Solution Overview

Miew is a high performance web tool for advanced visualization and manipulation of molecular structures.

Molecular modeling software Miew provides a full-featured set of tools for 3D visualization and editing of small molecules as well as large molecular complexes, including means to view, analyze, and modify the 3D structure of a molecule.

It works as a standalone web application or integrates as a component into your web pages. The latest versions of WebGL-enabled desktop (Chrome, Firefox, Safari, Edge) and mobile (iOS, Android) browsers are supported.

v.0.11.0

Updated on Aug 26, 2024

Release Notes

Added

Add a
miew-react
package that contains a React.js wrapper component. It is published as a separate miew-react package on npm.
Add a
miew-app
package with a new demo application code. The goal is to rewrite the old monolith plain JavaScript demo in modular React.js

Changed

Support shadows in sprite-based modes (Licorice, Balls and Sticks, VDW, and Trace).
Clip sprites with near plane instead of culling them.
Color residue names in the "sequence" example according to the secondary structure.
Use CIF format in the demo and examples instead of discontinued MMTF.
BREAKING CHANGE: Bump tree.js to r153. Can break your code only if you rely on specific three.js API yourself.

Removed

BREAKING CHANGE: Remove support for
```
mmtf:
```
prefix during loading because the format is discontinued and files are not served anymore. Parsing local files or specific URLs is still supported.
BREAKING CHANGE: The
```
miew
```
library no longer intercepts the
```
S
```
key. Numpad plus and minus are still processed but require the
```
Alt
```
key pressed to avoid conflicts. The keys will likely be removed in the future versions in favor of event handlers and API calls.

Fixed

Don't crash on
```
addEventListener
```
call if embedded in a cross-origin IFRAME.
Create empty molecules correctly.
Fix
```
HydrophobicityColorer
```
behavior.
Rebuild the geometry after enabling or disabling
```
zSprite
```
setting.
Change event name in the docs:
```
rebuildingDone
```
to
```
buildingDone
```
.
Fix "sequence" example to use the proper event.

Internal

Use the
```
main
```
branch as the main instead of the abandoned
```
master
```
.
Reorganize the project as a monorepo.
Migrate to Yarn 3.
Migrate to GitHub Actions for CI builds instead if TravisCI.
Migrate to Webpack instead of Rollup for building the library.
Remove IDE files from the repository.
Support the current Node LTS 18 and 20 for development.
Create a Dockerfile for building an image.
Convert several remaining old-style JS files to ES2015 classes.
Update babel and eslint configurations and fix issues.
Add more tests.
Regenerate golden images.
Translate help document for beginners into English.

v.0.8.1

Updated on Jul 1, 2019

Release Notes

Do not show the last pick information when selection was changed via the terminal.
Update the selection notification when the displayed unit changes.
Fix backdrop material so it works for sprite-based modes (B&S, VDW...).
Fix a bug in Cartoon geometry which led to bad raycasting performance.

v.0.8.0

Updated on Jun 7, 2019

Release Notes

Add iso-surface rendering for electron density maps. As volumetric rendering is still in its alpha, it is done through a global modes.VD.isoMode flag.
Show detailed messages for WebGL initialization errors.
Remove deprecated methods and APIs - BREAKING CHANGES!
Fix the crash on clicking mode/color panel when representation list is empty.
Fix DISTORTED and ANAGLYPH stereo modes.
Fix incorrect shadows when molecule is moved around.
Fix axes disappearing when fxaa is off and ao is on.
Fix rendering issues for fxaa + outline + stereo=DISTORTED.
Fix selection information update when the terminal was used to change selection.
Fix raycasting performance partially. Another fix is still in progress.

v.0.7.24

Updated on May 7, 2019

Release Notes

Add wire frames for electron density volumes.
Fix unrol_loop warning during shader compilation.
Use shadow.on setting to initialize shadowing state.
Build geometry with sharper edges for cartoon sheets and helices.
Reset view interpolator on file load, pause it when miew is paused.

v.0.7.23

Updated on Apr 5, 2019

Release Notes

Support dsn6 prefix for ED maps loading by PDB ID.
Support non-orthogonal density volumes.
Host full-screen viewer at a /v server path and add a button to launch the app from the lite viewer.
Add an interactive example showing residue sequences.
Use https protocol for data requests.
Implement soft shadow edges, make the colors more natural and reduce self-shadowing artifacts.
Use URL options in the corresponding example.
Add titles to the examples.
Fix excessive rendering in case if nothing changes.
Fix disappearing molecule after reloading the page.
Fix full geometry rebuild when switching shadows on/off.
Fix low performance of volumetric rendering in the case when a molecule is present in the scene.

v.0.7.22

Updated on Feb 28, 2019

Release Notes

Make "fullscreen.html" example really full-screen both for desktops and mobiles.
Add experimental sigma-coloring of volumetric maps.
Fix background transparency of the terminal.
Add a temporary workaround for jquery.terminal freeze: don't print square brackets into the term, replace them with parentheses (jcubic/jquery.terminal#470).
Fix rendering conflicts when ssao=true and fxaa=false at the same time.

v.0.7.21

Updated on Feb 14, 2019

Release Notes

Add parsers for MOL, SDF and XYZ molecular formats and MAP, MRC and DSN6 electron density maps.
Add experimental PDB export via miew.save() API.
Molecular geometry can cast shadows now (off by default). The effect still needs additional effort to improve the picture and support sprite-based display modes.
Fix the crash due to zero voxel grid size for very small molecules.
Fix materials and shaders (pre-pass transparency and the backdrop material).
Fix electron density maps rendering: now the threshold is set automatically using the standard deviation stored in a file or calculated over the data. Color of the density map is set to grayscale until further changes to the rendering code are made.
