Viv

A WebGL-powered toolkit for interactive visualization of high-resolution, multiplexed bioimaging datasets.

About

Viv is a JavaScript library for rendering OME-TIFF and OME-NGFF (Zarr) directly in the browser. The rendering components of Viv are packaged as deck.gl layers, making it easy to compose with existing layers to create rich interactive visualizations.

💾 Supported Data Formats

Viv's data loaders support OME-NGFF (Zarr), OME-TIFF, and Indexed OME-TIFF*. We recommend converting proprietrary file formats to open standard formats via the bioformats2raw + raw2ometiff pipeline. Non-pyramidal datasets are also supported provided the individual texture can be uploaded to the GPU (< 4096 x 4096 in pixel size).

Please see the tutorial for more information.

*We describe Indexed OME-TIFF in our paper as an optional enhancement to provide efficient random chunk access for OME-TIFF. Our approach substantially improves chunk load times for OME-TIFF datasets with large Z, C, or T dimensions that otherwise may incur long latencies due to seeking. More information on generating an IFD index (JSON) can be found in our tutorial or documentation.

💽 Installation

$ npm install @hms-dbmi/viv

You will also need to install deck.gl and other peerDependencies manually. This step prevent users from installing multiple versions of deck.gl in their projects.

$ npm install deck.gl @luma.gl/core

Breaking changes may happen on the minor version update. Please see the changelog for information.

📖 Documentation

Detailed API information and example sippets can be found in our documentation.

🏗️ Development

$ git clone https://github.com/hms-dbmi/viv.git
$ cd viv && npm install
$ npm start

Please install the Prettier plug-in for your preferred editor. Badly formatted code will fail in our CI.

To run unit and integration tests locally, use npm test. Our full production test suite, including linting and formatting, is run via npm run test:prod.

To our knowledge, Viv can be developed with Node version greater than 10. You can check which current versions are tested in our CI by naviating to our Github Workflow.

🛠️ Build

• @hms-dbmi/viv library: npm run build
• Avivator viewer: npm run build:avivator

📄 Publish

First checkout a new branch like release/version. Update the CHANGELOG.md and bump the version via npm verion [major | minor | patch]. Commit locally and push a tag to Github. Next, run ./publish.sh to release the package on npm and publish Avivator. Finally, make a PR for release/version and squash + merge into master.

🌎 Browser Support

Viv supports both WebGL1 and WebGL2 contexts, to provides coverage across Safari, Firefox, Chrome, and Edge. Please file an issue if you find a browser in which Viv does not work.
