PyMOL-Wasm

This is a repository providing a binary and html/javascript code for WebAssembly port of PyMOL.

I've checked latest google chrome and firefox can run this project.

What's PyMOL-Wasm

• This project is based on pymol-open-source. pymol-open-source
• The source code was slightly modified to make it compatible with emscripten and WebGL.
• The modified source code will be available soon in different repository.

License

• The pymol part follows original PyMOL's license: See this
• The frontend part (Javascript and html) follows MIT license.

Demonstration page

• Visit here: Quite a simple demo page

Current Limitation

• Selection by clicking behave slightly different from original PyMOL. Try moving the pointer after clicking.
• Too large structures cannot be loaded.
• The resizing window after launching PyMOL makes the click-position recogntion wrong.
• The dot representation is very weak to see and very heavy to load.
• Trying to show the cell (unit cell) crashes the session.

Dependency and requirements for building

• pymol-open-source
• gl4es
• exodide
• pyodide

How this works

• PyMOL source code was built into whl by emscripten with help of exodide.
• The whl is loaded by Pyodide.
• Pyodide executes pymol commands called by Javascript.
• Javascript controls which pymol commands should be executed.

Feedbacks

• We appreciate your feedbacks to improve this project.

ToDo

• Refinement/refactoring of index.html should be done. It's now quite primitive html/javascript.
• See issues for other ideas.
