Example 1 with Switch

use of javax.media.j3d.Switch in project ffx by mjschnie.

the class MolecularAssembly method createScene.

/**
 * The MolecularAssembly BranchGroup has two TransformGroups between it and
 * the "base" node where geometry is attached. If the point between the two
 * transformations is where user rotation occurs. For example, if rotating
 * about the center of mass of the system, the RotToCOM transformation will
 * be an identity transformation (ie. none). If rotation is about some atom
 * or group of atoms within the system, then the RotToCOM transformation
 * will be a translation from that point to the COM.
 *
 * @param zero boolean
 * @return BranchGroup
