KPOV - want to help...

I see not much activity on the list or on the bugs lists at KDE.org..

But it looks from your Buglist in the Code 3.5 that some of these may have
been completed.

I noticed that some items if you do an export then an import that if fails to
import all the items..

I would like to contribute to this project if just to help on this item..

One idea on this is when it does say it is not going to import the object
could we import instead as a Raw Povray item..

Not sure this is possible i have not looked over the code fully yet..

I am a newbee at Open Source and would like to help with this project at some
stage..

Oh i am not a graphical person not an artistic bone in my body, Just came
across this trying to simulate the Bar I was getting built by my carpenter..

Hi, Michael!

I'm a regular kpov-user, willing to test new functionality, and it would be
wonderful if you could help the team.

I would recommend your first stop to be Friedrich A. Lohmueller's descriptions
and tutorials for POV-ray 3.6.1 at
http://www.f-lohmueller.de/pov_tut/pov__eng.htm

Friedrich has done outstanding work, covering nearly everything in a visually
pleasing manner, from the basics, the more advanced and animations using
splines. Just trying to follow his examples with kpovmodeler will show you
what is missing - recommended approach!

Hints - GUI enhancement:
* generally do away with the need for RAW POV
* how to add includes (documentation issue?)
* how to do some of Friedrich's declarations (documentation issue?)
* how to construct a POV-ray while loop without using RAW POV
* how to construct a spline declaration to use in animation, see Friedrich's
example
* how to add the clock variable to an object
* how to save animation frames with different names

I would recommend the POV-ray 3.6.1 documentation at
http://www.povray.org/documentation/view/3.6.1/212/
as your second stop.

Cheers,
Haakon

Thanks for the reply looking at the documentation right now seeing the
differences and testing my install.. correctly..

Mandriva RPM is faulty.. (The download works perfectly..)

This is a fantastic program I agree and I have just opened your links. for
further info..

I will start at the top and see what i can help with..

Most bugs that are still open are wishes or small usability issues. But
you are right, there is not much activity at the moment as we are all
quite busy with our real live jobs.

Not sure, too.
Povray parsing is quite tricky.

Problem is:
KDE 3.5 is released and afaik there is no 3.6 planed. That means new
features can be added only for KDE 4.0 which means KPovModeler has to be
ported to Qt4 and KDE4. I started this port already but as long as KDE4 is
not stable development on the project doesn't make much sense.

Andreas

KDE 3.5.1 was released today, featuring fixes to over 150 reported bugs and
many other small improvements

So from that announcement i think bug fixes and small enhancements are allowed
to be included..

Can i help you also on the QT4 rewrite, I can do some of the dogs body work
like the documentation links for the help buttons to 3.6.1 which i have
completed already for the current version..

I realise all are working hard i did not mean any disrepect, Sorry if you
thought it was that way..

I spend hours at work as well and there are times one must drag oneself away
from a problem and focus on other items for a while.

Yes, that's right, as long as they are real bug fixes and do not add new
texts to translate.

Sure, any help is welcome :)
First step is to set up a linux with a kde4 snapshot. I will write you
some hints this evening.

No no, I did understand it the right way.

Well, that "while" lasts now some years and I don't think that will be
better the next time.

Yes, I agree.  The homepage of Andrea Lohmüller and Friedrich A. Lohmüller is
marvelous!

A big problem with links pertaining to POV-ray is that so many are not
working. A large proportion are the results of someone playing around with
the basics, many of those that go further are out of date (great images,
wrong code), and the updated remainder is unevenly devided between scientists
(few), architects (fewer) and artists (fewest). Those that are updated
usually have fantastic images!

Search engines are most helpful if you search for directly for images, using
"povray" or similar for key word. You immediately see the good stuff, and
where they are located.

A safe assumption is "The best know the rest", meaning the personal link
collections of those few updated sites I mentioned above usually lead you to
the sites of other talented POV-ray/3D artists.

Here is my current list of talented people:
* http://www.f-lohmueller.de/
* http://www.aust-manufaktur.de/
* http://www.econym.demon.co.uk/
* http://www.renderosity.com/
* http://home4.inet.tele.dk/ibras/
* http://www.timeref.org/
* http://www.oyonale.com/ - Gilles Tran - enough said :-)
* http://www.digimation.com/ - they sell 3d models - I haven't bought any, but
it's nice to see what the asking price is. You might get inspired to get into
3D just for because of that ;-)

If you want more, just follow the advice in the paragraph above the list. :-)

Cheers,
Haakon

Hi Michael,

Developing a complex CSG object (Constructive Solid Geometry) is hampered by
the wireframe not showing the result of a union, merge, difference or
intersection.
 
I would suggest using the GNU Triangulated Surface Library - or GTS for short
from http://gts.sourceforge.net. The library is released under the GNU GPL,
and is already in use by a number of free software projects, among them K-3D.
Documentation/library reference and example files are available.

I've added this to the wish-list, and was assigned the name Bug 121596. If you
have time to investigate/implement it would be much appreciated.

Cheers,
Haakon

Hi Haakon,

that was already at front of my internal wish list.
But that's a too tricky task to start with as it needs a lot of
knowledge of the internal object representation and background tasks so
that the gui is not frozen when calculating complex csgs.

Regards,
Andreas

I didn't realize it was such a tall request, but I'm happy it is on your list.
It's probably just me, but I found the KDE web SVN for kpovmodeler a bit
confusing - deprecated files, lots of files moved about.  I would like to try
and compile the latest kpovmodeler from source - is there a URL I can use to
get it?

Cheers,
Haakon

The way i did the 3.5KDE version is

Get the branch 3.5 svn

svn://anonsvn.kde.org/home/kde/

click down to the /branch/3.5/

I use kdesvn

Then i got the lot a bit of over kill but wanted other items to look at
aswell.

You may only want the Graphics items..
/kdegraphics/kpovmodeler/

But i am sure it needs files from some of the other directories..

Then go into the directory you want to make and install once downloaded and do
these things.

make -f Makefile.cvs
./configure
make
su
make install

And its done easy as pie..
Took me a while to work out at first..

Thanks Michael! There seems to be some trouble with my proxy settings when
using svn. I'll have to figure that out later.

Hi, ( Yes I'm still watching the list :)

Been busy with real life, but as far as CSG work I did create this

http://www.leonscape.co.uk/linux/csgcalc/index.html

and I had started to integrate some with KPM, but I've been extremley busy, as
Andreas said, it very complex and slow, as soon as you get to any decent
amount of complexity things slow down dramatically.

CSG is great for ray casting but its a pain to reproduce with wireframe.
especially with a povray type set up where anything can be re-calculated at
any point, most of the the other 3D programs that do CSG through an editor
make it a one time operation ( Say Truspace for example ) doing it real time
is almost impossible.

A big recalculate button, is the only way I could think of even making this a
possibility for now, ( Holding a separate wireframe as part of the CSG rather
that a combination of the child objects, move the child and hit recalculate
to get the parent to update ) or until someone could come up with something
better :)

I really should get back to this my real work is such a grind though...

I said i would help and i have been busy and bored with other projects at work
lately.

I found a web site called English Breakfast Network when reading the KDE QA
mail list , and noticed all the fixes that they suggest in the new version 4.

I have my KDE4 now working and would like to plug away at these if no one has
any complaints, since i know cleaning up code to a standard can be annoying
at times, but it will also give me the push to do something and really go
through the code more..

Reading the last list of ideas you were all talking about sounds like some
good new input..
