Reconciling Curves with Rhino Plug-in Tweener

Reconciling curves of different origins is a fundamental part of the designer's toolbox, but it can often result in overlapping or undercutting NURBS curves. Tweener is a Rhino plugin and Grasshopper assembly that solves this problem by guaranteeing smoothness and absence of intersections. It allows to tween either between any number of closed planar curves, or between any two not necessarily closed curves on any given surface.

Tweener curves are drawn interactively by manipulating their boundary conditions, much like how NURBS curves are manipulated by control points, providing a very different perspective on curve modeling. Even though Tweener is ideal for early stage sketches and drawings, it is deeply related to concepts from computer graphics, architectural theory and parametric design.

Join a free webinar focusing on Tweener on August 2, 2023 at 8 a.m. Pacifc Time. This webinar is aimed both at Rhino3D novices and experts. During the broadcast you can familiarize with the core functionality of the Tweener plugin and its history. The demo will cover Tweener's multiple applications, including product design, general illustration, 3D printing, interior design, and landscape.
Bonus topic: you will be able to explore the underlying mathematics of the plugin. You can donwload Tweener for free here.

Presenting the webinar is Mathias Fuchs, a Mathematician with ample experience in applied geometry, statistics and simulation. He's been Senior Researcher at the CODE group, Zaha Hadid Architects, London, and is now an independent programmer specializing in numerical algorithms for geometry and Rhino3D.
