vdb_print - generates a volume mipmap from an OpenVDB grid
vdb_lod in.vdb out.vdb -range FROM[-TO[:STEP]] [options]
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)
-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.
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' 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 ',velocity' -p
