54 max=float
55 Maximum isosurface level
56
57 step=float
58 Positive increment between isosurface levels

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

98 tnum
99 Number of isosurface threshold levels
100 Default: 7

103 Currently the grid3 file must be in the user’s mapset since the display
104 files being created are specific to particular grid3 files and are con‐
105 tained in directories under them. We should create a mechanism where
106 users may make display files from others’ grid3 files without having to
107 copy them to their mapset.
108
110 With grid3 data (phdata) in the range 3-7, we only want to see isosur‐
111 face values for the range 4-6. Any of these commands will produce the
112 same results:
113 r3.mkdspf phdata dspf=iso min=4.0 max=6.0 tnum=5
114 r3.mkdspf phdata dspf=iso levels=4.0,4.5,5.0,5.5,6.0
115 r3.mkdspf phdata dspf=iso min=4.0 max=6.0 step=0.5
