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.
It is currently in its first beta release. Visit bison.la for a download link and component documentation.
