accessing to the geometry to move points

[pelos]

is the geometry avaible for modification? i try to move point 0 from a box to a specific position but i do get the error that said that geometry is read only. i am assuming like word documents might be a way to change that. so we can modify the document.

>>> node=hou.node('/obj/box')

>>> node = node.node("box1")

>>> nodeGeo = node.geometry()

>>> nodeGeo0 = nodeGeo.iterPoints()[0]

>>> nodeGeo0.setPosition([1,1,1])

Traceback (most recent call last):

File "<console>", line 1, in <module>

File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.125/houdini/python2.6libs\hou.py", line 25745, in setPosition

return _hou.Point_setPosition(*args)

GeometryPermissionerror: Geometry is read-only.

You can only modify geometry with Python from inside a Python SOP.

Ah... and do we have a "python sop" o do we have to create one from the script node?
