Unsolved How to make opengl offscreen renderer
-
Hi,
I would like to generate pixmap from opengl offscreen renderer.
An extenal library do the rendering; I have modified this library to use QOpenGLContext.
So it works for rendering in QOpenGLWidget.
My purpose is to generate pixmap from opengl rendering offscreen to make icons
in combobox.Thanks,

@Roy44 Hi! As a first read I recommend the documentation page for QOffscreenSurface Class and then the Rendering FBOs in a Thread example. Good luck :-)
