We are researching multiple methods for dynamically visualizing |

the structure. |

We use buoys as link targets floating around the focus. |

|
What we call *buoy* is a commonly used tool in technical diagrams: |
241 |
|
placing a label at the edge of the image and connecting the label |
242 |
|
to the relevant location (anchor) by a line (see Fig. [ref-fignasa]_).. |
243 |
|
We research the geometry and layout of the buoy placement |
244 |
|
for coherent views and animation. |

*Break lines* are a technique used in technical drawing |
247 |
|
for indicating |
248 |
|
where an object extends beyond what is drawn in the current |
249 |
|
diagram. It is visually clear since it uses a shape that |
250 |
|
is obviously not a part of the object's own shape |
251 |
|
(wiggly freehand line, see Fig. [ref-fignasa]_). |
252 |
|
We apply this technique by drawing the buoys as |
253 |
|
non-photorealistical pieces torn off the target document. |
254 |
|
To allow for fluid animation, |
255 |
|
the shapes of the break lines need to be carefully designed. |
