For thoese who find this question, if you cannot get the help string by hou.parm("...").tuple().help(), try to use parm.tuple().parmTemplate().help().
Because the help string is stored in parameter template of the original parm.

I'm trying to understand how to rotate the default viewport camera about it's own pivot.
I understand the 'translation' and 'rotation' parameters of the hou.GeometryViewport object, but I'm confused about the 'pivot' parameter. Specifically, I want to rotate the camera around its own pivot without changing its translation position. Can anyone explain what the 'pivot' represents and how I could achieve a rotation about itself? Thanks for any reply.

Ok I got it, it is because I have set parent to mainQtWindow. So simply do not set parent.
