VDB_RENDER(1)

NAME
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.
