              @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-explanatoryo "intc", "slope", "error": intercept, slope, and error from  line
              fittingo  "sd":  standard  deviatioo "product", "sum": product or sum of all valueo

              "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.
