| summary |
This paper concerns the current discourse on computer-aided design tools for architectural design. There are drawbacks of purely analytic design tools which hinder a system-level, end-effect oriented ideation. For instance, most freeform quadrilateral meshes are fully constrained and therefore not capable of folding. They can only fold under special circumstances – when their geometry satisfi es the conditions of over-constrained kinematics. However, such intent of folding cannot be captured using simple modeling based on parameters and constraints. Furthermore, algorithmization of mesh kinematics using formulas is infl exible, it cannot handle topological variations, and it inhibits the interactive control of the model. In this paper, a fuzzy logic algorithm which uses a goal-oriented, human-like reasoning to control the parametric model is proposed. The algorithm applies easily observable behaviors of the geometry to adjust the selected patches until the entire shell can be folded. The algorithm relies on designer-observable characteristics of motion rather than on formulaic representations. Such approach directs the designers’ focus on the desired outcome while avoiding the drawbacks of analytic modeling of complex kinematics. |
