| == Introduction ==
| |
| | |
| ParaView web visualization aims to provide a collaborative remote web
| |
| interface for 3D visualization with ParaView as a server.
| |
| Moreover, this also provide a JavaScript API based on the ParaView scripting
| |
| features and capabilities. Some of the web samples are fully operational
| |
| clients that allow you to create remote web visualization as well as joining
| |
| previously created ones with fully interactive user interface for building
| |
| complex data processing and visualization.
| |
| | |
| == Requirements ==
| |
| | |
| In order to build this software, you will need several external components
| |
| depending on the components that you want to generate. Moreover, you might
| |
| want generate them on a computer and deploy them on another one. Therefore,
| |
| the dependencies are given in the building or in the runtime context.
| |
| In this section we will list all the dependency with its context.
| |
| The management of those dependency will be explained in the build section.
| |
| | |

| | |
| == Building the Application ==
| |
| | |
| The project is hosted at kitware at the following URL
| |
| > http://paraview.org/ParaViewWeb.git
| |
| | |
| You will need to create a clone of this repository before proceeding with the
| |
| next instructions. To do so you can either of the following command line.
| |
| > git clone git://paraview.org/ParaViewWeb.git
| |
| > git clone http://paraview.org/ParaViewWeb.git
| |
| > git clone git@paraview.org:ParaViewWeb.git
| |
| | |
| The application is split into several components.
| |
| * ParaviewAdapter (PWServer)
| |
| ** This is C++ component that can be thought of as the ParaView server process that does the actual visualization. This is indeed an application that links against the ParaView application libraries.
| |
| * WebServer/PWService (PWService)
| |
| ** This is a web service that processes access to the scheduling/managing/monitoring ParaviewAdapter jobs as well as communicating with the Paraview Web client for creating visualizations etc. This component includes client-side javscript/java/flash components for developing web-applications using ParaView.
| |
| * WebServer/PWLauncher (PWLauncher)
| |
| ** This is a web component that allow the user to execute script on the server side with login and password informations. This application can be used to start remote pvserver on any cluster. This service has been inserted in the web page of the PWApp application.
| |
| | |
| Besides these two framework components, we have a collection of sample
| |
| applications that demonstrate the use of these components. We have
| |
| deliberately written these samples using different client-side application
| |
| technologies.
| |
| | |
| * WebServer/PWApp (PWApp)
| |
| ** a Google Web Toolkit (GWT) based visualization application that allow the user to load and process data dynamically with a nice and advanced interactive user interface.
| |
| * WebServer/Samples (PW)
| |
| ** It provides an index page of all the sample available.
| |
| * WebServer/Samples/SimpleJavaScript (PWSimple)
| |
| ** A static web page containing a standalone javascript starting two concurrent visualization session with six renderer based on several technology such as Java, JavaScript, Flash. This application can be used to validate how each renderer is behaving on your machine/browser.
| |
| * WebServer/Samples/Interactive console (PWConsole)
| |
| ** a simple jQuery-based scripting application enabling user to write javascript code to control ParaView inside a JavaScript console.
| |
| * WebServer/Samples/Sandbox (PWSandbox)
| |
| ** a Qooxdoox based sandbox application enabling user to try out the ParaView Javascript scripting capabilities to script visualization pipelines using javascript (similar to PWConsole) application.

| === ParaviewAdapter (PWServer) ===
| |
| | |
| ==== Introduction ====
| |
| | |
| The ParaView adapter is a native application which rely on ParaView. Its
| |
| executable start a ParaView server and wait user interaction by listening
| |
| on a Messaging Service based on ActiveMQ. The automatic launch of this
| |
| executable is done by the WebServer/CoreService application. Therefore,
| |
| the end-user should not care about this application.
| |
| | |
| In order to configure the running process several option are given when
| |
| the application is launched. Those option are given here so sys/admin
| |
| could understand the processes that are running on their servers.
| |
| | |
| PWServer options:
| |
| | |
| --client-identifier : Option used to id the visualization session.
| |
| --base-log-dir : Deprecated (NOT USED ANYMORE)
| |
| --log-level : Logging level that you want in your log files
| |
| [DEBUG, INFO, WARNING, ERROR, CRITICAL]
| |
| --batch-file : Python script that should be executed inside
| |
| the pwhelper.py context
| |
| | |
| ==== Prerequisites ====
| |
| | |
| ===== ActiveMQ-CPP =====
| |
| | |
| ActiveMQ-CPP is needed for the compilation and the execution of the
| |
| application. Therefore, you will need to download the source files at
| |
| the following url http://activemq.apache.org/cms/download.html.
| |
| Then you will need to build that library. The command line given below
| |
| are for Unix systems.
| |
| | |
| > ./configure
| |
| > make
| |
| > sudo make install
| |
| | |
| Make sure that you have all the dependency needed to build this library.

