pkgBSDF weird behavior

radiance-general
1

Dear Everyone,

I have been playing with pkgBSDF and that kind of stuff, and something
weird is happening (I think).

This is my scene (of course the references are present in the respective
directories).

##### CASE

!xform Geometry/Layer0.rad

#East Shading
!pkgBSDF -s system.xml | xform -t 0 0 .02 -rx 90 -rz 90 -t 5.02 1.02 2.27
-a 5 -t 0 1.5 0

#South Shading
!pkgBSDF -s blind0.xml | xform -rx -90 -t 2.54 0 1.869

!xform Skies/sky.rad

Anyway, when I try to render, it only works without ambient calculations
(-ab 0), and only with one pkgBSDF declaration (the BSDFs are in my
RAYPATH).

When I try to render with -ab 1, it returns:

4018 Abort trap: 6 rpict -vf Views/view.vf -ab 1 octree >
Images/south_only_AB1.hdr

When I try both together with -ab 0:

043 Abort trap: 6 rpict -vf Views/view.vf -ab 0 octree > Images/both_AB0.hdr

And, when I try both together with -ab 1:

4075 Abort trap: 6 rpict -vf Views/view.vf -ab 1 octree >
Images/both_AB1.hdr

Here you can check the images "just generated".

Might this be a bug? I am using the HEAD version from about yesterday...

THANKS

Hi Germán,

This is an unusual error, and not very informative. I will attempt to reproduce it if you can send me all of your files off-list in a compressed tar file attachment (if it's not too big to mail).

Best,

Thanks Greg,

I uploaded a file called "SunliteExport.zip" to the same folder.

Hi Germán,

I tried it, and I don't get an error. What -O setting are you using when compiling Radiance? Anything above -O2 has been known to generate incorrect code with gcc. Even -O2 sometimes causes runtime errors.

If you recompile and get an error using -O1, try without -O, just using -g, and run it in the debugger. This is the only way to find out where it is going wrong.

Best,
-Greg

mmm, that is weird.

I actually did not understand anything you said, haha... I just use the
"sudo ./makeall install" command. How do I choose different -O and -g
options?

THANKS AGAIN

It is working now!...

I erased and reinstalled Radiance with no -O option.

THANKS VERY MUCH GREG AND JACK

Hi German,

When you run makeall install, after you are asked for the location for the location of the executables, you will get something like the following:

Current rmake command is:
#!/bin/sh
exec make "SPECIAL=" \
    "OPT=-O2" \
    "MACH=-Dlinux -D_FILE_OFFSET_BITS=64 -L/usr/X11R6/lib -I/usr/include/X11 -DNOSTEREO" \
    ARCH=IBMPC "COMPAT=erf.o" \
    INSTDIR=/Rlib/bin \
    LIBDIR=/Rlib/lib \
    ESUFFIX= \
    CC=gcc "$@" -f Rmakefile
Do you want to change it?

If you type "Y," this will be opened up in an editor (vi is default unless you specify otherwise when you first run makeall). The "OPT=" line is the one that you should edit according to Greg's suggestions. So I think that you could first try:

    "OPT=-01"

    and then if that does not help, you could try:

    "OPT="

    This will turn of optimizations.

I think that -g gives debugging output. I think that you could do the following to compile with this:

    change

    CC=gcc "$@" -f Rmakefile

    to

    CC=gcc -g "$@" -f Rmakefile

Hope this helps,

Best,

-Jack
