NGL Viewer is a web application for molecular visualization. WebGL is employed to display molecules like proteins and DNA/RNA with a variety of representations. Further, a server is included that enables remote access and animation of coordinate trajectories, for instance, from molecular dynamics simulations.

See it in action:

• Web application
• Documentation

Features

• Molecular structures (mmCIF, PDB, GRO, SDF, MOL2)
• Density volumes (MRC/MAP/CCP4)
• User interaction (mouse picking, selection language, image export)
• Coordinate trajectories (animation, server)
• Embeddable (single file, API)

Acknowledgments

This project would not be possible without recourse to many fine open-source projects. Especially the three.js project provides a great foundation. See here for a detailed list of acknowledgments.

Changelog

Version 0.6dev

• CODE: clearer atomnames handling for fiber creation
• FIX: residues at the end of fibers may not require all backbone atoms
• ADD: User-defined color schemes (API)
• CODE: Color handling code refactored exposing more parameters
• FIX: #7
• DOC: pull request instruction for developers
• Higher color contrast for GUI and documentation pages
• CODE: Basic support for async creation of representations (so far used for molecular surfaces and volume triangulation)
• WIP: scripting API
• CODE: chunked data loading and parsing via streamer class
• MIGRATION: Stage.loadFile signature changed
• CODE: faster autobonding of large residues (e.g. hydrated lipids)
• CODE: WebWorker support while using development and build files
• CODE: WebWorker used for decompression, parsing and surface generation
• ADD: Support for MOL2 and SDF files

Version 0.5

The first release.
