  • Dynamic Wizard Modeling with GMF

    Eclipse Magazine

    *This article also re-appeared in Best of Volumes 1-9*

    Developing a graphical editor is generally very complicated and requires lot of effort. There are few frameworks available for writing graphical editors in Java. The prominent open source frameworks are JHotDraw (which is Swing based) and GEF (which is SWT/Jface-based). While they provide sophisticated tools for graphical development, the painstaking work of modeling the domain and mapping to graphical elements is left to the user…

    Developing a graphical editor is generally very complicated and requires lot of effort. There are few frameworks available for writing graphical editors in Java. The prominent open source frameworks are JHotDraw (which is Swing based) and GEF (which is SWT/Jface-based). While they provide sophisticated tools for graphical development, the painstaking work of modeling the domain and mapping to graphical elements is left to the user. Graphical Modeling Framework (GMF) bridges this gap nicely. In the article, I will take you through an end-to-end demonstration of GMF. To achieve that, first we will create a framework for meta-data driven JFace wizards. Next, we will see how to use GMF to build a graphical editor for this framework.

  • Using Tcl to build a buzzword compliant environment that glues together legacy analysis programs

    Proc. 7th Intl Tcl/Tk Conference, Austin, Texas: USENIX

    The Siemens Integrated Design (SID) Environment is a system that allows engineers to link together many legacy computer programs. This capability provides significant reduction in effort for defining the conceptual design of electrical generators. The SID environment is a generic tool for running all types of analysis programs (methods) as well as managing their associated data. Methods are plugged into the environment in a simplified fashion by using a well-defined interface. Any features that…

    The Siemens Integrated Design (SID) Environment is a system that allows engineers to link together many legacy computer programs. This capability provides significant reduction in effort for defining the conceptual design of electrical generators. The SID environment is a generic tool for running all types of analysis programs (methods) as well as managing their associated data. Methods are plugged into the environment in a simplified fashion by using a well-defined interface. Any features that are added to the environment immediately benefit all methods. Data can be shared between remote sites through an in-house developed, java based, replication server. This paper discusses how Tcl was used to develop the SID Environment and why it was the best choice for our application.

  • Multiresolution Representation of Non-Uniformly Sampled Terrain Databases Using Wavelets

    Thirtieth Asilomar Conference on Signals, Systems and Computers (IEEE), Monterey, CA

    Terrain databases contain data of a terrain which may be uniformly or non-uniformly sampled. In the case of non-uniformly sampled terrains, the resulting structure is a TIN (triangulated irregular network). Since a typical terrain database may contain a large number of triangles, it is often difficult to visualize and organize them. We propose the usage of wavelets in terrain databases to construct hierarchical representations of the terrain skin. It is observed that the resulting structure…

    Terrain databases contain data of a terrain which may be uniformly or non-uniformly sampled. In the case of non-uniformly sampled terrains, the resulting structure is a TIN (triangulated irregular network). Since a typical terrain database may contain a large number of triangles, it is often difficult to visualize and organize them. We propose the usage of wavelets in terrain databases to construct hierarchical representations of the terrain skin. It is observed that the resulting structure enables easy construction of multiple LODs (level of details) automatically and also has various other uses like polyhedral compression.
