VisITMeta

VisITMeta is an experimental IF-MAP 2.0/2.1 compliant MAP client written in Java that visualizes metadata stored on a MAP server. It supports features like showing a history of all metadata stored on a MAPS, using filter and search techniques to navigate the metadata as well as some visualization techniques like animations, highlighting and so on. Development was done by Hochschule Hannover (University of Applied Sciences and Arts, Hanover) within the VisITMeta research project, (support code 17PNT032) which is funded by the german BMBF (Federal Ministry of Education and Research).

VisITMeta input device: LeapMotion

This project adds support for the LeapMotion input device controller to the VisITMeta GUI. It uses functionality and methods from the SDK v1.

Building

This section describes, how to build LeapMotion for VisITMeta from scratch.

Prerequisites

In order to build VisITMeta with Maven you need to install Maven 3 manually or via the package manager of your operating system.

Furthermore, you need to download the LeapMotion SDK v1 suitable to your platform and operating system.

Extract the SDK archive into a folder of your choice.

Copying files form the SDK

Go to the src/main/templates/native-libs/ folder inside this project (where this README lies).

There should exist three folders named linux, osx and windows. Switch to the one suitable for your operating system and choose the subdirectory for your system architecture (x64 or x86).

Example: If you are on a 64bit Linux system, the folder src/main/templates/native-libs/linux/x64/ would be the correct one.

Now, go to the the LeapMotion SDK folder you extracted earlier and go to LeapDeveloperKit/LeapSDK/lib.

Depending on your system, you have to copy the following files:

Linux

• libLeap.so and libLeapJava.so from the x64 or x86 folder to native-libs/linux/x64 or native-libs/linux/x86
• LeapJava.jar to native-libs/

Windows

• the x64 or x86 folder to native-libs/windows/
• LeapJava.jar to native-libs/

Mac OSX

• libLeap.dylib and libLeapJava.dylib to native-libs/osx/x64
• LeapJava.jar to native-libs/

Installing LeapMotion for Java into local Maven repository

Afterwards you have to edit the script file for your system under src/main/templates/installation to reflect the correct filename and version of the loaded SDK version.

#!/bin/bash
mvn org.apache.maven.plugins:maven-install-plugin:2.3.1:install-file \
	-Dfile=../native-libs/LeapJava.jar \
	-DgroupId=com.leapmotion.leap -DartifactId=leapmotion \
	-Dversion=1.2.0 -Dpackaging=jar

Furthermore the pom.xml in the projects root directory has to be adapted to that version number in the section

<dependency>
	<groupId>com.leapmotion.leap</groupId>
	<artifactId>leapmotion</artifactId>
	<version>1.2.0</version>
</dependency>

Build LeapMotion for VisITMeta

Now you can build the LeapMotion for VisITMeta-module by executing:

$ mvn package

in the root directory of the LeapMotion for VisITMeta project (the directory containing this README file). Maven should download all further needed dependencies for you. After a successful build you should find a zip-archive called visitmeta-device-leapmotion-<version>-bundle.zip in target.

Copy this archive to the devices subfolder of your already build VisITMeta folder and extract it.

Configuration

This section describes the configuration options of the LeapMotion for VisITMeta module.

Running

Start the VisITMeta GUI via

$ sh start-visualization.sh

The log output should tell you that the LeapMotion controller was loaded, unless there was an error.

Just select a running connection from the treeview on the left side and try to use the LeapMotion controller to navigate/move the graph.
