  POVRAY include bug ??? (Message 1 to 6 of 6)

Bob R has reported a problem when rendering the balcony scene in the 
advanced directory using pyvon.


I found out that I had the same problem when using pyvon.

The command that Pyvon launches on my computer is the one that follows.

"/home/fabien/mlpov/82/povray-3.50c/src/povray 
Input_File_Name="/home/fabien/mlpov/povray-3.50c/scenes/advanced/balcony/balcony.pov" 
  -l/home/fabien/mlpov/povray-3.50c/scenes/advanced/balcony +v +p 
-l/mnt/win_c/temp -f +a0.1 +am2 
-l/home/fabien/mlpov/povray-3.50c/include +GF${HOME}/err.txt +q9"

When I use a console, cd to the balcony directory, starts povray to 
raytrace the balcony scene, it works.

BUT, when I use a console, remain in my home directory (ie /home/fabien) 
and render the balcony scene, I get the same error as when I use pyvon.

Below is a copy of my console. On the first line, the command line that 
starts pov and the messages that POV outputs.

My include files are correctly quoted in my .povrayrc as shown above

NOTE :
There is a glass.inc in /usr/local/share/povray-3.5/include AND in the 
balcony directory.
Could this be the problem ?


Something else : I did the same test as root : There is no 
writing-reading problems.


Could some of you try the same : Starts a raytrace of balcony.pov from 
your home directory or anywhere else but the balcony directory and tell 
me if it works.



Thanks

I have a simplified command line here which gives similar results:

I get the same behavior as you do:

$ povray -l/usr/share/povray-3.5/scenes/advanced/balcony 
-i/usr/share/povray-3.5/scenes/advanced/balcony/balcony.pov

has the Glass object error in table_stuff.inc. It looks like the library 
parameter is being referenced at the first level of including because it 
does correctly find table_stuff.inc (as well as sky.inc) in the balcony 
directory. Both of those are includes in the balcony.pov scene file. But 
the passed library path doesn't seem to carry into the included files. 
In this case balcony.pov includes table_stuff.inc, so far so good. But 
table_stuff.inc includes glass.inc and this is where it is breaking 
down. So the includes of includes are not being looked for in the 
library path parameter or the order of looking changed. At least that's 
the behavior I'm seeing here. I have no idea why though.

I wonder if it works for include files that have includes that do not 
name clash with the existing standard includes. It looks like it works 
correctly in such cases. The balcony.pov scene includes table_cloth.inc 
before including table_stuff.inc. table_cloth.inc includes cloth.inc and 
  POV-Ray doesn't choke on that include. So maybe the order of includes 
gets shuffled at some point or is search differently? Puzzling stuff!

I re-named the local "glass.inc", and "balcony.pov" renders OK using
Pyvon.

It may be a POVray(Linux) problem.

I've been trying out Kdevelop/Qt. I put together a little program[1]
with a dialog that runs POV. No "cd" to any directory, simply calls
povray with a path/filename, and it can't find "sky.inc" when I try
"/usr/..../povray-3.5/.../balcony.pov". On renders that do work, it
puts the *.png in the directory where the executable is run from(that
doesn't seem right, even with my weak little program).
Over a month in Linux, and I can't figure out CWD (Current Working
Directory). <G>

[1] - two days reading, 20 minutes work!! <G> I can't believe it even
works!

That's why I had to add the path to the current working directory
as in
-l/path/to/the/location/of/the/pov/file

I guess, that's something we will have to ask to the advanced users group.
I think you have to look at the code to know how the include files 
behave when they are deeply nested and what happens when the same name 
is used more than one time.
I renamed glass.inc to verres.inc and changed the files accordingly and 
it works.
So in this case, I am glad to know that pyvon is not the culprit.
