The plots can be easily made interactive and allow for manipulation, which could be an efficient tool for examining a distribution and finding the optimal rendering technique. Demo programs, available in the distribution, show how the routines can be used to create 3D plots, manipulate them via keys or with a mouse, and create sequences of frames that can be used to create a movie showing the 3D distribution in motion. The distribution is available for download as gzipped-tarred archive p3d.tar.gz . If you download the code, please register by sending me an e-email , so you can be notified promptly about changes and additions. Use for any other purposes requires special arrangements.
Particles are color-coded with local density at the position of the particle.
