Detailed Description▲
The Qt3DRender::QRenderSurfaceSelector can be used to select the surface, where Qt3D renders the content. The surface can either be window surface or offscreen surface. The externalRenderTargetSize is used to specify the actual size of the surface when offscreen surface is used.
When DPI scaling is used by the system, the logical surface size, which is used by mouse events, and the actual 'physical' size of the surface can differ. The surfacePixelRatio is the factor to convert the logical size to the physical size.
