-

  @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: ""

### -side \<normal side\> = how to interpret gradients as normals:

-

  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)
