47   .SH DESCRIPTION
48   .I Rhcopy
49 < adds ray sample data to the existing holodeck
28 < .I dest_holo.
49 > typically adds ray sample data to an existing holodeck.
50   In the first form, the ray samples are taken from one or more holodeck files
51   given after the
52   .I \-h
53   option.
54   In the second form, the ray samples are taken from one or more RADIANCE
55 < picture files and their depth buffers, which must be paired on the
56 < command line after the
55 > picture files and their corresponding
56 > depth buffers, which must be paired on the command line after the
57   .I \-p
58   option.
59 + In the third form, ray samples are read from the standard input
60 + based on parameters specified by the
61 + .I \-i
62 + option, which should match (for example) the corresponding
63 + .I \-o
64 + option of an
65 + .I rtrace(1)
66 + command.
67 + Note that a header is not expected on input, and some parameters
68 + are required for correct operation.
69 + A
70 + .I \-f
71 + option may be used to specify raw rather than ASCII data.
72   .PP
73 + The final form reads rays from the given holodeck and writes
74 + them to the standard output according to the
75 + .I \-o
76 + specification.
77 + .PP
78   The
79   .I \-u
80   option turns on duplicate ray checking.

132 + A much less efficient way to copy the same data:
133 + .IP "" .2i
134 + rhcopy old.hdk -oodlv | rhcopy new.hdk -iodlv
135 + .PP
136   To add ray samples from two pictures to the new holodeck:

# Line 104 | Line 147 | program once all runs of
