Fish-eye views
A common problem of scaling operations is that zooming on a focus often results in losing sight of important contextual information. That's why aiSee integrates sophisticated graph distortion techniques, which imitate the well-known fish-eye lens effect: A focus area is magnified while other parts of the graph are displayed with less detail. Thus, enabling the user to concentrate on areas of particular interest while still considering their context.
The graph appears in the graph window, the window depicting a distorted coordinate system, consequently distorting the image of the graph. The main point of interest is the focus, the focus being magnified and shown in detail. The parts of the graph that are further away from the focus appear slightly squashed, meaning the further nodes are positioned away from the focus, the smaller they appear in the graph window.
Consequently, the relation between the original graph and the visible image of the graph is not linear, but rather depends on the distance from the focus. This mechanism is similar to the fish-eye lenses used in photography.
Browsing through a fish-eye view involves moving the focus. This can be done very easily via Picking Position.

Cartesian fish-eye view Cartesian fish-eye view corresponds to a transformation of the Cartesian coordinate system. In a Cartesian view, horizontal and vertical lines are still drawn as parallel horizontal and vertical lines. Many layouts are based on orthogonal lines. This view improves the readability of such layouts. |

Polar fish-eye view Polar fish-eye view corresponds to a transformation of the polar coordinate system, a transformation in which the plane of a normal coordinate system is projected onto a sphere. The polar fish-eye view corresponds to a three-dimensional view onto this sphere. In a polar view, horizontal and vertical lines do not necessarily appear orthogonal. |
