Web11 de abr. de 2024 · Both of them are NURBS, the only difference is in control points. Why the tessellation on the edge looks great in 2.jpg and terrible in 1.jpg? The same for inner … Web1 de abr. de 2016 · First you need to generate a grid of individual points on the surface. If your surface parameters go between 0 and 1, let's say that you generate points every 0.05. In that way you will have a grid of 200x200 = 40000 points. (from your post I get that you have already done this) Then you can draw your surface using GL_QUADS, for every …
