Ideas for PyMOL Development
This page was originally developed for the 2008 Google Summer of Code competition, but seeing as PyMOL wasn't selected, this page can instead serve as a resource for ongoing PyMOL development efforts.
Where to Start
Always start with Python and only delve down into the C code when absolutely necessary. Although PyMOL is mostly a C-based application, much of the that code is opaque, fragile, and unforgiving. Although C code refactoring is an important project goal, such work may not be ideal since once mistake could potentially to destabilize the entire platform.
Fortunately, the Python interpreter and the PyMOL command and selection languages make it possible to extend PyMOL safely and quickly. Even when performance is critical, Python should be the interface between external C, C++, and Java code and PyMOL's internal C data structures.
Choosing a Topic
The best open-source code is usually written by an end-users attempting to meet their own pressing needs. So if you have already have a specific need which relates to PyMOL, then we strongly encourage you to follow up on that first!
If you are looking for ideas, then try to seek out enhancements and/or integrations that will impact the largest potential user base. For example, imagine what new things might be useful to virtually all medicinal chemists, all structural biologists, all movie-makers, all paper-writers, and so forth.
The ideas below are organized by category. Right now, integration with other open-source projects seems like the approach most likely to yield significant benefit, so those ideas are first.
Integration Ideas (Linking Out to Useful Open-Source Tools)
In most cases, depending on the need, integration can be accomplished through standalone Python scripts, through new PyMOL commands, through PyMOL Wizards, or via Tkinter plugins.
- APBS (electrostatics calculations): Improve the existing plugin. Michael Lerner is currently leading this effort. See APBS
- RDKit (cheminformatics, depiction, UFF cleanup, etc.): Lots of potential here, however C++ coding may be necessary for more advanced integration tasks. RDKit home

- GIMP (image manipulation): Streamline & document the process of exporting images from PyMOL into GIMP and preparing them for submission to scientific Journals.
- yea (0) / nay (0)
- Jmol (publishing visualizations inside of web pages): Liason between PyMOL & Jmol projects to develop a shared molecular visualization data model compatible with both applications.
- yea (0) / nay (0)
- Firefox (plugin): Develop an PyMOL plugin compatible with Firefox.
- yea (Vvostri) / nay (0)
- MMTK (molecular mechanics -- Python/flexible): Develop the ability to round-trip molecular systems from PyMOL, into MMTK, and back.
- yea (0) / nay (0)
- GROMACS (molecular mechanics -- C/fast) - Maybe some ideas can be shared with this guy. Gromacs GUI
- yea (Jedgold) / nay (0)
- OpenOffice (escape Microsoft hegemony): Develop an PyMOL plugin.
- yea (0) / nay (0)
- IPython integration (interactive shell): a robust alternative to the PyMOL command line?
- yea (0) / nay (0)
- R (statistics): PyMOL a 3D viewer environment for visualizating & manipulating large statistical data sets?
Are there other key open-source packages we might specifically target for integration with PyMOL, either through GSoC or beyond?

Difficult C-level Code Refactoring Ideas
- Assemble a test suite which thoroughly exercises the existing code (a prerequisite to major refactoring).

Ideas Involving Proprietary APIs
Since these involve closed-source APIs and infrastructure, they aren't suitable for open-source development efforts. However, such requests are noted here for the sake of complete coverage.
- Create a Windows port with "native" look & feel. <- Could this be done in PyQT or PyGTK?. Then it would look "native", but be cross-platform and not proprietary.

- Integrate directly via Mathematica via MathLink.

More Ideas (Please add your own!)
- MolViz is a project to incorporate head tracking input into PyMol. This is accomplished through a ImmersiveViz script written in Python to control the molecule's position using the existing PyMol API. Related projects would include:
- Improving the existing ImmersiveViz PyMol plugin for more precise control of the environment.
- Developing new input drivers for the Wiimote form of control. This would require some bluetooth hacking.
- Implementing some other forms of input for head tracking, such as fisheye head tracking, IR webcam tracking, etc (refer to the end of this [video] for a better description).