| === Paraview WebService (PWService) ===
| |
| | |
| ==== Introduction ====
| |
| | |
| The goal of this component is to provide an access point for remote
| |
| visualisation such as Web visualisation. Moreover, some administration
| |
| web pages are given to monitor and administrate the running processes.
| |
| The administration pages are protected by a login and a password. This
| |
| authentication login/password can be changed in the configuration file
| |
| of the application. The default values are :
| |
| | |
| login : admin
| |
| password : admin
| |
| | |
| Moreover, the PWService is a Web application that can run on any
| |
| computer without rebuilding it. Therefore, a binary package can be used
| |
| for the distribution regardless the targeted platform.
| |
| | |
| ==== Prerequisites ====
| |
| | |
| ===== Flex SDK 3 or above =====
| |
| | |
| Flex is a web framework developped by Adobe that is used in our
| |
| application for the component that is responsible to show the rendering
| |
| window. In order to compile our component, you will need to download
| |
| the SDK here http://opensource.adobe.com/wiki/display/flexsdk/Downloads.
| |
| | |
| ===== Java 1.6 =====
| |
| | |
| Java will be used as a compiler and a runtime. In order to use it you
| |
| will need to download it at the following url
| |
| http://java.sun.com/javase/downloads/widget/jdk6.jsp
| |
| | |
| ===== Tomcat 6 for the runtime =====
| |
| | |
| Tomcat is a web server used to run Java web application, therefore it
| |
| will only be needed for the deployment and the runtime. You can download
| |
| the application at the following url http://www.proxytracker.com/apache/tomcat/tomcat-6/v6.0.26/bin/apache-tomcat-6.0.26.zip
| |
| | |
| ==== Configuration and building ====
| |
| | |
| The PWService do not require any sample to work, therefore we will
| |
| focusing on building only the core service with all the settings that
| |
| are mandatory. The command line given below are for Unix systems and
| |
| paths are given as example.
| |
| | |
| > mkdir build-pw install-pw <---- Optional if you've done
| |
| > cd build-pw <---- it for ParaviewAdapter

| |
| | |
| ==== Deployment ====
| |
| | |
| The PWService as a Java Web application requires a framework to run,
| |
| you will need to deploy the compiled application into that framework.
| |
| To do so, you can do it automatically with CMake or with the following
| |
| procedure. The CMake procedure can only work if the deployement is done
| |
| on the same computer. More details are given after the general case.
| |
| | |
| General case procedure:
| |
| | |
| * Install tomcat by unzipping it in a directory.
| |
| * Copy the file install-pw/Web-apps/PWService.war into the TOMCAT_ROOT/webapps directory.
| |
| * Copy the file install-pw/Web-apps/pw-config.properties into the TOMCAT_ROOT/lib directory.
| |
| * Eventually edit the TOMCAT_ROOT/lib/pw-config.properties to fix path and settings.
| |
| * You are done ! The application is ready to work and the URL will be http://localhost:8080/PWService
| |
| | |
| To start tomcat:
| |
| > cd TOMCAT_ROOT/bin
| |
| > ./catalina.sh start
| |
| | |
| To stop tomcat:
| |
| > cd TOMCAT_ROOT/bin
| |
| > ./catalina.sh stop
| |
| | |
| CMake automatic deploy:
| |
| | |
| For automatic deployment with CMake, you will have to set the
| |
| following properties in order to use the "make deploy" command.
| |
| | |
| WEB_DEPLOY ON
| |
| TOMCAT_HOME /opt/apache-tomcat-6.0.24
| |
| | |
| Once is done you can simply do:
| |
| > make deploy
| |
| | |

| |
| | |
| == Deployment ==
| |
| | |
| === Prerequisites ===
| |
| | |
| The following software or files should be available on the computer that
| |
| will execute the application
| |
| | |
| * Applications:
| |
| ** Java : JDK 1.6 from sun and NOT the OpenJDK
| |
| ** ActiveMQ : Binary package
| |
| ** Tomcat 6 : Binary package
| |
| | |
| * Builded components:
| |
| ** PWServer : Builded executable with its dependency library. (ParaView, ActiveMQ-CPP, Python)
| |
| ** PWService.war : Web Service for remote visualization
| |
| ** pw-config.properties : Configuration file for the PWService
| |
| | |
| * Optional builded components:
| |
| ** PWApp.war : Complex Web application
| |
| ** PWConsole.war : Javascript command line console sample
| |
| ** PWSandbox.war : Sandbox sample application
| |
| ** PWSimple.war : Simple static Javascript code starting 2 concurrent visualization session with 6 renderer.
| |
| ** Sample Data : Some sample data are provided and used in the PWApp application. To allow the application to find them, you will need to copy the data directory from the source to the WORKING_DIR in order to get a file path like the following one. Beaware of the case ! > WORKING_DIR/data/cow.vtp
| |
| | |
| Tomcat need to be pre-configured in order to run the web components
| |
| properly. To do so, just copy the war file that you want to run into the
| |
| webapps directory of your tomcat.
| |
| Add a configured version of the pw-config.properties into the "lib"
| |
| directory of your tomcat.
| |
| | |
| === Starting the application ===
| |
| | |
| * If an OpenJDK is installed on the computer, you will need to set the JAVA_HOME system property before launching tomcat and the JMS brocker.
| |
| The following command line illustrate how to do it on linux:
| |
| > export JAVA_HOME=/opt/jdk1.6.0_18
| |
| | |
| * Start the JMS brocker
| |
| > cd apache-activemq-5.3.0/bin/
| |
| > ./activemq
| |
| * Start tomcat
| |
| > cd apache-tomcat-6.0.24/bin
| |
| > ./startup.sh
| |
| | |
| To quit the applications
| |
| > CTR-C in the terminal that start the activemq message broker
| |
| > cd apache-tomcat-6.0.24/bin
| |
| > ./shutdown.sh
| |
| | |
| === How to try it ! ===
| |
| | |
| * Make sure that ActiveMQ and Tomcat are running.
| |
| * Go with your browser to the PWService home page.
| |
| ** http://localhost:8080/PWService
| |
| * Try to login (admin/admin)
