@file ... = response file(s) containing command-line arguments -i <nsin> = input scalar volume to render (nrrd); default: "" -vi <nvin> = input vector volume to render (nrrd); default: "" -ti <ntin> = input tensor volume to render (nrrd); default: "" -txf <nin ...> = one or more transfer functions (1 or more nrrds) -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) -vr <vMin vMax> = range in V direction of image plane (2 doubles)
-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.
-ffr <fake from> = eye point to use for view-dependent transfer functions.
By default (not using this option), the point used is the normally specified camera eye point. (3 doubles)
-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" -am <ambient> = ambient light color (3 floats); default: "1 1 1"
-ld <light pos> = view space light position (extended to infinity)
(3 floats); default: "0 0 -1" -is <image size> = image dimensions (2 ints); default: "256 256"
-iss <scale> = scaling of image size (from "is") (float);
default: "1.0" -ads <ka kd ks> = phong components (3 floats); default: "0.1 0.6 0.3" -sp <spec pow> = phong specular power (double); default: "30"
-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"
-ss <shading spec> = how to do shading (string);
default: "phong:gage(scalar:n)"
-ns <normal spec> = "normal" to use for those miteVal's that need one
(string); default: ""
o "1": normal points to lower values (higher == more "inside") o "0": "two-sided": dot-products are abs()'d o "-1": normal points to higher values (lower == more "inside") (int) default: "1"
-rn = renormalize kernel weights at each new sample location.
"Accurate" kernels don't need this; doing it always makes things go slower
-gmc <min gradmag> = For curvature-based transfer functions, set curvature to
zero when gradient magnitude is below this (double); default: "0.0"
-step <size> = step size along ray in world space (double);
default: "0.01"
-ref <size> = "reference" step size (world space) for doing opacity
correction in compositing (double); default: "0.01"
-vp <verbose pixel> = pixel for which to turn on verbose messages (2 ints);
default: "-1 -1"
-n1 <near1> = opacity close enough to 1.0 to terminate ray (double);
default: "0.99" -nt <# threads> = number of threads hoover should use (int); default: "1" -o <filename> = file to write output nrrd to (string)
