Convert RBDs (Fetch Packed Geometry from DOP network style) to instancepoints. Pretty sure this is lifted from one of Henry Foster (Toadstorm)'s odforce/sidefx forum replies.

rbd_to_instancepoints.h

// Get packed xform and pivot
matrix xform = getpackedtransform(0, i@ptnum);
vector pivot = primintrinsic(0, "pivot", i@ptnum);

//  Orient for instancing
p@orient = quaternion(matrix3(xform));

// Crack pscale
vector scale = cracktransform(0, 0, 2, 0, xform);
f@pscale = avg(scale);

// Offset P by pivot difference
vector new_pivot = {0, 0, 0};
vector offset = new_pivot - pivot;
v@P = offset * xform;
