46 Creates a display file from an existing grid3 file according to speci‐
47 fied threshold levels. The display file is a display list of polygons
48 that represent isosurfaces of the data volume. If specific levels are
49 given, additional optional parameters are ignored. Min or max may be
50 used alone or together to specify a sub-range of the data. The step
51 parameter is given precedence over tnum.

58 Parameters:
59 grid3 Name of an existing 3dcell map
60
61 dspf Name of output display file
62
63 levels List of thresholds for isosurfaces
64
65 min Minimum isosurface level
66
67 max Maximum isosurface level
68
69 step Positive increment between isosurface levels
70
71 tnum Number of isosurface threshold levels Default: 7

74 With grid3 data (phdata) in the range 3-7, we only want to see isosur‐
75 face values for the range 4-6. Any of these commands will produce the
76 same results:
77
78 r3.mkdspf phdata dspf=iso min=4.0 max=6.0 tnum=5
79 r3.mkdspf phdata dspf=iso levels=4.0,4.5,5.0,5.5,6.0
80 r3.mkdspf phdata dspf=iso min=4.0 max=6.0 step=0.5
81
82
84 Currently the grid3 file must be in the user's mapset since the display
85 files being created are specific to particular grid3 files and are con‐
86 tained in directories under them. We should create a mechanism where
87 users may make display files from others' grid3 files without having to
88 copy them to their mapset.
