Abstract
Natural phenomena like earthquakes or floods cannot be avoided or controlled by humans
but ignoring them can be fatal. In order to understand their characteristics and
behavior computer simulations can be used. The gained knowledge is used to find
strategies and countermeasures to minimize the damage caused by such disasters.
Visdom is a modular integrated visualization system which is developed to support the
analysis of flood simulations. It provides the ability to test different decisions made
by the user for example the establishment of barrier arrangements. These alternative
scenarios can be visualized and analyzed in order to find the solution which minimizes
damage in the vicinity. For modifying the flood, the simulation parameters have to be
varied. In Visdom, this has to be done by inserting numeric values into textfields or
using sliders. In most cases, the system is intended to be used in time-critical situations
where fast interaction and testing is required. Therefore a sketch-based interface
is introduced into Visdom which should simplify and accelerate the modification of simulation
parameters. This kind of interaction increases the productivity and efficiency of
the whole work-flow due to its intuitive and straightforward usage.
Since Visdom is based on a modular data-flow system, the new functionality is implemented
within a new node. The so-called Spline Node provides methods to create
and manipulate a spline. It requires the drawn user input points which are captured by
a view node. Due to the fact that Visdom is based on the data-flow concept, a new
mechanism called Modular Interactors has to be introduced to enable interaction communication
between nodes especially upstream. In order to support the user during the
sketching process the system provides visual feedback. The sketched stroke is represented
using a tubular geometry which is directly visualized in the 3D view.
