It also has hulls and minkowski sums, which are powerful once you understand them.
- WillAdams 10mo agoAren't hulls just a direct connection of the edges of two shapes (which could be simulated by a series of duplications) while Minkowski is "just" a matter of putting spheres along the edges of an object to round the straight edges? So, spheres and cylinders and cubes placed, rotated, stretched and placed mathematically.
- bashkiddie 10mo agoA hull requires at minimum one shape and returns a convex shape. A minkowski sum, as far as I understand it, requires a surface and a volume and returns a volume. Example 1: apply hull() to a star shape Example 2: You want to fold a picture (SVG) around a cylinder and make its edges FDM printable by 45 degree overhang, apply a cone to the image
