Class SphereSampler

java.lang.Object
org.biojava.nbio.structure.symmetry.geometry.SphereSampler
public final class SphereSampler extends Object
Sample possible orientations. An orientation can be represented as a quaternion or as a rotation axis and angle. The orientations are somewhat evenly distributed over orientation space, but the current implementation is not suited for statistically uniform sampling.
