Hi, your idea is great! Howerve, I found that gl_Positions are used for interpolation before normalized by gl_Position.w, which is a non-linear behavior. I suppose they should be normalized by w and then interpolated to get bezier points.
Thanks for your sharing!

Hi,

I think @xxm52 is right. When I calculate depth normalization in B (before bezier curve interpolation), my result is much better.

Thanks for your help also :)
