#    The compound command "/vis/drawVolume <physical-volume-name>"    #
#    is equivalent to the following set of commands:                  #
#                                                                     #

#    WARNING: You need one more command "/vis/viewer/update" for      #
#             flushing in using post-processin visualization drivers  #
#             such as the DAWNFILE, VRMLFILE, OpenGL Motif drivers.   #
#             You can execute, e.g. "/vis/draw/axes" before executing #
#             "/vis/viewer/update" to visualize coordinate axes.      #
#                                                                     #

# Visualization with DAWNFILE driver
#
#  * Each visualized view is saved to a file "g4_XX.eps"  
#    with the "vectorized" PostScript format.
#
#  * In order to make the file "g4_XX.eps" printable, 
#    append the "showpage" PostScript command to the file. 
#    You can do it with the 4th page of the DAWN GUI panel 
#    or by editing the file by hand.
#
#  * Set an environmental variable if you wish to 
#    skip DAWN GUI:
