I tried using QRenderCapture by combining the rendercapture-qml and shadow-map-qml examples to be able to capture a rendered image at a fixed resolution. I feel like i am close, but just get a black image when i try to capture the image.
I would appreciate it if anyone could take the time to look at what i have gotten so far, and tell me what i am doing wrong: https://u2671948.dl.dropboxusercontent.com/u/2671948/multiviewport.tar.gz On 19. juni 2017 11:59, Andy wrote: What you're probably looking for is QRenderCapture: https://doc.qt.io/qt-5/qt3drender-qrendercapture.html I've used it with mixed success to save out images and create a movie using ffmpeg - works fine on macOS, isn't working for me on Windows (see https://bugreports.qt.io/browse/QTBUG-61223 ). I also don't know how to set the resolution other than changing the actual window the scene is being rendered in (maybe there's a way to do it using offscreen rendering but I haven't figured it out). --- Andy Maloney // https://asmaloney.com twitter ~ @asmaloney<https://twitter.com/asmaloney> On Mon, Jun 19, 2017 at 11:24 AM, Christensen, Matias <matias.christen...@flir.com<mailto:matias.christen...@flir.com>> wrote: I have a Qt application with a 3D scene using Qt 3D. What i want is to be able to render a camera at a specific resolution and framerate, and then to be able to access the resulting images in C++ code so i can encode it using h264 and send it to a different process. I am having trouble finding a way to get access to the rendered image, i image this is made difficult as the image never leaves GPU memory and i need to get access to it in main memory. Does anyone have a suggestion on how i might go about doing this? ________________________________ Notice to recipient: This email is meant for only the intended recipient of the transmission, and may be a communication privileged by law, subject to export control restrictions or that otherwise contains proprietary information.
