<p>Frame graph node for render capture</p>
<p>The <a href="qt3drender-qrendercapture.html">QRenderCapture</a> is used to capture rendering into an image at any render stage. Capturing must be initiated by the user and one image is returned per capture request. User can issue multiple render capture requests simultaniously, but only one request is served per <a href="qt3drender-qrendercapture.html">QRenderCapture</a> instance per frame.</p>

<p>Used to request render capture. Only one render capture result is produced per requestCapture call even if the frame graph has multiple leaf nodes. The function returns a <a href="qt3drender-qrendercapturereply.html">QRenderCaptureReply</a> object, which receives the captured image when it is done. The user is responsible for deallocating the returned object.</p>
