection [-caching boolean] [-constructionHistory boolean] [-createNewMap boolean] [-flipRails boolean] [-insertBeforeDeformers boolean] [-method int] [-name string] [-nodeState int] [-offset0 linear] [-offset1 linear] [-offset2 linear] [-offset3 linear] [-reduceShear float] [-smoothness0 float] [-smoothness1 float] [-smoothness2 float] [-smoothness3 float] [-userDefinedCorners boolean] [-worldSpace boolean]

polyContourProjection is undoable, queryable, and editable.

Return value

In query mode, return type is based on queried flag.

Flags

Long name (short name)	Argument types	Properties
-createNewMap(-cm)	boolean
This flag when set true will create a new map with the name passed in, if the map does not already exist.
-flipRails(-fr)	boolean
If true, flip which curves are the rails of the birail surface.
-insertBeforeDeformers(-ibd)	boolean
This flag specifies if the projection node should be inserted before or after deformer nodes already applied to the shape. Inserting the projection after the deformer leads to texture swimming during animation and is most often undesirable. C: Default is on.
-method(-m)	int
Sets which projection method to use. Valid values are 0: Walk Contours 1: NURBS Projection
-offset0(-o0)	linear
Sets the offset on edge 0 of the NURBS surface.
-offset1(-o1)	linear
Sets the offset on edge 1 of the NURBS surface.
-offset2(-o2)	linear
Sets the offset on edge 2 of the NURBS surface.
-offset3(-o3)	linear
Sets the offset on edge 3 of the NURBS surface.
-reduceShear(-rs)	float
Sets the 'reduce shear' parameter of the projection.
-smoothness0(-s0)	float
Sets the smoothness of edge 0 of the NURBS surface.
-smoothness1(-s1)	float
Sets the smoothness of edge 1 of the NURBS surface.
-smoothness2(-s2)	float
Sets the smoothness of edge 2 of the NURBS surface.
-smoothness3(-s3)	float
Sets the smoothness of edge 3 of the NURBS surface.
-userDefinedCorners(-udc)	boolean
If true, the four vertices specified by user will be taken as corners to do the projection.
-worldSpace(-ws)	boolean
This flag specifies which reference to use. If on : all geometrical values are taken in world reference. If off : all geometrical values are taken in object reference. C: Default is off. Q: When queried, this flag returns an int.
Common flags
-caching(-cch)	boolean
Toggle caching for all attributes so that no recomputation is needed.
-constructionHistory(-ch)	boolean
Turn the construction history on or off (where applicable). If construction history is on then the corresponding node will be inserted into the history chain for the mesh. If construction history is off then the operation will be performed directly on the object. Note: If the object already has construction history then this flag is ignored and the node will always be inserted into the history chain.
-name(-n)	string
Give a name to the resulting node.
-nodeState(-nds)	int
Defines how to evaluate the node. 0: Normal 1: PassThrough 2: Blocking 3: Internally disabled. Will return to Normal state when enabled 4: Internally disabled. Will return to PassThrough state when enabled 5: Internally disabled. Will return to Blocking state when enabled

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 be used more than once in a command.
