This directory contains common auxiliary files used by Radiance. Files with the ".cal" suffix specify procedural patterns, textures and coordinate mappings. Files with the ".fnt" suffix are font descriptions. Files with the ".oct" suffix are compiled scene descriptions for use in instances. Files with the ".mat" suffix contain the names of materials used in the corresponding ".oct" file, for exclusion in the interreflection calculation using the -aE rendering option. Files with the ".pic" suffix are images for patterns. Note that most pictures are normalized to a value of 1 rather than the more usual .5, and must be displayed with the -e -1 option. This is so the material reflectance given in the scene description holds true. (Suggested reflectances are given in parentheses.) adobe.cal Texture for cracked adobe surface ball.cal Coordinate mapping for spheres bark.cal Procedural pattern for tree bark brick.cal Procedural pattern for brick carpet.cal Procedural pattern for carpeting covelight.cal Calculation of reflected fluorescent light cyl.cal Coordinate mapping for cylinders dirt.cal Fractal dirt function fisheye.cal Coordinate mapping for fisheye patterns glazing.cal BRTDfunc definitions for coated glazings globe.cal Coordinate mapping for Earth.pic gloss.cal Texture for glossy reflections jigglepic.cal Coordinate jiggle for irregular natural patterns marble.cal Procedural marble pattern orange.cal Procedural orange texture picture.cal Common coordinate mapping for patterns plink.cal Definitions needed by materials in lib/material.rad rayinit.cal Initialization file and common definitions rev.cal Surface normal interpolation for genrev skybright.cal Sky brightness calculation for gensky slate.cal Procedural texture for slate stone source.cal Common coordinate mappings for light sources (ies2rad) speckle.cal Procedural speckle patterns for sand or granite surf.cal Surface normal interpolation for gensurf tilt.cal Tilt correction used by ies2rad weave.cal Procedural weave pattern winxmit.cal Approximation to window transmittance for sec. sources woodpat.cal Procedural woodgrain pattern woodtex.cal Procedural woodgrain texture lamp.tab Table of lamp types and their CIE color coordinates helvet.fnt Helvetica font (from Hershey set) hexbit4x1.fnt 4 by 1 hex bit font for creating bitmaps n.150.oct Spray of needles used by sapling.oct sapling.oct A small pine tree sapling tree.oct A larger pine tree built from sapling.oct tree.mat Exclude material list for tree.oct and sapling.oct alberta.pic A scanned vacation slide from Alberta, Canada brick.pic A scanned brick pattern (staggered layout) (rho=16.3%) brickweave.pic A scanned brick pattern (weave layout) (rho=19.8%) cabin.pic A rendering of the cabin during winter Earth.pic A picture of the Earth forestfl.pic A scanned forest floor pattern oakfloor.pic A scanned pattern of an oak floor pine.pic A rendering of a small pine-like bush pinebark.pic A scanned pattern of pine tree bark richgrove.pic A photograph from Richardson's Grove in California shingle.pic A scanned shake shingle pattern tulips.pic A rendering of a tulip sculpture source/ Directory for light sources of different manufacturers lib/arch.map Default material mapping for arch2rad lib/arch.mat Default materials for arch2rad lib/coord Radiance description of a coordinate system lib/gamma.pic Picture for monitor gamma determination lib/macbeth_spec.pic Picture showing Macbeth color checker colors lib/material.rad Library of RADIANCE materials from ADELINE package lib/rgbw.pic Picture with red, green, blue and white for mon. calib. lib/testimg.pic Picture running through positive and negative primaries lib/testroom Small test room used by objpict and objview meta/ Directory with library files for metafile 2-d graphics
