 LAMMPS snapshots are created by the "dump"_dump.html command which can

 Several programs included with LAMMPS as auxiliary tools can convert

+lammps2pdb Perl script which converts LAMMPS dump files into PDB
+files.  The second is the "lmp2arc tool"_Section_tools.html#arc which
+converts LAMMPS dump files into Accelrys' Insight MD program files.
+The third is the "lmp2cfg tool"_Section_tools.html#cfg which converts

 A Python-based toolkit distributed by our group can read native LAMMPS
 dump files, including custom dump files with additional columns of
 user-specified atom information, and convert them to various formats
 or pipe them into visualization software directly.  See the "Pizza.py
-WWW site"_pizza for details.

-LAMMPS can create a selection of file formats natively (via "dump"_dump.html)

-"pre-/post-processing tools"_http://lammps.sandia.gov/prepost.html

-In addition LAMMPS also includes a small render library to create

-(via "dump image"_dump_image.html) or automatically convert

+LAMMPS dump files into PDB, XYZ, "Ensight"_ensight, and VTK formats.
+Pizza.py can pipe LAMMPS dump files directly into the Raster3d and
+RasMol visualization programs.  Pizza.py has tools that do interactive
+3d OpenGL visualization and one that creates SVG images of dump file
+snapshots.
+
+LAMMPS can create XYZ files directly (via "dump xyz") which is a
+simple text-based file format used by many visualization programs
+including "VMD"_vmd.
+
+LAMMPS can create DCD files directly (via "dump dcd") which can be
+read by "VMD"_vmd in conjunction with a CHARMM PSF file.  Using this
+form of output avoids the need to convert LAMMPS snapshots to PDB
+files.  See the "dump"_dump.html command for more information on DCD
+files.
+
+LAMMPS can create XTC files directly (via "dump xtc") which is GROMACS
+file format which can also be read by "VMD"_vmd for visualization.
+See the "dump"_dump.html command for more information on XTC files.
