Re: [osg-users] Webcam image as texture using OpenCV
Hi Charlie, Hi, I am looking a way to use the image grabbed from a webcam using OpenCV and then use that image as a texture in a osg app. Taking the osgmovie example, I already tried to create a subclass of the ImageStream class but Im a little lost trying to do it this way so far I already know how to convert an IplImage to an osg::Image and I'm able to take ONE image from the webcam this way, but now I have no idea in how to do update the image every 1/30 second to create the live stream. You need to call the method dirty() whenever a new frame is grabbed to tell osg to update the texture associated with the osg::image object.

Sombody already solve this issue? Any code to perform this would be really apreciated.

Re: [osg-users] Webcam image as texture using OpenCV
Hi Charlie, Have a look at the osgdb_gif plugin. It has an internal GifImageStream class which is also derived from ImageStream but much more light-weight. Hope it helps.
