Bending-active tensile hybrid structures refer to the coupling of bending- and tension-form-active components within a unique and stiffer constructions. The variety of possible shapes applicable to the design of these structures demands new ideas around real-time physics-based simulations for the development of more flexible and interactive design spaces. This paper seeks to contribute to this research by identifying and comparing two main families of generative approaches for form-finding:
more &raquo; ... etric-driven and topology-driven. Fundamental differences of both approaches lie in the management and activation of parameters while the algorithm is running. Geometric-driven approaches are processes where form-found geometries can be variegated through dynamic alterations of metric parameters without affecting initial topological conditions. On the other hand, topologydriven approaches extend the latter by enabling differentiation through interactive adjustments of topological models. In this paper, the core ideas of geometric- and topology-driven approaches are identified and discussed. Alongside to this, the presented study serves to strategically analyse advantages and disadvantages of both approaches as well as the influence that dynamic topological models has when pursuing a solution.
