What's the most elegant way to get a nice. rounded corner in a 2D shape, where the sharp corners are? I tried bevel on points (on light green points), bevel on edges (the dark green edges), but the results aren't smooth. The best results I got was with qLibs "Rounded corners" OTL, plus some smoothing (on the right), but it still took some post-processing.

I usually calculate the smooth minimum of a grid towards both curves.

You could also look into blurring with weights.

Thanks, both work. I measured the cook time, the weights seem ~1.5 x slower. I prefer to keep the exact points from the original shapes (outside of the rounded area) for 100% sharp corners, but it's easy to do with nearpoint, snap etc
