Usage ¶
setInputCurvePositions(session: hapi.Session, node_id: int, part_id: int, positions_array: list of float, start: int, length: int) → bool
Sets the positions for input curves, doing checks for curve validity, and adjusting the curve settings accordingly. Will also cook the node.
session
The session of Houdini you are interacting with. See hapi.Session for more on sessions. Pass None to just use the default in-process session.

A float array representing the positions attribute. It will read the array assuming a tuple size of 3. Note that this function does not do any coordinate axes conversion.
start
The index of the first position in positions_array.
