I don't know how Mint Linux does its software, but make sure you the development
packages for QT and KDE, which include the header files in order to compile
everything. Eticre describes in the link how to do that, and I tried that today
with a fresh git clone, and that works.

No, there is no trace, but kpovmodeler allows "raw povray" text, so you could
put a trace command. I've never tried that though.....

To use a fancy word, empirical (trial and error).

There's a Software Manager in the GUI, and I use apt-get for anything else or
sometimes dpkg for .deb packages

I tried installing KDE, but no joy.
Seems I'm having problems like this
https://forums.linuxmint.com/viewtopic.php?f=56&t=116058&start=40
and I don't know if I want to start opening that can of worms right now.

I meant a sort of background image that could be used as a guide - I might try
it just in POV-Ray exactly like that and see how it works.   Real-time
drawing/drafting is just faster and more intuitive.
Almost all of the graphics/CAD packages I've taken a quick look at seem to not
be well suited to the task, and I haven't managed to figure out how to install
BRL-CAD to try THAT...
I might have to install WINE   { :( <whine> } so that I can use M$ VISIO....
sigh.
Or reboot into Win7.   :(  :(   What a PITA.

fwiw, I too tried and failed to get BRL-CAD working (on Slackware).  :-(

if you've 8G RAM or more, you could install qemu, VirtualBox or VMware, and run
your Win7 in a VM.  (you'd get cut'n'paste for free)

So, I went ahead and did that to see how painful it was.

The setup was simple - I was working on a similar thing to layout bordered
characters for Dave Blandston's set of macros, and borrowed some of that code.
I likely also have to find whatever version of screen.inc got modified to handle
an orthographic camera properly...

The CSG is still grueling and painful, and for whatever reason, I had to deal
with coincident surfaces, even though I apply the texture to the entire CSG
object LAST.

I still have to fill in one section, and there's still a weird
coincident-surface-looking strip on the rightmost view  :(

But it's built, and hopefully I can hammer out a few other pieces to go along
with this.

I probably need to write some macros to handle circles and tangents...

"SDLPOVCAD"  :D

It looks like you need Blender.....

For my Titanic-project I used the Lohmuller scale modelling to get the
deck-plans in a grid.
(http://www.f-lohmueller.de/pov_tut/scale_model/s_mod_000e.htm). For me that
worked out quite well, after adjusting it endless times to get the dimensions
correct.

Povmodeler is supposed to use only QT, not the KDE-stuff.
Kpovmodeler uses KDE frameworks 5.
I checked out the link with povmodeler with the link you gave on the 3rd, and I
didn't have any problems compiling and installing. Just did what eticre said.
If you run into problems let me knowm and I will see what can be done.
I use KDE, so our systems are different, but I'll try.
BTW povmodeler doesn't have background images.
VMware and qemu are quite good emulators, but I'm a software designer by
profession, so any occurring problems are solvable. If an artist wants to use
povray, I am quite sure he (or she) is not interested in installing this,
hacking that, just to get going...

Cheers
Ton.

Another update on the seat.

The left one is the boxes, with the gaps for the rounded edges.
The right one is filled up with cylinders and spheres to get a cushion look.
Right now the cushion looks like a toffee, so the next, and final, step is to
get a leathery look. I don't have to make it super realistic, because there will
not be a close up of these chairs, only a view through the windows.

Cheers
Ton.

My turn for a Lohmueller link. ;)
http://www.f-lohmueller.de/pov_tut/all_shapes/shapes330e.htm
In the Insert Menu, of course.

meant to reply to another post of yours, where you mention rebooting into Win to
use Visio, but couldn't find it.  :-(  anyway, while "moving in" on a newly
installed Slackware 14.2, I noticed that a 'libvisio' is now part of the s/ware.
 do you have same on your Linux distro?
code at: <https://gerrit.libreoffice.org/gitweb?p=libvisio.git>
installs what look like diagram to raw/text/html converters.

Clicking on that link just gives me a page that says "Gone".

My software manager has Vsd2odg and Vsdump, which might have uses ----

but the useful thing about VISIO is the GUI - the shape handles and numerical
readout of exact x,y coordinates, the snap and glue, alignment and spacing...
Some software comes close - but they really miss those key points and a few
small ease-of-use features.



I think that the "ideal" modeler would be something where you could "draw"
things with that kind of real-time visual feedback, but then have a way of
interspersing some code-driven tasks to add new objects or do something with the
existing ones.

I've dropped breadcrumbs here and there over the years, and it would be great if
we had a wiki page for just keeping a list of ideas and concepts and to-do type
things.  Perhaps not always things that are "possible" - but as an ideal
asymptote to approach.   I mean, how many science fiction books and shows
discussed things that we actually have and _exceeded_ in present day?


But thanks for the heads-up!   :)

"gerrit libvisio" nets that link plus a couple of other (promising looking) in
the top five.

here I see 'vsd2xxx' and 'vss2xxx' executables.

to be frank, I think you should try running the KDE desktop.  that, plus
Gnumeric and LibreOffice, will probably see you right.  (I found KDE too ..
Redmond, even back when)

before I forget, you too couldn't get BRL-CAD working?  in one of the
slackbuilds.org pages I read that Qt5 (and or 4) has to be removed from the
machine first.  :-)

the source to the .. legendary Moray was handed over ten (or so) years ago.  if
the "gods" had community spirit/sense, the source would be available here, and,
I bet, porting the source would have been done long ago too.

agree very much.  the wiki needs to be put (back) to use.
