## Feedback to JavaView

JavaViewLib - A
Maple Powertool Version 3.0 in May 2005 |
The joint cooperation with Steve Dugaro lead to JVL which is now an official Maple Research Powertool available from Waterloo Maple since 2002. |

"JavaView provides a simple and efficient method to visualize
and precisely determine the distance between two points on a
surface of a 3D body like an honeybee observation hive. Standard spread
sheet software is less precise because JavaView provides the shortest way.
In every projection we used to transfer the 3D bee hive in a 2D space, we
had the problem that we made presumption about the walking patterns. So
bees which were not following these patterns were not included in our
model. These disadvantage is one of the major advantages of JavaView.
Moreover, JavaView gives us more than only a perfect way to calculate
distances between to points, it is easy to handle and easy to adjust to
specific changes. With the visualizations we are able to make comparisons
between the theoretical (shortest way, JavaView) and the observed one.
Also, we can follow the worker position compared to the queen position so
we can easily investigate, if special workers kept away from the queen in
a specific pattern, e.g. the worker was always between entrance and queen. In conclusion, I can say that with JavaView it is easier and it gives a new point of view, resulting in new biological questions and answers." |

"I like JavaView's extreme flexibility as far as file formats and object types are concerned. Moreover, it can be used in very many ways. I am particularly fond of the possibility to make interactive web pages with my favorite geometric toys. JavaView goes way beyond the capabilities of similar tools I used to work with." |

The application described below is available for free on the
web - I installed it in my PC. It enhanced the experience I have with
Maple plots in a quite noticeable manner, so perhaps this is interesting
for others too. The application is described at
www.javaview.de/maple.
Quoting from that web page - a brief description is "JavaView provides a superior viewing environment to augment and enhance the plot of geometrical objects in Maple. It provides several features that are non-existent in the Maple plotter, such as mouse controlled scaling, translation, and auto view modes. JavaView implements arc-ball rotation, making object viewing smoother and less directionally constrained than in Maple. Furthermore, JavaView offers a point modeling feature that allows plots to be manually manipulated. The predominant feature of the JavaViewLib is the capacity to export Maple generated models into one of two applet based viewers - one optimized for speed, the other for customizability. This greatly enhances the current state of plot object export in Maple - no longer do dynamic plots need to be converted to static images when creating html pages from Maple worksheets. etc... With JavaViewLib, models created in other modeling applications such as Maya and Mathematica, can easily be imported into Maple's viewing environment" Me again. To the description above I would add: I can manipulate the plot just touching some hot keys, can - by right click + menu - open many views of the same plot, one animated, another scaled, one rotated one whatever.. all of them with natural smooth zooming with the mouse and etc. It is possible to naturally transform into an experiment the curiosity one typically has when looking at plots. Really impressive. I remember I wanted some of these features when programming the plotting routines for Poincar sections - DEtools[poincare] - and reprogramming PDEtools[PDEplot] to handle nonlinear 1st order PDEs too. And so I spent some time preparing DEtools[zoom] and a routine to export Maple plots to GraphWin in order to enhance the visualization. That was better than nothing but I see it is a tiny thing if compared what this JavaView seems to cover naturally. I'm really glad to see this application around. Steve Dugaro (CECM) and Konrad Polthier (TU-Berlin): nice work yours! |
