       vdb_render - ray-traces OpenVDB volumes

SYNOPSIS

       vdb_render in.vdb out.{exr,ppm} [options]

DESCRIPTION

       Which: ray-traces OpenVDB volumes Options:

       -aperture F
              perspective camera aperture in mm (default: 41.2)

       -camera S
              camera type; either "persp[ective]" or "ortho[graphic]" (default: perspective)

       -compression S
              EXR compression scheme; either "none" (uncompressed), "rle" or "zip" (default: zip)

       -cpus N
              number  of  rendering threads, or 1 to disable threading, or 0 to use all available
              CPUs (default: 0)

       -far F camera far plane depth (default: inf)

       -focal F
              perspective camera focal length in mm (default: 50)

       -fov F perspective camera field of view in degrees (default: 44.8)

       -frame F
              ortho camera frame width in world units (default: 1)

       -lookat X,Y,Z
              rotate the camera to point to (X, Y, Z)

       -name S
              name of the grid to be rendered (default:  render  the  first  floating-point  grid
              found in in.vdb)

       -near F
              camera near plane depth (default: 0.001)

       -res WxH
              image dimensions in pixels (default: 1920x1080)

       -r X,Y,Z

       -rotate X,Y,Z
              camera rotation in degrees (default: look at the center of the grid)

       -shader S
              shader name; either "diffuse", "matte" or "normal" (default: diffuse)

       -samples N
              number of samples (rays) per pixel (default: 1)

       -t X,Y,Z

       -translate X,Y,Z
              camera translation

       -up X,Y,Z
              vector that should point up after rotation with -lookat (default: [0, 1, 0])

       -v     verbose (print timing and diagnostics)

       -h, -help
              print this usage message and exit

   Example:
              vdb_render crawler.vdb crawler.exr -shader diffuse -res 1920x1080 \

       -focal 35 -samples 4 -translate 0,210.5,400 -compression rle -v

       This is not (and is not intended to be) a production-quality renderer, and it is currently
       limited to rendering level set volumes.
