Discussion: transition smoothly to another parent node

[Goutte]

There are multiple strategies to achieve that.

Some notes

• rewrite stuff to trackball around a target node instead of the parent, like some other cameras do
• right now the transform of the parent is applied, it may well be a feature for some of us
• remove_child, add_child and smooth camera constraint solver ?
• probably best to use another class if the changes are expensive, or can't easily be toggled on/off

[Goutte]

There's perhaps also the usage of three cameras : two trackball cameras, one for each parent, and an interpolated camera for the transitions. I have not tested this.

What I usually do is make the TrackballCamera a child of a Spatial node called Eye or something, and move the Eye around.
