I'm planning to add an interactive 3D model to my application. 3D objects of model should be rotated and moved within C++ code. The whole model is also subject to change during calculations. It also should be a widget in the main window (not a separate window). Objects are in STEP format, but we can convert them to any other needed format if needed.
There are many APIs / Tools / Libraries which I can't find which one is suitable for my application. I'm looking for suggestions or a start point.
Platform: Linux/Windows
Toolchain: C++ / Qt 4 and 5 / OpenGL
When using version 5, this can serve you to start. Loading 3D Model
Also recomend use Blender to create and export in many formats.
Another option is download models in www.turbosquid.com (there are free and paid) is faster when you have no experience in modeling

I am doing a computer vision project where i have to recognize the text in an image and output it. So I want to develop a simple GUI for my C++ code, where I can show the image in a frame and show the recognized text next to it in some text box. I have no previous experience in developing GUIs, but i think it shouldn't be hard since the interface is not complicated. I am using windows 8 and both eclipse and netbeans are installed. Please provide me with the steps and packages I need to download. Any references to some tutorials or code will be very appreciated.
I suggest to use Qt, the cross-platform application framework.
Download Qt:
Drag and drop features with C++ IDE.
Many video tutorials are available on the web.
Book: C++ GUI Programming with Qt 4 | pdf

I'm looking for the simplest/easiest way to generate 3D mesh models programmatically.
I'm working on C++ and need to import the 3D models into Blender, so there should be a way to export them into a standard file format. The models I need are relatively simple, textureless, no materials, no shading, just geometry.
What kind of tools/libraries are there to achieve this? The easiest method the better (I'm actually quite fluent on c++ but don't really want to spend much time learning a complex API)
Any reference to documentation or tutorial would be highly appreciated :)
You can generate 3d meshed programatically in any language and save then as OBJ Wavefront OBJ. This is the easiest I can think of. OBJ can be imported to virtually anything 3d related blender, 3ds, maya, mari, zbrush, mubdox etc.

I'm trying to show some files (html format) in a page of my application.
If anyone has an example on how to do this, even remotely related, I would be grateful.
So far I haven't found anything in my searches so I welcome any links, suggestions.
Thanks.
It depends on the OS version you are using and its configuration, but you should be able to use the HTML/DHTML APIs:
http://msdn.microsoft.com/en-us/library/ee492824(v=winembedded.60).aspx
If you need to rendere some HTML (and not just parse it) you may host the browser control inside your application and define a Win32 XAML controls that will contain it. This control doesn't support all the XAML features (rotation, transparency etc.) but can be placed inside a layout and controlled by your app.

I'm in no way an expert on programming, not even close, and I'm event worse at GUI programming. But for a project I need to do some simple point datasets and line plots. And I need to be able to do dynamic updates.
Does anyone know any good frameworks for doing this, I would like either a Cocoa or perhaps a Qt C/C++ framework.
The other option would be to make a Qt widget myself, there are properbly lots of good tutorials out there on that, does anyone know any?
My data is going to be (x,y) with a sliding window over the x-axis.
Lots of suggestions here Is there any 'out-of-the-box' 2D/3D plotting library for C++?
qwt is what you need if you want to use Qt.
It's really poorly documented but there's a tutorial here
MathGL is GPL plotting library which have both: QMathGL for Qt widget with plot, and mglGraphQT (or mglGraphFLTK, or mglGraphGLUT) for external window with plot. See these samples for more details.

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.
