EdgeSelection Values

An EdgeSelection represents a set of edges for a scene mesh node as a virtual array. As such, you can access an edge by index, iterate over the edges, and apply mapped functions to the edges. See also Editable_Mesh. The EdgeSelection array is dynamic, i.e., its contents will change as the edges or selected edges of the mesh node change. EdgeSelection values are mappable.

Constructors

<mesh>.selectedEdges

The currently selected edges of the mesh object

<mesh>.Edges

All of the edges of the mesh object, read-only

Properties

<edgeselection>.count : Integer, read-only

Returns the number of edges in the edge array.

<edgeselection>.selSetNames : Array of names, read-only

Returns an array of names of the current edge-level named selection sets for the object the EdgeSelection is associated with.

The following property is present for singleton selections (of the form $foo.edges[n]):

<edgeselection>.index : Integer, read-only

Returns the index of the selected element in the mesh,

For example

$foo.selectedEdges[2].index

returns the edge index of the 2nd edge in the current selection.

Note

that iterating over a selection yields singleton selections in the loop body:

se = for i in $foo.selectedVerts collect i.index

--se contains selected edges as array

Operators

<mesh>.selectedEdges = (<array> | <bitarray>)

Selects the specified edges.

<edgeselection>[<integer>]

Retrieves the indexed edge as a singleton EdgeSelection. Index starts at 1

<edgeselection>[(<integer_array> | <bitarray>)]

Retrieves the indexed edges as a EdgeSelection. Index starts at 1.

<edgeselection>[(<#name> | <string>)]

Retrieves the edge-level named selection set, where the name of the named selection set can be specified as a name or string value.

<edgeselection>[(<#name> | <string>)] = (<faceselection> | <integer_array> | <bitarray>)

Sets the edge-level named selection set to the specified edges. The name of the named selection set can be specified as a name or string value, and the edges can be specified as an array, bitArray, or a EdgeSelection from the same object.

Methods

move <edgeselection> <point3>

Moves the edges in the EdgeSelection.

select <edgeselection>

Selects the edges in the EdgeSelection.

deselect <edgeselection>

Deselects the edges in the EdgeSelection.

delete <edgeselection>

Deletes the edges in the EdgeSelection.

append <edgeselection> (<edgeselection> | <integer>)

Appends the edge(s) to the EdgeSelection.

findItem <edgeselection> (<edgeselection[<integer>] | <integer>)

Returns the selection index of the matching item or 0 if not found. The item is selection index or singleton EdgeSelection.

Examples

-- move edges in 'mouth' named selection set

move $foo.edges[#mouth] [0,0,10]

-- select edges in 'front edges' set

select $baz.edges["front edges"]

-- set 'baz' named selection set to given edges

$foo.edges[#baz] = #(1,3,4,5,10)

-- set 'cursel' set to current selection

$baz.edges[#cursel] = $baz.selectedEdges

-- all the names of the edge-level named selection sets for object $foo

$foo.edges.selSetNames

-- print out all edge-level named selection sets

for n in $.edges.selSetNames do print $.edges[n]
