Hi, The constructor is private because you aren’t intended to create the dynamic replica directly, you must get it from a node. The object won’t be valid until it receives an initial state from a source in another node, so the nodes must be connected together. See: https://code.woboq.org/qt5

A shapefile is a bunch of geometry with attributes. Your coastline is likely just a simple line with each point so easy to convert into a line for drawing. The gdal library can be used to read shapefiles as well as a ton of other vector file formats. Might also be other simpler C++ libraries for

I do have .shp files for the coastlines - perhaps I could convert those to something I could use? If I can get vector data, how would I go about utilizing it? I played around a bit with loading different image files, but so far the performance has been unacceptable - the entire app locks up for

Hi guys, I got it working using Qt3DQuickWindow, but when I tried to integrate the same framegraph in my actual implementation (offscreen rendering to FBO similar to Scene3D’s code) the texture handles come back as 0.  Attached is my standalone example, modified to use Scene3D to illustrate
