int [] uniquevals(<geometry>geometry, string attribclass, string attribute_name)
string [] uniquevals(<geometry>geometry, string attribclass, string attribute_name)
If any points/primitives/vertices in the geometry have the same value for the given attribute, the set of unique values will be smaller than the total number of points/primitives/vertices. This function lets you acquire the set of unique values.
This function only works with string and integer attributes.
<geometry>
When running in the context of a node (such as a wrangle SOP), this argument can be an integer representing the input number (starting at 0) to read the geometry from.
Alternatively, the argument can be a string specifying a geometry file (for example, a .bgeo
) to read from. When running inside Houdini, this can be an op:/path/to/sop
reference.
attribclass
One of "detail"
(or "global"
), "point"
, "prim"
, or "vertex"
.
You can also use "primgroup"
, "pointgroup"
or "vertexgroup"
to read from groups.
attribute_name
The name of the attribute (or intrinsic) to read.
