Multi-scale Visualization of Molecular Architecture Using Real-Time Ambient Occlusion in Sculptor

By adding global "ambient occlusion" illumination to a scene, large macromolecular systems look much more natural. Wahle and Wriggers (pcbi.1004516) introduce a novel size-specificity of the shaded features in the Sculptor molecular graphics and modeling software). Shown is a composite of CCMV images (PDB ID 1CWP) with three different scale settings. The illumination can be tuned in real time for pockets and cavities of a user-defined size, making it useful for visualizing large biomolecular systems, comprising e.g. hundreds of thousands of atoms or Mega-Dalton size electron microscopy maps. Wahle et al.
