One thing that I would try:
First, #declare your object.
Next, find it's bounding box using min_extent() and max_extent().
Average the returned values.
Use that averaged value as the look_at for the camera.

If you still get nothing:
Maybe the object is to small or large or to distant.
Try moving the camera toward the object or the object toward the camera.
Try scalling the object up or down. Start using factors of 10.

Maybe it's to dark.
Try any of the following:
Use a white background.
Use only ambient and temporarily set the colour to some light shade, 
like rgb<1,0,1>.

relatively dark and warm.
So, the various C_marronxx are variations of that brown.

Hi,

I've modified my project files to keep the essential and it still doesn't work.
I've uploaded the files (pov, inc and png of heightfield) to a server in a zip
archive. The files are quite small.
Here is the path to download the zip file:
www.ant01.fr/fichiersAnt01/povray/pov_help_macro.zip

Often just performing this task will identify the problem.

Seems to work here - I get a pink coloured background with a beige wave 
going across this middle. Is this what you expected?

I got what I expected in windows 10 with the files mentioned above and the
images you told about but once in Linux Ubuntu (with my laptop, with the desktop
pc I get the expected pictures )I get a pack of 16 totally black pictures.
Lately I tried to tweak the admin rights in folders, removing non ASCII
characters, but it still doesn't work.

I will copy the file of Ubuntu desktop to the Ubuntu laptop. But don't worry
about that , it works on my desktop computer, it's just that I' d like to solve
the problem :(.

It's quite apparent to me at this point that /something/ is fishy about
the POV-Ray binary you're using on your laptop.

This immediately raises the following questions:

- Do any of the sample scenes render properly on your laptop?

- What does "povray --version" output on the two Ubuntu computers?

- What versions of Ubuntu are you using on the two machines?

My current best bet is that you're using a different version of POV-Ray
on the laptop machine, and that there's some bug in that version. If
that is the case, I'd really like to get down to the bottom of it.

Hi,
On the desktop PC in the terminal after a "povray --version" I get :

And yes, on the laptop I installed povray via the depots "trusty backports"
whereas on the desktop PC I compiled the sources I download on www.povray.org.

Post a reply to this message

Hi , everybody
I have good news. :)

I removed povray I get from the depots "trusty backports" and installed povray
with the source code from www.povray.org > github and the code I posted in the
post above works fine now. I tested the render example after compiling the new
povray and that was good too.

I want to thank all those who were willing to help me. :)

Antoine.
