DESCRIPTION

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

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

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

genrhgrid is a program to generate Radiance section grid representations

glaze

Complex glazing model (goes with glaze1.cal and glaze2.cal)

mgf2inv

mgf2inv is a translator from MGF to Inventor (or VRML) format

mgfilt

mgfilt is a filter for MGF

nff2rad

nff2rad converts Neutral File Format input to Radiance scene descriptions.

objpict

objpict makes a nice multi-view picture of an object. Command line arguments contain materials and object files.

optics2rad

optics2rad converts Optics 5 output to correct Radiance input.

pbilat

Bilateral Filter.

pcwarp

Intended as more general substitute for macbetcal, but never quite worked.

pdelta

pdelta computes 1976 CIE Lab deltaE* between two Radiance pictures.

pgblur

pgblur applies Gaussian blur without resizing the image. More efficient than straight pfilt for large blurs.

plot4

plot4 is a program to put four metafile pages onto one.

ra_hexbit

ra_hexbit is a program to generate bitmap files for use with hexbit4x1.fnt.

ra_pfm

ra_pfm is a program to convert to/from Poskanzer Float Map image format using pvalue.

rlux

rlux computes illuminance from ray origin and direction.

vinfo

vinfo is a wrapper around vim to edit information header in Radiance files.

xyzimage

xyzimage is a program to display one or more CIE XYZE pictures using ximage.
