If I use the option -c for an CIE overcast sky and calculate the illuminace, the value outside of my building is nearly 8800 lx. A check of this value with other programs (LuMagic, LumenMicro or with a handish calculation like DIN 5034 (German norm book)) brings me some trouble. For the same day at the same place are the values between 11500lx and 12000lx (also for an overcast sky). If I use the option -u (uniform sky) to produce a sky.rad file and calculate the illuminace outside the building, I got a value nearly the same like the other programs. i use the PC-Version of radiance. So my question is: Has anyone an idea what happens and is this maybe a proplem of the PC-Version?? Thanks a lot in front!

I'm surprised that your other calculations are in such close agreement. If you want a reliable absolute value for ANY sky condition, you must specify the zenith radiance either directly with the -b option or indirectly via the -B option of gensky. This is not a fault of the PC version, just a difference in the default quantity used by various programs. -Greg P.S.

The problem is that rad sets the ambient value based on the EXPOSURE setting in the .rif file, and your setting of 0.0358 results in a -av setting of 14 14 14. Any non-zero setting in a scene without sky or light sources will make the surfaces appear to glow. You need to change your exposure setting to something more reasonable for a nighttime scene in order to get the right results.

Well, as long as it reads the same geometry files like the Radiance (Unix) distribution there should be no problem. Regarding torad: it's a AutoLisp program and is only useful if you have AutoCAD. It takes a AutoCAD database and writes out the Radiance geometry, materials (all the same), a basic sunlight and groundglow and you can also choose from a set of views (named views in ACAD) Check the hobbes server (or mirror site in Swizerland) in /pub/translators (or similar), there you should find this program (if not I can mail it to you). Radout is another translator which works also inside AutoCAD and is basically a C (ADS in this case) port of the torad program. I have only used it once but the handling and functionality is quite the same (hope I remember right). Personally I prefer Gerorg Mischler's torad since I can read the code and modify it according to my needs. > > > Best regards > > Shaul Baruch > Hope this helps a bit....

Now I have another one, At the moment I'm working with a friend on an Autolisp routine that would allow conversion of a 2D base-plane drawing of a building into a Radiance file. The height for the walls exist only as extended data. I'm using MGF to describe the main geometry of the scene. For the kinkier parts I'm working directly with the .rad file. The problems occur when trying to describe a cylindrical shaped wall - I would prefer not to use 'Gensurf' for the wall, instead I'd rather use the symmetry of the floor to construct an "extruded" piece of wall. In this way the wall would be tessalated into rectangles -> no smoothing! Q: Is there an easy way of "grouping" the polygons into one object so that the surface would look smooth. The only way I can think of is to somehowe use as a material modifier a bump map and try to come up with a way of interpolating the normals of the polygons..????

Hi John, What exactly is the problem with gensurf? Its output is exactly the texfuncs you need, so why reinventing the wheel? If you stay with walls (ie. extrusion to Z direction) then the formula is relatively simple. Let X0, Y0, Z0 be the (lower) center of your arc, alpha the opening angle (start to end), a1 the starting angle relative to +x and H the extrusion height. Then you get (please test before using!): !gensurf some_material curve 'cos((PI*(PI/alpha)*s)+a1)+X0' \ 'sin((PI*(PI/alpha)*s)+a1)+Y0' \ '(t*H)+Z0' \ 16 1 -s You can tweak the number of segments (here 16) depending on the opening angle to get more accurate upper and lower edges. I intend to include this functionality into the torad/radout/ddrad suite as soon as the ddrad portion is ready for beta testing. Therfore I'd be *very* happy myself if anyone could come up with a general solution to this problem (curves roatated in space) without the need of using xform and seperate files for every single arc ... Btw: I hope that this test release of ddrad will be ready early next year. The basic functionality is allready working together with my modified copy of radout, but it still needs some more work to become usefull to someone who has never seen it before. Sorry John, for abusing your request again for this kind of advertisement ... you just seem to ask the right questions ;) hope that helps (and thanks as well for any further ideas) -Georg Georg Mischler \ / HL-Technik AG, Lichtplanung T: +49-89/72406-315 Daylighting && - o - Wolfratshauser Strasse 56 F: +49-89/72406-309 && Simulations / \ D - 81379 Muenchen, Germany E: gm@hl-technik.de From dbarnard@centcon.com Sun Dec 3 14:22:32 1995 Return-Path: Date: Sun, 03 Dec 1995 14:21:29 -0800 From: Doug Barnard To: radiance-request@hobbes.lbl.gov Subject: (no subject) X-Url: http://radsite.lbl.gov/radiance/digests_html/v2n7.html Status: RO subscribe radiance-discuss From media@centauro.polito.it Thu Dec 7 04:07:35 1995 Return-Path: From: caneparo Subject: subscribe To: radiance-request@hobbes.lbl.gov Date: Thu, 7 Dec 95 13:01:23 MET Cc: media@centauro.polito.it Mailer: Elm [revision: 70.30] Status: RO Could you please subscribe me to the Radiance discussion group?

