   [c++] Opengl get stream from WebCam
  HY.I'm would use a program like artoolkit plus ,that offers a lot of function for detect marker and visual recognition.My problem in particulary is how to get a stream from webcam and draw it to screeen after do the image processing in real time wit altoolkit plus.Possible the library must be multiplatform(linux and win).ps.There are some examples for artoolkit plus?Thanks.   
  This does not really have anything to do with OpenGL. What is the question exactly? Are you asking how to grab a frame from video and display it on an OpenGL texture? On Windows you would use DirectShow to grab the frames.Or are you asking how to use ARToolkitPlus? ARToolkitPlus is the mobile version of ARToolkit, but it was replaced years ago by the Studierstube Tracker library. The library comes with tons of samples and does things like grabbing video frames automatically. Studierstube is closed source though. ARToolkitPlus is still available, but I don't recommend it as it is not as full featured as Studierstube and it is not being developed anymore. For non-mobile platforms, use Studierstube or ARToolkit, which is open source. Both come with samples.   ;Quote: but it was replaced years ago by the Studierstube Tracker library.

Hope this helps :-)
