Intrinsic values are similar to attributes, but are computed on-demand by Houdini rather than stored.
<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.
intrinsic_name
The name of the intrinsic to read. For example, "pointattributes"
, "pointcount"
, or "bounds"
.
prim_num
The number of the primitive to read the given intrinsic attribute for.
Returns
The value of the intrinsic attribute, or 0
if the intrinsic does not exist.
