When we use the 'curve to mesh' node in geometry nodes, sometimes we cannot get an ideal results because mesh overlap frequently happens and leads to bad shading on surface, just like this figure:
So I tried to transform the curve into dense pointclouds to get "perfect curve". I did get a much better shading on curve surface (shown below), but this idea was too primitive that cost too much computer performance.
I can't help think about that, is there a way to render a curve just like the way we render pointclouds in blender? Since point cloud can be rendered into perfect spheres, there should be a similar way for curve.
