pointtransformrigid

Since	18.5

matrix  pointtransformrigid(<geometry>geometry, int pnt)

Returns a rigid transform associated with the point index. This function uses the standard instancing point attributes to build the matrix, and polar decomposition is performed to make it rigid.

<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.

pnt

The point index to query.
