Notes on what I noticed related to POV-Ray.

I've upgraded my main machine to Ubuntu 20.04.1. While I do my own 
compiles and run time set ups. I did look some at the povray package
and into couple of "no longer supported by Canonical packages" used by 
those compiling there own versions of povray.

With the later, the support for doxygen and sld1.2 development packages 
apparently no longer comes from Canonical - but they are still Debian 
packages and installed/install-able. In other words the Debian packages 
are now used straight up is the change.

In a surprise - to me at least - the Debian folks (bullseye) have split 
the povray (1:3.7.0.8) installation into several packages:

fonts-povray - Persistence of vision raytracer (3D renderer) fonts

povray - Persistence of vision raytracer (3D renderer)

povray-doc - Persistence of vision raytracer (3D renderer) documentation

povray-examples - Persistence of vision raytracer (3D renderer) sample files

povray-includes - Persistence of vision raytracer (3D renderer) include 
files

I think this sort of split a good idea. It more or less matches what 
I've done in povr for my own development. Excepting, thus far I've kept 
a few core include files(8) with povray itself. The functions.inc file 
especially is strongly coupled/aligned to the particular povray compile 
due the inbuilt (c++ compiled) functions.

I think all good. I was worried about the includes, but that package is 
marked as a recommended one so it will get installed too - unless a user 
does something uncommon to suppress the installation of recommended 
packages. Further the fonts are in the include package too as always so 
povray will find them.

Props to the Debian package folks for fonts-povray. What they've done 
there is create a package putting the povray fonts in:

/usr/share/fonts/truetype/povray/crystal.ttf
/usr/share/fonts/truetype/povray/cyrvetic.ttf
/usr/share/fonts/truetype/povray/povlogo.ttf
/usr/share/fonts/truetype/povray/timrom.ttf

which means a good many editors will pick them up if that package is 
installed.

The one other change I picked up is the scene files are now installed 
in: /usr/share/doc/povray/examples. The scenes were previously installed 
in: /usr/share/povray/scenes.

Aside: With previous debian/ubuntu/other-linux packages or if using the 
usual build and install scripts yourself, 'povray' likely 'povray-3.7' 
or similar on your system. Further, the directories involved might be 
/usr/local/share over /usr/share.

I am going to try running POV under Ubuntu soon.

Is there an installation tutorial somewhere?

What editor do you recommend? I would prefer something like the Windows 
editor so I don't have to learn multiple things at the same time.

Thanks.

Mike

from what little I know, D Balaska's 'qtpovray' may be your best bet.

Linux Mint is derived from Ubuntu. This worked for me.

mkdir src
cd src
wget https://github.com/POV-Ray/povray/archive/3.7-stable.zip
unzip 3.7-stable.zip
cd povray-3.7-stable/
cd unix/
./prebuild.sh
cd ..
./configure COMPILED_BY="<me@athome>"
make check
sudo make install

Given your editor constraint - what jr said.

As for install tutorials look for ones on how to install packages with 
Ubuntu itself. Ubuntu is Debian based so v3.7 is a package available for 
install. There are graphical package managers, but I open up a terminal 
window (~ a command line window).

To see povray related packages available:
    apt-cache search povray

To install it:
    sudo apt-get install povray

To see what is installed:
    dpkg -l | grep povray

You can install Dick Balaska's qtpovray with the commands above, but 
only after adding extra package repositories - and I forget how to do 
that off the top of my head. There were pointers in his qtpovray posts 
IIRC.

If you plan to hack code yourself, you need to compile - so do something 
more like what Hj.Malthaner suggested is a way to go.

Lastly, if you are using Blender or you plan to use it, it has an editor 
for POV-Ray SDL and methods to kick off and manage renders. It's 
available as an install package too.
