Flat Path Algorithm

2012-01-27T09:01:45.468Z

This video illustrates a least-cost-path algorithm written in Python and run in Grasshopper.

The algorithm utilizes the networkx python graph calculation library, creating a weighted graph from 3d mesh geometry. In the video three separate paths through shifting terrain are found from three starting points to a shifting destination point. The algorithm includes an input, called "flatness bias" for seeking out routes that are both short and flat as possible.

Drain Algorithm

2012-01-26T23:39:36.632Z

This video illustrates an algorithm for simulating drainage on a surface. The script is written in Python and run in the Grasshopper 3D modeling environment.

In this animation the terrain shifts, and one can see how the drainage paths generated from a series of fixed sources shift to find the slopes and valleys in the terrain.

For each source point, the algorithm:

1. finds the downward sloping direction
2. moves in that direction a designated distance
3. finds the closest point on the surface
4. if this new point is not higher or too close, then
5. it repeats from the new point.

Galapagos Finches Test

A brief test to see if the Finches (Local Code) Component for Grasshopper could be used to export Galapagos results. The answer is yes.

Local Code: Site Design Algorithm

2009-11-23T07:48:46.561Z

using VB.NET scripting in grasshopper, we were able to loop grasshopper definitions on large sets of files. We ran it on a sample batch of 500 different streets, but only 150 are shown in this video. So in the end, we actually have 500 3dm files, referenced geospatially, with 3d geometry on layers for different materials and object types. To make the video, we exported thousands of illustrator files and used applescript and indesign to turn them into 5,100 layered jpegs.
