How to declare python variable for Vector

dan.husted — Mon, 04 Feb 2019 22:30:23 GMT

I am trying to call the function addRotationControlPoint but can't figure out exactly what it wants for the rotation vector variable. The response I get when I pass an array on 3 floats is :

Boost.Python.ArgumentError: Python argument types in
vrAnimWidgets.addRotationControlPoint(vrNodePtr, float, array.array)
did not match C++ signature:
addRotationControlPoint(class osg::NodePtr node, float time, class osg::Vector<float,3> rot)

With other functions I am able to pass it a list, but that doesn't seem to work with this one.

A little help?

It should work by just using Vec3f(1.0, 2.0,3.0) for a vector with 3 floats.

Kind regards

Michael

Well that was easy. Thanks for your swift response.
