Description |
This tool can be used to visualize a number of different decompositions. The main visualization window is zoomable and the user can optionally overlay it with a grid. There are a number of operations that can be performed. Users can insert, move and delete rectangles that define the structure. In addition, the user can perform three test, near, within and overlap. For the tests, the user is given the option of what kind of shape to use for the test: point, rectangle, polygon, path, etc. The application of the tests is animated, with controls given for pausing the animation and controlling the speed. In addition, the animation can be made to stop at logical phase points (such as when an object is encountered. |

Evaluation |
Users can easily enter rectangles and see the R-tree deocmposition. Unfortunately, there is very little feedback about what is going on. It would be a big help if there were some form of textual log that explains the steps taking place. Even some kind of description of the basic operations would be good. The interface is generally good, but has some confusing aspects. There is helpful explanatory text on the page to give some background. |
