I set the widgetFactory manipulator plane to use the camera normal, I want to get this normal through getNormal, how do I do it

I set useCameraNormal, I need to get it somewhere, using getNormal, what should be passed in the calldata parameter?

How can I get the normals of this widgetFactory

If you use useCameraNormal then callData won’t be used, getNormal() will return the camera normal. You can therefore pass {} as callData. Otherwise, you can look at the implementation of getNormal() for the manipulator you have instanced and see what callData it relies on (typically a mouse event call data)

Ok, i see, thank you very much
