Rapid Visualization Development based on Visual Programming

Developing a Visualization Prototyping Language (DAEV) Benedikt Stehno

Title Goal Idea OpenInsightExplorer Features Evaluation Conclusion

Goal

To develop a multi (cross) platform rapid visualization prototyping language (OpenInsightExplorer) easy to use (non programmers) extendable

  • pen source

automatic parallelization supports hardware acceleration (GPU) custom data types

Title Goal Idea OpenInsightExplorer Features Evaluation Conclusion

Idea

combine the powers of ... a modular approach visual programming dataflow programming ... to a Dataflow Visual Programming Language (DFVPL)

Title Goal Idea OpenInsightExplorer Features Evaluation Conclusion

Idea

Each module (or patch) represents a stage of the visualization pipeline works as an independent black box communicates with other modules (over ports) is arranged and connected in a visual editor (visual programming) is executed as soon as data is available (dataflow execution) Programming becomes the task to visually connect a custom pipeline together

Features

Features of OpenInsightExplorer

  • pen source and platform independence

automatic parallelization custom data types java classes as data type data streams type-safety easy patch / library installation

slide-8

Title Goal Idea OpenInsightExplorer Features Evaluation Conclusion

Features

Unique features of OpenInsightExplorer easy to develop modules (Patch interface) delegating Patches patch GUIs Growing Ports Port Trees Generic Ports

slide-9
SLIDE 9

Title Goal Idea OpenInsightExplorer Features Evaluation Conclusion

Features

Patch Interface Only a small Java interface must be implement to write a patch. Similar to the Java Applet interface (run(), init(), stop(),...). Delegating Patches Patches can sent functionality (Methods, ...). Allows to split and combine tasks between patches.

Conclusion

Conclusion Still too complex for none programmers State-of-the-art DFVPL features are missing (debugging, structured programming, ...) Arbitrary synchronization/execution between patches Execution overhead increases fast (only good for prototyping) Generic Ports and Growing Ports improve the reuse of patches a lot
