I am trying to do as the title implies. I am looking for a tutorial or an existing github project that will show me how to make this possible. As far as what I have or haven't tryed: nothing. I have been at a lose of documentation on CEF and don't know where to begin. I am aware of the alternatives (librocket, awesomium, and berkelium). If any of these have been embbeded in GLFW successfully link appropriately. As far as finding no documentation, I have looked on CEF's website and wiki and found installation instructions and an example that uses #include <window.h> instead of opengl.
It took a bit of massaging to get it to work, as the libcef.so file is too big to be stored on github and the cef implementation is a few years old, however, I've posted a few "issues" with fixes and suggestions here to assist you. The software here is pretty good however it's completely lacking of decent documentation, and it depends greatly upon what directory you launch it from. Big hint: Launch the software from the base directory of this git.

Hope this helps.
I think this is a bit too much for a novice programmer. GLFW is a down-to-the-absolute-minium framework for creating OpenGL applications. CEF on the other hand depends on many utilities provided by the application it's built into. GLFW doesn't offer them, so you have to implement them in a way that CEF can live within GLFW. That's feasible, but requires some expierience. If you look at https://bitbucket.org/chromiumembedded/cef/wiki/GeneralUsage there's one short paragraph "Off-Screen Rendering". This is what you want to integrate it into a OpenGL project. Render off-screen and present the result through a textured quad (either viewport space aligned).

I need to display a map containing markers for some devices locations. This application runs on windows (Desktop).
I am trying to find a good technology to display the map, and use coordinates, but I am having no success on finding any.
I've read a bit about QT Location Module and its Map component which seems to be really easy to use, but I couldn't make it work on windows (Compile doesn't find the module). People said this module is for mobile only.
My question is: is there a good api for using map/location with QT, QML into a Desktop application??
Location is going to be integrated in the main release of Qt but it is currently just an Add-on Module (git download url on the fourth row).
Useful information to ease the installation can be found in this thread of the Qt forum.
Finally, I've investigated the problem myself sometime ago and I've found this site full of interesting projects which uses Google API. Each project can be downloaded from GoogleCode. I've not test any of them but they look quite promising and maybe they can satisfy your needs.
I'm developing my first Windows desktop application and I'm trying to figure out what the best approach would be to create the program's GUI.
I know, I know... I feel stupid for asking considering the amount of data on the subject on SO. However most answers seem outdated and I'm not sure if they fit my specific project. Also tutorials for Windows 8 'metro apps' are clogging my Google search results, which is NOT what I'm looking for.
I use Visual Studio. I've followed tutorials. I have basic knowledge of C and Java and extensive experience with PHP. I'm excited to learn C++, so I'm not looking for GUIs to create a GUI (like WinForms). I also don't care about managed code and portability for now, especially since I'm trying to avoid dependencies (i.e. users having to install .NET). As long as it runs smoothly on Vista and up, I'm happy.
The application
The software will teach basic physics to kids. I'd like to create a main area and a sidebar. The main area will feature a physics animation, say a bouncing ball, along with some Q&A. Users can zoom in to the animation to measure some stuff and answer the question. Users can track their progress in the sidebar. That's pretty much it.
What I've found so far
I'm getting a bit frustrated with MSDN. Most of their examples are given in four different languages (C#, C++, etc). I can't seem to get more than a bit of Hello World code from them.
I found a GDI API on MSDN and it seems like a good start for me. However I've read quite a few answers on SO saying creating layouts in pure C++ is really hard, that we're better of using frameworks like ATL and WTL. Since I'm also going to create (somewhat interactive) animations, I've wondered whether I should use gaming-targeted APIs like Direct2D.
Since all of this is new to me, and there are a lot of options, I don't know where to start for my particular application. Any tips would be greatly appreciated!
Using the raw Win32 API (no additional downloads or third-party helpers):
Here's a good primer (introduces dialog boxes, text boxes, buttons, etc): theForger's Win32 API Tutorial
And here's where you go from there (numeric up-downs, list boxes, combo boxes, tooltips, and more): Common Controls on MSDN. Most of these require you to #include <commctrl.h>.
I also found this to be a good resource that covered what the other two didn't: Win32 Developer - Window Assets
But the Win32 API doesn't seem like it does exactly what you want. A physics app for kids should have a more visual GUI than the API can provide. Good luck, though!