I am conducting an experiment, in the spirit of the studies with the Cornell box, where I will be comparing a computer rendered scene (rendered with RADIANCE) with an equivalent scene in the real world. As such, I will need to find luminarires and materials in the real world whose physical data is accurately recorded and generally available. I was wondering if anyone can recommend any particular luminaires whose illumination data is available (and considered accurate) and/or materials whose BRDF data is available (and also accurate) and where I might obtain such data. Any help or pointers would be greatly appreciated.

I have had the same problems ... And I try to substitude with a generic -lX11 but when I try to use rpict or rview that use X11 output device there was a bad suprise.... I try to compile the 2.6a or b Release of radiance. With the 2.5 (Official Release ) all is ok but the new feature of 2.6 realease are really interesting.

But what You can imagine that all executable that try to to use X11 library wasn't campile. When I correct with "-lX11" the -lXmshr link, the rpict and rview executable were built. But when I try to make a render there wasn't any answer or beginning of trace. Tomorrow I will send another more exact mail. Thank Greg by Paolo Bernardelli.

I'm not in working distance of the Linux box in question so I can't give you all the details but the gist is: -RedHat Distribution v2.1 -Kernel 1.2.13 -XFree86 3.1.2 -P5/100 CPU -Diamond Stealth 64 2M DRAM I'm assuming that the X parts of Radiance (rview, ximage etc) can work at higher colour depths than 8bpp. XFree does. Anyway, if anyone out there can help it would be very much appreciated. PS: just some superfluous info for those considerin the change to ELF - if you want/need to compile the Radiance binaries make sure that the Makefile is explicit about where it can find the X libs. Running the script straight out of the box didn't work for me. -L/usr/X11/lib needed to be explicitly added to the gcc line for the X11 bits to be made. * * * * * * * * * * * * * * * * * * * * * * * Greg Elisara g.elisara@auckland.ac.nz Dept of Architecture, University of Auckland, New Zealand. * * * * * * * * * * * * * * * * * * * * * * * From hwj@lin1.gk.dtu.dk Sun Feb 18 14:06:44 1996 Return-Path: Date: Sun, 18 Feb 1996 22:38:23 +0100 (GMT+0100) From: Henrik Wann Jensen To: Greg Elisara Cc: radiance-discuss@hobbes.lbl.gov Subject: Re: Radiance and Linux/XFree86 at 16bpp Status: RO On Sun, 18 Feb 1996, Greg Elisara wrote: > -RedHat Distribution v2.1 > -Kernel 1.2.13 > -XFree86 3.1.2 > -P5/100 CPU > -Diamond Stealth 64 2M DRAM > > I'm assuming that the X parts of Radiance (rview, ximage etc) can work at > higher colour depths than 8bpp. XFree does. > > Anyway, if anyone out there can help it would be very much appreciated. I am having almost the same configuration (also Diamond Stealth) and it is true that Radiace doesn't recognize the 16bpp visual, but you can use the Diamond Card with 32bpp and Radiance runs perfectly well with this visual. > PS: just some superfluous info for those considerin the change to ELF - > if you want/need to compile the Radiance binaries make sure that the > Makefile is explicit about where it can find the X libs.

I use Slackware 3.0 ELF and Radiance compiled without any problems at all. - Henrik +-------------------------------------+----------------------------------------+ + Henrik Wann Jensen + e-mail: igkhwj@unidhp.uni-c.dk + + Graphical Communication + www: http://www.gk.dtu.dk/home/hwj/ + + Technical University of Denmark + phone: +45 45 25 16 64 + + Building 116, DK-2800 + fax: +45 45 93 83 17 + +-------------------------------------+----------------------------------------+
