agentrigparent

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

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);