If you're ok with adding additional Frameworks, I'd suggest looking at Qt.
It allows to create the GUI from code only, has a good structure, and has an Interface for 2D drawing, if required.
If you are concerned about dependencies, you only have to include the Qt DLLs to your executables; no installation is required for the user.
To get started, see my (old) tutorial "Lessons in Windows API Programming".
But you really need a good book, such as edition 5 or earlier of Charles Petzold's classic "Programming Windows".
The problem with latest edition is that it's for C# and .NET, with Charles grabbing the tail of the "new way" at just the wrong time…
Disclaimer: I haven't checked the details of edition numbers.
Using the Windows API is the simplest, but producing advanced GUIs can take a very long time. Microsoft Foundation Class is a way to make the Windows API more user friendly and OOP. Does anyone have any experience with MFC?
Why not use some 2D C++ game engine, like HGE: http://hge.relishgames.com/overview.html.
I'm looking to use html5/css/js for the menu system and hud of a C++ d3d application. Ideally I'd like a 64bit MSVC10 library that I can statically link to.
So far I'm looking at:
Berkelium
chromiumembedded
QtWebKit
Awesomium
Before I commit alot of time I'd like to understand the which library would be the best for my purposes (not just from the list above). Could I use WebKit directly? Or chromium?
Even though this concept seems to be catching on right now I can hardly find a single example showing how to do it or collating relevant information.
You may also look at GUI toolkits that embed/integrate/have plugins for your listed HTML renderers (MyGUI comes to mind, with Berkelium/Awesomium integration).
Berkelium or Awesomium in general are probably a good bet, they're rather widely used for embedding Webkit and will work well. Berkelium is somewhat newer, and may have a few less features, but documentation tends to be better.
Of note is the long history Awesomium's developers have of flip-flopping licenses and suddenly trying to get money out of users (they've had free licenses before, which then were retconned into a pay-when-you-release), so that should be taken into careful consideration before touching it.
I'm not familiar with chromiumembedded and Qt has gone heavily OpenGL, severely damaging its value in graphics apps in general and likely making it useless to you.
I've been playing with WebGL quite a bit lately and I really dig Three.js. It's really lightweight and just serves as something that makes wrangling most of the GL calls a bit easier, and provides a quick way of creating basic primatives like a sphere.
Now, in native land, it seems that all the frameworks want to be so much more than that. Things like Oolong, UDK, Unity, Cocos, etc. I did a bit of googling, and the closest thing I could find was iSGL3D but I'm not thoroughly convinced it is the right answer.
Is there something more similar to Three.js that is written in native C, C++ or Objective-C that I can't find?
Here is a port of three to C++: https://github.com/jdduke/three_cpp
Core - 75% complete (TODO: Morph targets, shadows, plugin support)
Extras - 5-10% complete (TODO: Pretty much everything)
Examples - 25% complete (TODO: Examples involving morph targets an)
You're asking for a strict graphics engine only, in the same direction as OpenGL (in comparison to DirectX which again wants to be so much more than that). I'd advise Ogre3D for iPhone as the philosophy behind Ogre3d is to be a strict graphics engine.
The other one that comes to mind is recently perused MoSync mobile sdk which offers excellent OpenGL support across a wide range of platforms (albeit limited; to maintain portability).
If you're more interested in loading shaders and having the graphics engine manage the rest, I'd pick Ogre3D for iPhone.
You can always take the initiative (if you have the time of course) to write your own or start off from the ones mentioned here!
Or you can use a JavaScript engine (JSAPI for example) in a C++ editor and then move three.js on top of that. This is great as you'll only update the JSAPI and Three.js without breaking functionalities and your C++/JSThree engine will stay up to date with minimal maintenance.
Just some ideas of course!
Although I would also prefer to see a port of three.js for iOS, recently stumbled up on iSGL3d (http://isgl3d.com/).
This project serves a simple, encapsuled way to build an manipulate an opengl scene graph by code. Otherwise than some creative coding frameworks like cinder, iSGL3d comes in pure Objective C.
Works well for me yet.
You could also give Ejecta a go. They just added WebGL/three.js support.
https://github.com/phoboslab/Ejecta/tree/next
Three_cpp is good, but has stopped updating since 3 years ago. It does not support VS version below 2012.
