[ContextCapture] - The workflow to iteratively create a large/more detailed model

I've been reading through the extensive Wiki articles on ContextCapture. Really great! This is a great way to convey info/knowledge of the capabilites of the software. I also noted that a few videos have been published recently on the Acute3D Youtube account:

www.youtube.com/.../Acute3D

This is even more great! Kudos for this eminent way of spreading info!  :-)

Now to my question:

I've tried to get a grip of the (suggested) workflow to compile large models. For example, the huge city-models that can be seen on other Youtube videos and also as web-demos at www.acute3D.com

I assume that these models are created in some iterative way. But how? In this article in the Wiki:

communities.bentley.com/.../27141.contextcapture-add-additional-photos

..the question is noted, but I'm sorry to say I don't really understand what the answer is saying...

So it would be great to see a Wiki article describing this workflow. Or even better - a Youtube video presenting the process.

The reason why I'm interested in this is that we can see a potential in using CC to model complex process plants. In these we foresee that it will be impossible to model [everything] perfect at once. So we foresee a process where we first generate a "draft" model of the basic plant, and then add detail level photos on those parts that we want more accuracy on.

Is this possible to do without constantly re-running the whole set of pics (AT and production)? That would eventually lead to a very long processing of the "last" detail.

Thanks in advance for replies!  :-)
