ConnectionViewer

ConnectionViewer uses a very simple ASCII file format for Coordinates, Matrices and Vectors, which is implementable in every programming language in a couple of minutes, a description is here: http://gcsc.uni-frankfurt.de/Members/mrupp/connectionviewer/mat-file-format-description

Here's also a sample gallery : http://gcsc.uni-frankfurt.de/Members/mrupp/connectionviewer/samples

Bash for ConnectionViewer

java -jar <PATH>/ConnectionViewer/ConnectionViewer.jar %f

ConnectionViewer as VRL-Plugin

ConnectionViewer provides a VRL-Studio plugin that can be used to visualize ConnectionViewer as reflection-based component in a .vrlp-project. Additionally, the full UI is availiable from the tool menu.

Building ConnectionViewer

Requirements

• JDK >= 1.8
• Internet connection (dependencies are downloaded automatically)
• IDE: Gradle Plugin (not necessary for command line usage)

IDE

Open the ConnectionViewer core Gradle project in your favourite IDE (tested with NetBeans 8.2 and IntelliJ 2018) and build it by calling the assemble task.

Command Line

Navigate to the ConnectionViewer core Gradle project (i.e., path/to/ConnectionViewer) and enter the following command

Bash (Linux/macOS/Cygwin/other Unix shell)

bash gradlew assemble

Windows (CMD)

gradlew assemble 

Install VRL-Studio plugin via Gradle

To install ConnectionViewer as VRL-Studio plugin via gradle, call the installVRLPlugin task and (re)start VRL-Studio.

Some documentation:

• Connections: Turning this on/off will display / not display the connections between nodes in the window. sometimes displaying a lot of connections can be slow.

• Connections as arrows: will display the connections as arrows. slower, but sometimes more clear than the normal way (since these are "directed")

• Diffusion: Will color the connections depending on the ruge/stueben strength of connection. i.e. you can see anisotropic diffusion in one direction.

• Convection: Will show an arrow pointing into the direction of "algebraic convection". That is: if you have a connection -1.9 to left, +2 to mid, and -0.1 to right, convection is to headed to the left.

• Parallel Nodes: enabling this will color each file from a pmat file differently.

• re-move: when using pmat files, you can move the nodes of one processor by holding shift, clicking the mouse and move it around. re-move will move all nodes in the original position.

• Clip: Will open up a window so you can clip some axes (X, Y, Z clipping). Useful especially in 3d.

• Export: Export the current view to PDF or tex (as tikzpicture). See galery.

• reopen: Reopen the current file. Automatic reload: automatic reload if file changes.

• Arrow Size, Font Size: Change arrow/font size.

• all nodes / N1 / N2: display all nodes or neighborhood 1 / 2 / 3 etc. of the currently selected node(s). useful in 3d.

• all comp: show different components.

• recenter: recenter the loaded file.

• Search node: enter a node you want to see. This node is selected then. Use 2.234 to select node 234 from parallel file 2. Use to selection to zoom to the selected node.
