💖 teem-miter(1) — User Commands 💖

okay bestie, sit down, hydrate, because today we're talking about teem-miter, a simple but effective little volume renderer 🎀 and honestly? it ate. this whole page is literally the manual page for it, so let's get into it ✨

💅 DESCRIPTION 💅

bestie. this is a renderer. it renders volumes. it's simple, it's effective, and it's little. the way that it just does that? obsessed. 🔥

👑 OPTIONS 👑

like, there's a LOT, and every single one of them matters, so we're not skipping a single one, periodt. 💖

• @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:
  • "1": normal points to lower values (higher == more "inside")
  • "0": "two-sided": dot-products are abs()
  • "-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) 💾
