radiance-experttools — Specialty programs of the Radiance package, used
This manual page documents briefly the debugcal, genambpos, genrhgrid,
glaze, mgf2inv, mgfilt, nff2rad, objpict, optics2rad, pcwarp, pdelta,
pgblur, plot4, ra_hexbit, ra_pfm, rlux, vinfo and xyzimage commands.
These specialty programs of the Radiance package are commonly only used
by experts, therefore the Radiance distribution does not contain full
manpages for them.
debugcal is a script to debug cal files for Radiance
Takes octree and rcalc options as arguments. One of the rcalc options
should be -f calfile. Note that the real arguments A1, A2, etc must
also be given. Input is a ray origin and direction, such as that
produced by ximage.
genambpos is a script which puts coloured markers (spheres) at points
where hemispherical sampling was initiated. The locations and levels
are taken from the binary ambient file.
genrhgrid is a program to generate Radiance section grid
Complex glazing model (goes with glaze1.cal and glaze2.cal)
mgf2inv is a translator from MGF to Inventor (or VRML) format
mgfilt is a filter for MGF
nff2rad converts Neutral File Format input to Radiance scene
objpict makes a nice multi-view picture of an object. Command line
arguments contain materials and object files.
optics2rad converts Optics 5 output to correct Radiance input.
Intended as more general substitute for macbetcal, but never quite
pdelta computes 1976 CIE Lab deltaE* between two Radiance pictures.
pgblur applies Gaussian blur without resizing the image. More efficient
than straight pfilt for large blurs.
plot4 is a program to put four metafile pages onto one.
ra_hexbit is a program to generate bitmap files for use with
ra_pfm is a program to convert to/from Poskanzer Float Map image format
rlux computes illuminance from ray origin and direction.
vinfo is a wrapper around vim to edit information header in Radiance
xyzimage is a program to display one or more CIE XYZE pictures using
