Molecular visualization and manipulation can be costly computational wise, especially for proteins, as it oftentimes deals with a large quantity of atomic data. We have found that for mobile platform surface model generation and rendering of a protein takes approximately 5 to 6 times more duration to complete than for the desktop version. Plus, virtual reality display, compared to conventional 2D display, is innately more expensive due to its requirement from hardware to render an image twice, one for the left eye and the other for the right eye. To combat the above limitation and to improve the overall user experience, we have been looking into optimizing the program via multi-threading processing and GPU processing. Also, as MINT is built using Unity3D game engine, Unity's recent engine update in 2018, which improves its support for developers to build a high-performance application, will contribute to the optimization of MINT as well.
