and analysis of molecular
structures, density maps, 3D microscopy, and associated data. It addresses challenges
in the size, scope, and disparate types of data attendant with cutting‐edge experimental
methods, while providing advanced options for high‐quality rendering (interactive
ambient occlusion, reliable molecular surface calculations, etc.) and professional
approaches to software design and distribution. This article highlights some specific
advances in the areas of visualization and usability, performance, and extensibility.
