Genambpos does not work well

Hello

I tried to visualize the sampling points with genambpos, but I get the following error message.

"Missing -aa setting in header "

The parameter settings are as follows

rtrace -I -h -dp 2048 -ar 2 -ms 0.063 -ds .2 -dt .05 -dc .75 -dr 3 -dj 1 -st .01 -ab 2 -aa 0.5 -ad 1 -as 0 -lr 12 -lw .0005 -af test.amb test.oct < test.pts > test.dat

How can I use genambpos?

Please answer.

Are you running genambpos on the ambient file “test.amb”? Are you on a Unix machine, or is it Windows? What is the output of “getinfo test.amb”?

I didn’t explain it well enough. I’m sorry.

Are you running genambpos on the ambient file “test.amb”?

Yes.

Are you on a Unix machine, or is it Windows?

I use Windows.

What is the output of “getinfo test.amb”?

It is “ambinfo.txt”.

The contents of the .bat file are all written below.

Thank you in advance.

I think the problem is that genambpos.pl only runs under Unix. Most of the Radiance Perl scripts will run under Unix or Windows, but not this one. It was never adapted properly for Windows.

Greg,

Thanks for letting me know.
I just tried it on Linux and was able to use it successfully.
That was a very rudimentary question…

Thank you very much.

Not rudimentary at all. How were you supposed to know it doesn’t work under Windows? We need to add an error message!

Cheers,
-Greg
