Kroto is a Rhinoceros3D (www.rhino3d.com/) and Grasshopper(grasshopper3d.com) tool aimed at form-finding membranes. Along with the classical minimal surface problem, it accurately solves external conditions such as cables, uniform pressure and vertical load forces. It can run as a stand-alone RhinoPython script, or as a set of Grasshopper components (with GHPython). It relies upon the membrane form-finding "stress density method", published here: http://www.sciencedirect.com/science/article/pii/S0141029697001089.
Usage examples will be coming soon.
By developping this tool, we hope to provide the 3D-modeling community with a tool that is backed by a physical solution to the membrane form-finding problem. We think that such tools should publish their source code in an effort to offer reliable physical softwares.
Usage examples will be coming soon.
