MOLCAD features
complex scenes
Inspection of big molecules like the capsid of the tobacco ringspot virus with up to 240.000 atoms often needs a combination of visualization techniques. To get a view inside the virus, clipping-planes were applied to the surface, ribbon and the stick representation to cut the appropriate parts of the objects. The inner "glow" is a volume-rendered representation of a 3D-data-field, representing the distance to the molecular surface of the capsid. The distance is coded by different colors and alpha-values. The complete scene can be changed interactively.