Ogre is another good choice, which is much similar to the logic of Threejs:)
And the official site provides a very detailed tutorial, making it easy to use!
After some more searching I found a stripped down version of SIO2 called GFX that looks promising.
If you're looking for strictly ease-of-use, I'd highly recommend Panda3D. It's cross-platform (Windows, Unix, Mac), really easy to use, has extensive documentation, and a nice community around it.
I wrote a program in C++/OpenGL (using Dev-C++ compiler) for my calculus 2 class. The teacher liked the program and he requested me to somehow put it online so that instead of downloading the .exe I can just run it on the web browser. Kinda like java applets run on the browser.
The question is:
How if possible, can I display a C++/OpenGL program in a web browser?
I am thinking of moving to JOGL which is a java interpretation of OpenGL but I rather stay in C++ since I am more familiar with it.
Also is there any other better and easier 3D web base API that I can consider?
There is a lot activity recently with WebGL. It is a binding for Javascript to native OpenGL ES 2.0 implementations, designed as an extension of the canvas HTML5 element.
It is supported by the nightly builds of Firefox, Safari, Chrome and Opera.
Have a look at these tutorials, based on the well known NeHe OpenGL tutorials.
Several projects based on WebGL are emerging, most notably Scenegraphs APIs.
From Indie teams: SceneJS, GLGE, SpiderGL.
From Google: the team behind O3D plugin is trying to implement a pure WebGL backend (source) for the project, so that no plugin will be necessary.
From W3C/Web3D: There is an ongoing discussion to include X3D as part of any HTML5 DOM tree, much like SVG in HTML4. The X3DOM project was born last year to support this idea. Now it is using WebGL as its render backend, and is version 1.0 since March 2010.
I'm almost sure that WebGL is the way to go in the near future. Mozilla/Google/Apple/Opera are promoting it, and if the technology works and there is sufficient customer/developer demand, maybe Microsoft will implement it on IE (let's hope that there will be no "WebDX"!).
AFAIK, there's only 3 options:
Java. it includes the whole OpenGL stack.
Google's Native Client (NaCL), essentially it's a plugin that let's you run executable x86 code. Just compile it and call it from HTML. Highly experimental, and nobody will have it already installed. Not sure if it gives you access to OpenGL libraries.
Canvas:3D. Another very experimental project. This is an accelerated 3D API accessible from JavaScript. AFAICT, it's only on experimental builds of Firefox.
I'd go for Java, if at all.
OTOH, if it's mostly vectorial works (without lots of textures and illumination/shadows), you might make it work on SVG simply by projecting your vectors from 3D to 2D. In that case, you can achieve cross-browser compatibility using SVGWeb, it's a simple JavaScript library that allows you to transparently use either the browser's native SVG support or a Flash-based SVG renderer.
Do you really have the time to rewrite it? I thought students were meant to be too busy for non-essential assignment work.
But if you really want to do it, perhaps a preview of it running as a flash movie is the easiest way. Then it's just a matter of doing that and you could provide a download link to the real application if people are interested.
Outside of Java, in-browser OpenGL is really in its infancy. Google's launched a really cool API and plugin for it though. It's called O3D:
http://code.google.com/apis/o3d/
Article about the overall initiative:
http://www.macworld.com/article/142079/2009/08/webgl.html
It's not OpenGL, but the Web3D Consortium's X3D specification may be of interest.
Another solution is to use Emscripten (a source-to-source compiler).
Emscripten supports C/C++ and OpenGL and will translate the source into html/JavaScript.
To use Emscripten you will need to use SDL as a platform abstraction layer (for getting an OpenGL context as well as loading images).
Emscripten is currently being used in Unreal Engine and will also be used in the Unity 5 engine.

Two approaches:
Switch to Java. However, your application will suffer from a loss of performance as a trade off for portability. But since Java is everywhere, this approach ensures that your code can be executed in most browsers.
Use ActiveX, which allows you to run native binary code for Microsoft Windows. This is not recommended in production because activeX is well known as a potential security hole, but since your lecturer is the one viewing it, security doesn't seem to be a big deal. This is applicable for Microsoft platform (Windows+IE) only.
