If you know the attribute class ahead of time, using hasdetailattrib, hasprimattrib, haspointattrib, or hasvertexattrib may be faster.
int hasattrib(<geometry>geometry, string attribclass, string attribute_name)
<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.
Returns 1
if the attribute exists, or 0
otherwise.
Examples ¶
// Check whether the point group "pointstouse" exists. if (hasattrib("defgeo.bgeo", "pointgroup", "pointstouse")) { // Do something with the point group }
