OHIF VTK Plugin

Usage

OHIF Plugin for The Visualization Toolkit (VTK)

1. Load the OHIF Viewer on a study
2. Paste the following into your JavaScript console to define the plugin and load the scripts.

var plugin = {
    name: "VolumeRenderingPlugin",
    url: "https://cdn.rawgit.com/OHIF/VTKPlugin/master/volumeRendering/main.js",
    allowCaching: false,
    moduleURLs: [
    	"https://cdn.rawgit.com/OHIF/VTKPlugin/master/lib/index.js",
    ],
    scriptURLs: [
        'https://unpkg.com/vtk.js',
    ]
};
OHIF.plugins.OHIFPlugin.reloadPlugin(plugin);

3. Switch a viewport to use the plugin by specifying its viewport index:

OHIF.plugins.VolumeRenderingPlugin.setViewportToPlugin(0)

Development

This will install a local copy of the OHIFViewer and let you run a server that can be used for plugin development.

You will get:

• a local scratch copy of the OHIF StandaloneViewer running on port 3000
• a web server to serve your plugin code on port 8000
• sample data from the links below will be pulled from public data stored on Amazon S3

Prerequisites

• Run on a linux/mac environment with bash (windows not supported or tested)
• All the things needed to build OHIFViewers
• http-server

1. Create a copy of the OHIF Standalone Viewer Meteor app (i.e. not built into a static site yet)

./setupDevSite.sh

2. Install an HTTP server which supports CORS:

# If you get some EACCESS errors, use sudo.
npm install http-server -g

3. Start the HTTP server with CORS enabled

• You will see some logs in your console whenever requests reach your server at http://localhost:8000
• This serves the plugin directory itself, so any changes you make to the plugin are instantly available.

http-server -p 8000 --cors

4. Open another terminal tab and start the Standalone Viewer.

./startDevSite.sh

• This version of the StandaloneViewer has some scripts copied into it which enable the MultiplanarReformatting and VolumeRendering plugins by default.
• Note: If you change anything in these scripts, you will need to run setupDevSite.sh again.

5. Test the installation by loading one of the following URLs:

• PTCTStudy
• CTStudy
• MRStudy
