Hi, I'm using a render script as follows.  When I run it using povray 3.6, it
shows a preview display window, which is what I obviously want when I set
Display=On and use +D on the command line.  With povray 3.7, I do not get a
display window.  Has something changed?
Thanks

cat <<EOF >tmpy.ini
Output_File_Type=n
Verbose=On
Pause_when_done=Off
Start_Row=0.0
End_Row=1.0
Video_Mode=1
Display=On
Antialias=On
Antialias_Threshold=0.99
Sampling_Method=2
Declare=Shadows=1
;; Declare=camPath=1
EOF

povray3.7 -Itmpy.ini +H${height} +W${width} $debug  +D  +SP256 +P myfile.pov

 From the above code I presume you're using the Linux version of POV-Ray.

Make sure that before you build POV-Ray, the SDL (Simple DirectMedia 
Layer) library development package (SDL-dev I guess) is installed on 
your computer. If this is not the case, POV-Ray cannot build with 
preview window support.

As for POV-Ray 3.6, my guess is that you might have obtained it as a 
pre-built binary with the SDL library linked statically.

Did 3.6 even use SDL at all? (POV-Ray has been around for a really
long time, way before SDL, and it has always shown a preview window
on Unix/X. I think in the past it called the X API directly.)

You are right, 3.6 did not use SDL, but tried to handle the X11 options
itself.

Whatever. I haven't bothered about Linux render preview until a few days 
ago, when I needed to test some changes in the code regarding our use of 
the std:: namespace.
