Hi folks, I wish you all a happy new year and best wishes for a winning QGIS3 release!
While working with Z value improvements in QGIS (see [0] ), It became clear that we have some room for 3D - 4D styling. I already have gathered some existing solutions for that: - Use Matplotlib / plotly external tools to display true 3 D objects even if those tools are more "plot" oriented. - Add a panel for vertical cuts like Profile tools and others (we have one using D3js somewhere, another using a true mapcanvas). This gives a true Z value. - couple QGIS with a browser - like horao for true 3D http://oslandia.github.io/horao/ I was wondering if a complementary solution could be to improve expression generator with some iterators that could loop on vertices and generate geometries (so iterators and aggregators such as SQL generate_series / aggregate or window function). We could then imagine to extend current 2.5 D generator to lines, display roof steepness, projects depths with dashed lines and so on. Does that sound like a feasible solution? Again, this will point out a point around advanced SQL engine vs qgis specific expressions but whatever the technical option, I think this could be quite nice. Does that ring any bell to someone working on something similar? All the best!
