Hello Andrea, just few clarifications in order to see if I correctly understood the issue ... The main difference between solution a and b is that: - in the a case we reproject the crossing side of the geometry by adding an offset to the coordinates and lets say "force" someway the earth to not

Hi Andrea, It's a nice problem. I'd be very interested to help out with algorithms or coding in any way I can because I'm also keen to better my understanding of the rendering system generally, though given my relative ignorance about the internals of the renderer I might be more of a hindrance t
