**What is P3D?** P3D is a collection of simple but efficient
fortran 77 routines,
which can be used with the
PGPLOT graphics library to plot three-dimensional particle distributions.
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 programs are available for download as gzipped-tarred archive p3d.tar.gz.

An example of output generated using the P3D routines: 3D view of the formation of structures in a simulation of CDM model with cosmological constant. The size of shown box is 30/h Mpc. 10% of the total number of particles (2,097,152) is shown. Particles are color-coded with local density at the position of the particle. Click in the image to get a still view of the final state (z=0.0). An example of a short fly-by movie made using P3D routines is available here (MPEG, 1.7Mb). |
