So, what is a developable surface? Good question. It is possible to create non-developable (or doubly-curved) surfaces with lattice hinges by expanding the pattern, but this is only possible with flexible materials (metals and plastics) and is a much larger conversation about geometry (check out Daniel Piker's blog). If you don't have Rhino, maybe this information could be useful for developing your own technique or could be a starting point for other experiments.įor more information on the science behind lattice hinges, I still highly recommend reading the articles on Deffered Procrastination here įor the purpose of this instructable, I will assume we are working with a rigid material with minimal flexibility and plasticity (such as wood, paper, acrylic, etc.) so we will only be concerned with developable surfaces. If you use Rhino, you can download Grasshopper for free and use the file I've provided. To do this, I am using Rhino and Grasshopper. This instructable goes a bit more in-depth about a technique for applying a pattern based on actual surface curvature. I have been inspired by conversations with my good friends Arthur Mamou-Mani and Andrei Jipa (who created an amazing lattice hinge installation for BuroHappold Engineering seen here ) to further explore the concept of parameterizing lattice patterns. What I did accomplish was how to apply a pattern to a curved surface, but the approach was basically a crude approximation. I had previously experimented with a variety of lattice hinge patterns to find the optimal geometry for flexibility in a quest for a pattern that bends in multiple directions. This instructable is a continuation of my previous experiments with kerf bending (also known as lattice hinges) seen here
