IG-Mesh
ADDON. Version 0.3.0. Released on 31-Jul-2023. Provides 26 components. Created by Zhao Ma. Features 0 video tutorials.
IG-Mesh is a grasshopper plugin for both low-level and advanced mesh processing. The library features tools for extracting both low-level information (e.g. vertex, edge, face relationship) and high-level properties (e.g. isolines, quad-planarization) that many mesh processing plugins do not provide. IG-Mesh is developed for the general architecture, design, and fabrication community, hoping to fill the gap of mesh operations in any design-to-fabrication pipelines. The goal is to resolve the long-lasting pain of interactive mesh processing on the Rhino & Grasshopper platform.
