              @file ... = response file(s) containing command-line arguments

              -i <nin> = input nrrd to render (nrrd)

       -k <kind> = "kind" of volume ("scalar", "vector", or "tensor")
              (kind)

       -fr <eye pos> = camera eye point (3 doubles)

       -at <at pos> = camera look-at point (3 doubles); default: "0 0 0"

       -up <up dir> = camera pseudo-up vector (3 doubles); default: "0 0 1"

              -rh = use a right-handed UVN frame (V points down) -or = orthogonal (not perspective) projection

       -dn <near> = distance to near clipping plane (double)

       -di <image> = distance to image plane (double)

       -df <far> = distance to far clipping plane (double)

              -ar = near, image, and far plane distances are relative to the

              *at* point, instead of the eye point

       -ur <uMin uMax> = range in U direction of image plane (2 doubles);
              default: "nan nan"

       -vr <vMin vMax> = range in V direction of image plane (2 doubles);
              default: "nan nan"

       -fv <field of view> = angle (in degrees) vertically subtended by view window

              (double); default: "20"

              -offfr = the given eye point ("-fr") is to be interpreted as an

              offset from the at point.

       -turn <angle> = angle (degrees) by which to rotate the from point around
              true  up,  for  making  stereo pairs. Positive means move towards positive U (the right) (double);
              default: "0.0"

       -is <image size> = image dimensions (2 ints); default: "256 256"

       -k00 <kernel> = value reconstruction kernel (kernel specification);
              default: "tent"

       -k11 <kernel> = first derivative kernel (kernel specification);
              default: "cubicd:1,0"

       -k22 <kernel> = second derivative kernel (kernel specification);
              default: "cubicdd:1,0"

              -rn = renormalize kernel weights at each new sample location.

              "Accurate" kernels don't need this; doing it always makes things go slower

       -q <query> = the quantity (scalar, vector, or matrix) to learn by
              probing (string)

       -m <measure> = how to collapse list of ray samples into one scalar.
              Possibilities  include: o   "min",   "max",   "mean",   "median",   "mode",   "variance",   "skew"
              (self-explanatory)o  "intc", "slope", "error": intercept, slope, and error from line fittino "sd":
              standard deviatioo "product", "sum": product or sum of all valueo "L1",  "L2",  "Linf":  different
              normso  "histo-min",  "histo-max",  "histo-mean",  "histo-median",  "histo-mode", "histo-product",
              "histo-l2", "histo-sum", "histo-variance", "histo-sd": same measures,  but  for  situations  where
              we're given not the original values, but a histogram of them.  (measure)

       -gmc <min gradmag> = For curvature-related queries, set answer to zero when
              gradient magnitude is below this (double); default: "0.0"

       -fn <from nan> = When histo-based measures generate NaN answers, the
              value that should be substituted for NaN. (double); default: "nan"

       -step <size> = step size along ray in world space (double);
              default: "0.01"

       -nt <# threads> = number of threads hoover should use (int); default: "1"

       -vp <img coords> = pixel coordinates for which to turn on all verbose
              debugging messages, or "-1 -1" to disable this. (2 ints); default: "-1 -1"

       -o <filename> = file to write output nrrd to. Defaults to stdout ("-").
              (string); default: "-"

DESCRIPTION

       Uses  hoover  to  cast  rays through a volume (scalar, vector, or tensor), gage to measure one of various
       quantities along the rays, and a specified nrrd measure to reduce all the values along a ray down to  one
       scalar, which is saved in the output (double) image.
