I need to put some 3D images into PDF files, and PDF uses Universal 3D (U3D) formats. I don't like the U3D Sourceforge project (basically what Intel released after the ECMA standardization effort).
Does anybody know of good U3D libraries I could use? I'm using C++ on Microsoft Windows, FWIW.
VCGLib is a mesh processing library that has a U3D exporter and a variety of importers (see http://vcg.sourceforge.net/index.php/Tutorial#File_Formats). MeshLab is a tool built on top of it.
Another answer would be Visual Technology Services with PDF3D (PDF link). I've started evaluating it and I like what I see so far.
I agree with your position of not liking the U3D sourceforge project. People at my company is having problems with it when exporting large models: it runs out of memory.
The project has explicitly stated that it has memory issues on its TODO list and is dead since 2007, so I strongly recommend you to go elsewhere.

I'm looking to start developing Linux, specifically graphical elements and visuals. For example, the gnome-panel. I would be developing graphical interfaces like that. So the question is, what do I need to know? What resources do I need? I've looked all around for resources and I've discovered qt (of course) FVWM, and looked through an archived version of lynucs.org. So, what should I begin with? I haven't found a single tutorial on creating graphical elements for linux, so hopefully someone here can help me.
Thanks.
In Qt you have a very good documentation. You can start with some easy tutorials and than work on with more advanced concepts.
Here is a good starting point: http://qt-project.org/doc/qt-5.1/qtdoc/gettingstarted.html
If you are looking to develop desktop components that integrate with Linux desktops, then the answer is not straightforward. Depending on the desktop environment you develop for, you have to use different libraries.
If it is for Gnome, then definitely look into GTK+, or more recently Javascript.
If it is for KDE, then you should use Qt, as KDE is written entirely in Qt.
For working on gnome-panel (or some other GNOME component), you could look into GTK+.

I'm searching for a consultation, or maybe an opinion, a suggestion, or something like this.
I'm starting a project (desktop application) that is something like an IDE for writing books/reports. I'm planing to introduce LaTeX features, if I can name them in a such way.
So the question is: Is it possible to integrate a LaTeX script or plug-in in my software in order to have the needed features?
Waiting for questions or suggestions on my topic.
Thanks in advance!
P.S. Sorry if this topic was already posted.
Not sure I understand your question correctly. I never heard of some kind of LaTeX library or plugin of some kind, which is readily available to be integrated in other programs.
You tagged your question 'qt' so I assume, you use Qt as your framework. The only way I see to integrate LaTeX into Qt is using QProcess. Write your LaTeX code, start pdflatex with QProcess. The question then is if you can do something with the created pdf file.
Look for MikTeX and TeXworks. If you google those, you should be able to get the links to download those. That should do what you need.

I recently ditched C# for C++ because I enjoy coding in it much more.
However, I really do miss Windows Forms and how simple it was to create windows, buttons, etc.
Are there any good C++ libraries out there similar to .NET windows forms? I CAN use C++/CLI, but it bugs me that there isn't any intellisense in Visual Studio!
You may want to look at Qt. I find that the signals and slots is a fairly simple concept to pick up if you're used to Windows Forms.
I would recommend you Qt. It has got great documentation and it is really simple to learn and use. Also it has huge abilities. For example Google Earth was using it :) Here some more informations.
Try wxWidgets. It compiles on many differnt plattforms and in contrast to Qt features native widgets, significantly imporving usability.

My development team is going to build a voice chat application.
Our plan is to use a pre-made library just for this purpose, but we haven't found any good one after days of searching the internet, so I thought I would consider a question here!
So the question is:
What library / project do you recommend? We are deadly serious with this, so it needs to be a good working one. Preferable an open-source one as well.
We have been looking at some XMPP libraries and projects, but none seems to be up-to-date, tested and well-documented.
Did you have a look at libjingle ? Its the base library for Google Talk.
And on what platforms are you interested in such libraies ? I would recommend http://camaya.net/gloox/ or http://www.igniterealtime.org/projects/smack/ for portability, completeness and open standards.
www.pjsip.org
I think it is the best sip sdk around.

I am looking for a free (for commercial use) library for syntax coloring written in c/c++. Are there any out there?
I am not sure if you are looking for something to color an existing control or a control with text coloring built in. If you are looking for the later you could check out Scintilla.
Scintilla is a free source code
editing component. It comes with
complete source code and a license
that permits use in any free project
or commercial product.
GtkSourceView is a nice library for syntax highlighting and source code editing. It's used in several Gnome editors like gedit and Anjuta and is in active development; it also has a very permissive LGPL license which permits its use in commercial products.
There is also a C++ wrapper called gtksourceviewmm.
http://projects.gnome.org/gtksourceview/
another project to note is the GNU source-highlite
found this:
