Introduction

Glance is an open-source, javascript visualization application created by Kitware, based on Visualization Toolkit (VTK), and intended to serve as a light-weight companion to Paraview. It is part of the ParaView Web suite of tools.

Learning Resources

• General information is available at the ParaView and ParaView Web homepages.

• Community discussion takes place on the ParaView Discourse.

• Commercial support and training are available from Kitware.

• Additional documentation is being created and will be released as it is created on our documentation pages.

Building

The prerequisites are git and node.js + npm.

If you wish to view, enhance, or adapt this application in any way, you can access and run the freely available source code from any platform using the following commands:

$ git clone https://github.com/Kitware/glance.git
$ cd glance/
$ npm install
$ npm run build
$ npm run dev

This will run a development build and you can visit the application at http://localhost:9999.

Deploying to Production

To generate a production build, use the following commands:

$ npm run build:release

This will output the final bundle and assets to dist/. You can then recursively copy all of those files into the web location of your choice. As there is no server-side code involved, all you need is some web hosting!

If you make changes to any of the ITK filtering code under itk/, you should run the following command from the root folder. For more information, check out itk.js.

$ npx itk-js build itk/

Building as a standalone file

ParaView can use Glance for scene exports. To generate a standalone HTML file embedding Glance to use with ParaView, you can run:

$ npm run build:inline

This will generate a self-contained dist/ParaViewGlance.html file that you can directly use as a template in ParaView VTKJS scene export.
