Bison

ADDON. Version 0.90. Released on 2020-Jan-02. Provides 38 components. Created by bison.la. Features 0 video tutorials.

Bison is a landscape architecture plugin for Grasshopper + Rhino 6. It features tools for terrain mesh creation, analysis, editing, and annotation. It focuses on a continuous workflow from mesh analysis to editing and works to keep components concise and intuitive. The analysis tools include slope and aspect visualization, cut/fill calculations, watershed modeling and more, while the editing components transform the mesh based on curves and points. Bison also includes tools for importing landscape meshes, triangulation, and resampling, as well as components for annotating plans and cutting sections.
