We show that a rotation in three dimensions can be achieved by a composition of three shears, the rst and third along a speciied axis and the second along another given axis orthogonal to the rst; this process is invertible. The resulting rotation algorithm is practical for the processing of ne-grained digital images, and is well adapted to the access(More)
A new approach to polymer simulation well suited to massively parallel architectures is presented. The approach is based on a novel two-space algorithm that enables 50% of the monomers to be updated in parallel. The simplicity of this algorithm enables implementation and comparison of different platforms. Such comparisons are relevant to a wide variety of(More)
