[IPython-dev] Conflict between IPython notebook javascript and three.js?

[Patrick Fuller]

In case it helps, here are two projects that work the way you want with
trackball: imolecule <http://patrick-fuller.com/imolecule/> and igraph
<http://patrick-fuller.com/igraph/>. The code of interest is here
<https://github.com/patrickfuller/igraph/blob/master/python/notebook.py#L70-L95>.
It’s been a while since I’ve looked at this, but I believe my trick was to
use _repr_html_ instead of _repr_javascript_ in order to make a new div.

Hope this helps,
Pat
