Radiance on Cygwin: Starting problems

radiance-general
1

Hello,

I am a graduate student at Arizona State University and I am going to use
Radiance for my thesis. The computer maintenance guy at school here helped
me install Cygwin on my notebook computer and Radiance on top of it. I have
just begun to learn Radiance and when I input a simple room as specified in
the Introduction chapter 1.3.1 of the book "Rendering with Radiance" by Greg
Ward Larson and Rob Shakespeare, I get the following errors:

$ oconv room.rad > test.oct
oconv: fatal - <room.rad>: unknown type "bright"

$rview -vp 2.25 .375 1 -vd -.25 .125 -.125 -av .5 .5 .5 test.oct
I get a windows pop up error message saying rvu.exe - Unable to locate
component, This application has failed to start because cybX11-6.dll was not
found. Re-installing the application may fix this problem.

I used the NoteTab Light text editor to create the file room.rad.

Any advice on how to proceed will be greatly appreciated. If somebody with
working knowlege of Cygwin/Radiance lives around Tempe/Phoenix/Mesa (Arizona
State), I would like to get my notebook computer to you to make sure
everything needed is installed properly. Please help.

Hi,

The oconv error probably relates to a problem in the scene definition for the room. Unfortunately I do not have the book handy so I cannot check description. I would suggest double checking against what is indicated in the book.

Since the scene does not compile (oconv: fatal ....) you will not be able to rvu it anyway. It also sounds likely that you do not have X installed with Cygwin. I would suggest checking to see of X was installed as part of the cygwin installation. If not you should be able to run through the cygwin setup program to get additional programs/software such as X.

On page 21 of RwR, the input file <room.rad> specifies a light definition of:

···

************

# this is the material for my light source

void light bright
0
3 100 100 100

************

The structure for the definition is

MODIFIER TYPE ID
0
3 R G B

i.e., "light" is the type and "bright" is the id.

Make sure you did not accidentally type:

"void bright light" [that is, switched "bright" and "light" by accident] on the first line of the definition.

Hope this helps, been there done that!

Hey,

Thanks Kirk, I had made the "void bright light" mistake which I corrected to
successfully create the octree file.

Coming to the second error:

$rview -vp 2.25 .375 1 -vd -.25 .125 -.125 -av .5 .5 .5 test.oct
I get a windows pop up error message saying rvu.exe - Unable to locate
component, This application has failed to start because cybX11-6.dll was not
found. Re-installing the application may fix this problem.

My installation folder "C:\radiance_stuff\cygwin\usr\X11R6\bin" contains
only a run.exe file and nothing else. I rerun the setup with X11R6 selected
and the message at the end says "nothing needed to be installed". Does that
mean the file is missing from the installation itself? What can I do to
correct the situation?

Ramana.

Hi Ramana,

Can you confirm if you can get something like an xterm started from cygwin? This would be one way to confirm the installation of X.

Alas, I use a Mac.

Rock on.

I'm not sure if this applies to Windows, but is your DISPLAY environment variable set to launch X11 when you invoke rvu? I'm way out of my league here, but I know that if I try running rvu from my Mac OSX Terminal app without the DISPLAY variable set, no dice. If I run rvu from my X11 app, it works - I assume it is because in X11, the default display is X window.

Again, I ain't no Windows person, so I'm shooting from the hip here.
