New issue 1192: Rotating function for datasets http://link.bitbucket.org/wf/click?upn=8USRlNyft-2BCzk2l4Ywl6gDx2lD2xxoS9E7M... Anonymous: I would like to request a feature that allows for an arbitrary rotation in 3D around a chosen origin, for all particles in a loaded HDF5 dataset: e.g. ds_rotated = yt.rotate(ds,[x_angle,y_angle,z_angle],origin) (The example above should change the positions and velocities of particles in 'ds' and save in a new dataset called ds_rotated) Thanks, Karen
