You are right, Dalay.
My intention was not to force any change by now, but to register a
sugestion for a future "ideal" way to controll stereo camera rig.

> Hi Adriano,
> Those high-level controls are desirable. But I tend to favour first
> implement the core functionality, let users define the ultimate
> workflow that attend their productions and then we sort what is the
> unique need of "Adriano's pipeline" and what is of general interest.
> The same is true for controlling min-maximum pixel separation in
> oppose to setting interocular distance and convergence plane.
> Internally the result is the same so for the initial Multi-View
> feature-set we provide the low level settings (e.g., interocular and
> convergence plane) and leave to the users to build customizable
> solutions for their pipelines.
> We had addons to provide those even before a robust Multi-View was in
> place. I'm confident that solutions built on top of the
> Multi-View/Stereo 3D functionality will be in place in no time.
> That said, if you have the time to build a proper proposal on how
> those controllers would fit in the UI and the pipeline I'm all ears.
