BrainBrowser is a JavaScript library allowing for web-based, 2D and 3D visualization of neurological data. It consists of the Surface Viewer, a real-time 3D rendering tool for visualizing surface data, and the Volume Viewer, a slice-by-slice volumetric data analysis tool.

BrainBrowser uses open web-standard technologies such as HTML5, CSS, JavaScript and WebGL. The Surface Viewer uses three.js for 3D rendering.

Demonstrations of available functionality can be found at the BrainBrowser website.

Getting Started

To try out some BrainBrowser sample applications, simply clone this git repo, and make the examples directory available over HTTP. This can be done using nano-server:

  $ git clone https://github.com/aces/brainbrowser.git
  $ npm install -g nano-server
  $ nano-server 5000 brainbrowser/examples

Note that nano-server is recommended because it can send gzip compressed versions of requested files. If a server without this functionality is used, files in brainbrowser/examples/models/ and brainbrowser/examples/color-maps/ will have to be gunzipped.

Once the server is running, navigate to to appropriate address (localhost:5000 in the above example) in your browser and select either of the Surface Viewer or Volume Viewer sample applications.

Surface Viewer

The BrainBrowser Surface Viewer allows users to display and manipulate 3D surface data. The Surface Viewer is invoked by calling BrainBrowser.SurfaceViewer.start() with the id of the HTML element into which the viewer will be inserted, and a callback function to which a viewer object will be passed:

  BrainBrowser.SurfaceViewer.start("viewer-div", function(viewer) {
    // Manipulate viewer object here.
  });

Full documentation of the Surface Viewer API can be found here.

Volume Viewer

The BrainBrowser Volume Viewer allows users to display and manipulate volumetric data in a slice-by-slice manner. The Volume Viewer is invoked by calling BrainBrowser.VolumeViewer.start() with the id of the HTML element into which the viewer will be inserted, and a callback function to which a viewer object will be passed:

  BrainBrowser.VolumeViewer.start("viewer-div", function(viewer) {
    // Manipulate viewer object here.
  });

Full documentation of the Volume Viewer API can be found here.
