While a linear loft between two profiles would leave the quantization entirely to the user, intermediary slices could be generated using constraints or parameters for each loft node. We could potentially offer different kinds of transitions between profiles.Steiner points could be added to reduce triangulation artifacts. Some kind of tension minimization may be best. How to associate boundary points between two profiles.polygon() with 3D points could possibly be used for this. For certain applications, the profiles being lofted must be nonplanar.To be able to discretize shape or movement formulas, it's possible to use for loops with loft, e.g.: The idea of loft is that it successively morphs one shape into the next. Loft is also called skin in the discussions. splitting up a sweep into multiple non-intersecting sub-sweeps and let CGAL do the union job). How do we handle self-intersecting extrusions? Ideally, we should guarantee a manifold result, but we might need to postpone this guarantee and let the user be responsible for this (by e.g.We could postpone this variant to a later point in time. This requires us to extend the OpenSCAD language with function values. The slices could be located either uniformly along the path or dependent on local curvature.
