3D Recipe: Drug Design Meets Virtual Reality
I still remember the distinct sense of wonder upon seeing the first immersive chemistry visualization environments in pharmaceutical companies' hiring brochures. These culminated in CAVEs*, where groups of scientists could congregate, done special glasses, and be surrounded by room-size, manipulable molecules. Now, the promise of bringing virtual reality to every bench chemist seems a little closer, thanks to the Molecular Rift.
In last week's ASAP issue of the Journal of Chemical Information and Modeling, a team of researchers from Lund University (Sweden) and AstraZeneca teamed up to deliver a relatively inexpensive ($500) virtual reality setup based on the Oculus Rift, a VR headset, paired with the Microsoft Kinect, a motion sensor popularly used with the Xbox. The paper prescribes a collage of open-source software - including the video game engine Unity and the chemistry informatics package Open Babel - that the Swedish researchers utilize to model metal complexes and a CB1 receptor, complete with undulating ribbons of secondary structure.
So, what's the big advance here? It's all in the control: the Kinect sensor watches the user's hands, allowing navigation of the molecular model using intuitive hand gestures. This way, the chemist doesn't have to intrude on the immersive VR with keyboards, joysticks, or mouse clicks.
Hoping to "...stimulate further development in a collaborative fashion," the authors have released the source code to the public** through the open-source code repository GitHub. If you're among the first to try it out, drop me a line!
