NAMEr3.mkdspf - Creates a display file from an existing 3D raster map according to specified threshold levels.KEYWORDSraster3d, display, voxelSYNOPSISr3.mkdspfr3.mkdspf --help r3.mkdspf [-qf] input=string dspf=name [levels=float[,float,...]] [min=float] [max=float] [step=float] [tnum=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui] Flags:
Parameters:
DESCRIPTIONCreates a display file from an existing grid3 file according to specified threshold levels. The display file is a display list of polygons that represent isosurfaces of the data volume. If specific levels are given, additional optional parameters are ignored. Min or max may be used alone or together to specify a sub-range of the data. The step parameter is given precedence over tnum.Flags:
Parameters:
Example:With grid3 data (phdata) in the range 3-7, we only want to see isosurface values for the range 4-6. Any of these commands will produce the same results:r3.mkdspf phdata dspf=iso min=4.0 max=6.0 tnum=5 r3.mkdspf phdata dspf=iso levels=4.0,4.5,5.0,5.5,6.0 r3.mkdspf phdata dspf=iso min=4.0 max=6.0 step=0.5 NOTECurrently the grid3 file must be in the user’s mapset since the display files being created are specific to particular grid3 files and are contained in directories under them. We should create a mechanism where users may make display files from others’ grid3 files without having to copy them to their mapset.AUTHORBill Brown, bbrown@gis.uiuc.eduSOURCE CODEAvailable at: r3.mkdspf source code (history)Main index | 3D raster index | Topics index | Keywords index | Graphical index | Full index © 2003-2021 GRASS Development Team, GRASS GIS 7.8.6 Reference Manual
