int agentrigparent(<geometry>geometry, int prim, int transform)
Returns -1 if transform is a root of the transform hierarchy, transform is out of range, prim is out of range, or prim is not an agent primitive.
<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.
prim
The primitive number.
transform
Index of a transform in the agent’s rig.
Examples ¶
Find the world transform of the rig’s root, beginning from a given bone.
int root; while (true) { int parent = agentrigparent(0, @primnum, transform); if (parent < 0) { root = transform; break; } else transform = parent; } matrix root_xform = agentworldtransform(0, @primnum, root);
