import OSM

OpenStreetMap data for Lausanne I was testing out the Elk plugin for Grasshopper some time ago (back when only the initial realease was available and found the ability to import data from OpenStreetMap incredibly useful. Not only is this an opensource database, but it’s global coverage is pretty thorough saving the trouble of trying … Continue reading

Mesh Import

Rhino to Processing This sketch expands on the earlier Half-Edge Mesh sketch, demonstrating how to generate a large HEM class from text files containing the vertex positions and the vertex indices for each face as comma separated lists. (To generate these .txt files from Rhino via Rhinoscript see this post.) The difference between this sketch … Continue reading

Mesh Export

Rhino to Processing In a previous post I covered the implementation of a Half-Edged Mesh as a class in Processing. In that definition, however, both the vertex coordinates and face indexing were hard-coded in the body of the script (Lines 8-9). This may be acceptable for a mesh with only 16 faces, but for most … Continue reading

Wind Impact Simulation:

Feasibility study of renewable energy sources. Ten years of monthly average wind directions and speed (via Wolfram), in reaction with topographic variations simulated in Processing for visual analysis using the Anar+ library and a custom built half-edge mesh class. Darkness of the line indicates proximity to ground. Red squares mark wind impact with and deflection … Continue reading
