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

Avivator A lightweight viewer for local and remote datasets. The source code is include in this repository under avivator/. See our 🎥 video tutorial to learn more. |

Vizarr A minimal, purely client-side program for viewing OME-NGFF and other Zarr-based images. Vizarr supports a Python backend using the imjoy-rpc, allowing it to not only function as a standalone application but also directly embed in Jupyter or Google Colab Notebooks. |

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.
$ npm install @hms-dbmi/vivYou 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/coreBreaking changes may happen on the minor version update. Please see the changelog for information.
Detailed API information and example sippets can be found in our documentation.
This repo is a monorepo using pnpm workspaces. The package manager used to install and link dependncies must be pnpm.
Each folder under packages/ are a published as a separate packages on npm under the @vivjs scope. The top-level package @hms-dbmi/viv exports from these dependencies.
To develop and test the @hms-dbmi/viv package:
- Run
pnpm installinvivroot folder - Run
pnpm devto start a development server - Run
pnpm testto run all tests (or specificpnpm test --filter=@vivjs/layers
To build viv's documentation and the Avivator website (under sites/), run:
pnpm build # all packages, avivator, and documentation
pnpm -r build --filter=avivator # build a specific package or siteCheckout latest master branch, run:
# checkout a new release branch
git checkout <branch name>
# commit and tag a new version
pnpm version [major | minor | patch]
# push commit and tag simultaneously
git push --atomic origin <branch name> <tag>Open a PR for <branch name>. Our CI will run a release workflow for tagged commits starting
with v* automatically. Inspect the GitHub Actions to ensure the workflow was successful.
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.
