Haptic devices in molecular modelling
Complex Systems Simulation Seminar Series (CS^4)
from the Institute for Complex Systems Simulation, the Complexity in Real-World Contexts USRG, the Computational Modelling Group and the Computational Systems Chemistry section (School of Chemistry).
Abstract
Studying macromolecular assemblies interactively is becoming an increasingly appealing approach to molecular modeling [1]. Interactive simulations are precious in exploring and generating hypotheses. They introduce a human factor and benefit from the user's experience and insight. By using a 3D haptic device, molecules can be manipulated with great precision and interactions can be felt by the user in real time via tactile feedback.
With a focus on interactive approaches to study macromolecular structure, flexibility and interactions, I will describe several investigations of enzymatic systems and membrane proteins. In this context, visualisation can be another limiting factor, and I will illustrate the possibilities offered by novel GPU implementations of molecular structure depiction with methods such as shader-based ray-casting [2].
