Web21 hours ago · I was making a basic paint app in SFML and I wanted to let the user draw smooth curves with the cursor. To achieve this effect, I used the C++ code for the centripetal Catmull-Rom spline from wikipedia. I'm not sure what I'm doing wrong but the curve is displayed with a dashed-line effect. I would like to know how I can get a smooth …
