bevelslui

Bevelslui is a hypothetical term used in discussions of computer-aided design and 3D modeling to denote a method of applying bevels with adaptive control for curved edges. It is not a standardized concept in major CAD or rendering manuals, and the definition varies among practitioners.

Definition and scope: Bevelslui refers to edge processing that adapts bevel width and profile to local surface curvature and edge length, aiming to preserve smooth transitions and consistent edge geometry across complex geometries. Unlike fixed-bevel operations, bevelslui seeks a continuous change in bevel parameters along an edge segment.

Algorithms and implementation: Conceptually, approaches include curvature-based adaptive beveling, distance-based ramping, and field-guided beveling using normal or curvature fields. Implementations may operate per-vertex, per-edge, or per-face and may rely on normals, curvature estimates, and tolerance settings.

Applications: The technique is discussed in the context of visual aesthetics, manufacturability for 3D printing, and toolpath planning for CNC machining, where gradual transitions can reduce stress concentrations and improve finish.

History and usage: The term does not have a single, authoritative definition and is mainly encountered in informal online discussions or experimental software. Because of that, practitioners may associate different parameterizations with the name. See also: bevel, chamfer, fillet, edge flow.
