Week 1 Lofting

Creating a space using lofting First using loft in Grasshopper to create a space then use “bake� to change the different forms by using control point in Rhino. Thus a taxonomy of lofted surface has enerated.

2


The results by using the command Populate 3D and Voronoi 3D.

3


The results by using the command Populate Geometry and Octree.

Week 3 Patterning

Created from the command of 3 points arc, then lofting these curves.

8


Created by extruding the arhs in x, y, z - plane.

Week 4 Recursive Algorithms

The results were used the command of scale and trim solid.

10


These forms were created by using the command array with different directions and parameters.

Week 5 Patterning

14


These forms were mainly created by using point charge, merge fields and field line, then bake it by changing the range(graph mapper), graph type and move it toward different vectors.

Week 5 Patterning

These are the results by inputing different images and use different geometries to create a imaged surface. The quality and sharpness of the skin can be modified by change the parameters of the divede surface and the radius of the geometry. The 3D surface is made by using the command loft.

ased on the provided De Young Museum Grasshopper definition. These interesting 3D patterns are mainly lofted by 2 layers of 2D planes, the differences are achieved by inputting different images and geometries, and changing the radiuses. In addition, these patterns are formed by a series of individual parts, which could be easy for fabrication. They also celebrate the technique of pixelation, which is the main technique chosen for our formal experimentations. Speculating on design potential 1. The different surface areas of the selected iterations can have the potential to generate or create green energy. 2. The clustering of repeated forms have the potential to create artificial landscapes such as a earth mound. These landscapes can be use by visitors for recreation and exploration like walking through the Grand Canyon. 3. The tubular and conical shapes can be used as a surface structure to capture wind energy or solar energy.
