YASARA View—molecular graphics for all devices—from smartphones to workstations

Advance Access publication July 4, 2014 | Elmar Krieger and Gert Vriend
The article introduces YASARA View, a molecular modeling program designed to visualize molecular structures on various devices, from smartphones to workstations. The authors address the challenge of rendering large proteins with atomic details, which requires tens of millions of triangles, leading to slow interactive frame rates. They propose a new approach that shares the workload between GPUs and multiple CPU cores, generating high-quality results with perfectly round spheres, shadows, and ambient lighting. This method only requires OpenGL 1.0 functionality and does not need pixel shader Z-buffer access, making it suitable for mobile devices. The program is freely available for Linux, Mac OS, Windows, and Android (Intel). The article also discusses the limitations of the method, such as restricted atom colors and sizes, and provides performance metrics for different devices.The article introduces YASARA View, a molecular modeling program designed to visualize molecular structures on various devices, from smartphones to workstations.
