polyMergeVertex([alwaysMergeTwoVertices=boolean], [caching=boolean], [constructionHistory=boolean], [distance=linear], [mergeToComponents=string], [name=string], [nodeState=int], [texture=boolean])
Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.
polyMergeVertex is undoable, queryable, and editable.
Merge vertices within a given threshold.
Since this allows merging any vertices that lie on the same object it
is possible for the resulting geometry to be non-manifold.
First, perform comparison of pairs of selected vertices.
Pairs that lie within given distance of one another are merged,
along with the edge between them.
Second, any selected vertices which share an edge are merged if
the distance between them is within the specified distance.
Unlike Merge Edges, Merge Vertices will perform the merge even if the
edges adjoining the vertices do not have matching orientation (i.e.
normals of adjacent faces do not point in the same direction). As this
restriction is not enforced while merging vertices, resulting geometry
can be non-manifold.
If alwaysMergeTwoVertices is set and there are only two vertices, tolerance
is ignored and the vertices will be merged.
Resulting mesh may have extra vertices or edges to ensure
geometry is valid.
In query mode, return type is based on queried flag.

Properties |
distance(d)
|
linear
|
  
|
|
This flag specifies the distance within which vertices will be merged.
C: Default is 0.0 (i.e. vertices are coincident).
Q: When queried, this flag returns a double.
|
|
alwaysMergeTwoVertices(am)
|
boolean
|
|
|
This flag specifies whether to always merge if only two vertices are
selected regardless of distance.
C: Default is false.
Q: When queried, this flag returns a boolean.
|
|
texture(tx)
|
boolean
|
|
|
This flag specifies whether the texture is sewn in addition to the 3d edge
C: Default is true.
Q: When queried, this flag returns a boolean.
|
|
mergeToComponents(mtc)
|
string
|
|
|
Optionally defines the position to merge all of the vertices to. If set, the distance
flag will be ignored, and instead the center point of the set components will be
calculated and all vertices will be merged to that location.
C: Default is empty string.
Q: When queried, this flag returns a string.
|
|
| Common flags |
name(n)
|
string
|
|
|
Give a name to the resulting node.
|
|
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.
|
|
caching(cch)
|
boolean
|
|
|
Toggle caching for all attributes so that no recomputation is needed
|
|
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
