int hex_adjacent(<geometry>geometry, int primindex, int faceno)
<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.
primindex
The primitive number.
faceno
The face on the hexahedron. Ranges from 0
to 5
.
Returns
The primitive number of the hexahedron attached to the given face.
Returns -1
f the primitive is not a hex or doesn’t have an adjacent hexahedron.
Use hex_faceindex to get the vertex indices of each face of a hexahedron.
