<div>hi, I am trying to capture 2D images of an object from several viewpoints. As far as I know those images do not exist until we render the viewing window .So far I 've done this by render the window while rorating the camera, it works but not so fast. Before it is displayed onto our screen , is there anyway to get to the image? I tried the OffScreenRendering with Mesa, but it turned out to be much slower than the traditional way.

<div> thank you verymuch for reading</div>
