NAME

       vdb_print - generates a volume mipmap from an OpenVDB grid

SYNOPSIS

       vdb_lod in.vdb out.vdb -range FROM[-TO[:STEP]] [options]

DESCRIPTION

       Which: generates a volume mipmap from an OpenVDB grid Where:

       FROM   is the highest-resolution mip level to be generated

       TO     is the lowest-resolution mip level to be generated (default: FROM)

       STEP   is the mip level step size (default: 1)

OPTIONS

       -name S[,S,S,...]
              name(s)  of  the  grid(s)  to be processed (default: process all grids of supported
              types)

       -keep  pass through grids that were not processed (default: discard grids  that  were  not
              processed)

       -nokeep
              cancel an earlier -keep option

       -p, -preserve
              if  only  one  mip  level  is generated, give it the same name as the original grid
              (default: name each level "NAME_level_N", where NAME is the original grid name  and
              N is the level number, e.g., "density_level_0")

       -nopreserve
              cancel an earlier -p or -preserve option

       -version
              print version information

       Mip  level  0  is the input grid.  Each successive integer level is half the resolution of
       the previous level.  Fractional levels are supported.

EXAMPLES

              Generate levels 0,  1,  and  2  (full  resolution,  half  resolution,  and  quarter
              resolution,  respectively)  for  all  grids of supported types and ignore all other
              grids:

              vdb_lod in.vdb out.vdb -range 0-2

              Generate levels 0, 0.5, and 1 for all grids of supported types and pass through all
              other grids:

              vdb_lod in.vdb out.vdb -range 0-1:0.5 -keep

              Generate level 3 for the first of multiple grids named "density":

              vdb_lod in.vdb out.vdb -range 3 -name 'density[0]'

              Generate  level 1.5 for the second of multiple unnamed grids and for the grid named
              "velocity" and give the resulting grids the same names as the original grids:

              vdb_lod in.vdb out.vdb -range 1.5 -name '[1],velocity' -p
