Task 1

Software used: Rhinoceros 6, Grasshopper, Galapagos

Tools Used:

The session was the introduction of genetic algorithm in grasshopper. It began with the explanation on what is genetic algorithm and how it works in grasshopper. This followed by two small exercises to understand it by making a script in grasshopper.

Task 2

Software used: Rhinoceros 6, Grasshopper, Galapagos

Tools Used: Curve, Divide Curve, Interpolate, Loft, Rectangular, Move, Area, Rotate, Vector XYZ, Project, Deconstruct, Sort list, List Length, Subtraction, Galapagos

The exercise was to find and locate the steepest patch on the wide contour site. For this a site contour site was generated and polycurve on it. Using Galapagos the fitness criteria was feed into it and the evaluation was done.

Task 3

Software used: Rhinoceros 6, Grasshopper, Honeybee, Galapagos

Tools Used: Curve, Divide Curve, Interpolate, Loft, Rectangular, Move, Area, Rotate, Vector XYZ, Project, Deconstruct, Sort list, List Length, Subtraction, Galapagos

This exercise was to generate best possible view at point on the selected site using Galapagos. For this, few building blocks were created and the best possible view was generated from a chosen point on the site.
