Visari to Grasshopper
Click image above 2 watch video Autodesk is developing a new program, ‘Vasari’, which allows for quick and efficient wind and heat gain analysis. A common problem is pulling information across from these types of programs, like EcoTect, into a designers environment like Rhino and Grasshopper or 3D Studio. Without a proper SDK, or the understanding thereof, it is a frustrating and irritating process.
RHINO: GRASSHOPPER DEFINITIONS - RHINO / GH
This definition was developed for my final thesis project to generate a louver system based on functional requirements within the building. The performance was then tested in Ecotect. A large part of my thesis design involved invertible arena seating with many moving parts.

Grasshopper: Parametric CurvesThis module covers the basic parametric properties of curves along with common grasshopper methods for evaluating and dividing curves. ARCH 598 Summer 2011information >> n-formations FABRICS // LATTICES // FIELDSThis course is designed to introduce and explore computational design, algorithmic thinking, and digital manufacturing–both: the larger ramifications that emerging digital technologies and ideas are having architectural theory via readings, discussions, presentations; and the practical application of these ideas and tools through a series of hands-on, iterative modeling and fabrication assignments.

Folded Shell Structure by Liane Ee Making Sheet Architecture Folding turns flat sheet into doubly curved shell Folding adds structural stiffness to a surface and can be a potential construction system for large span structures with complex geometry.
Grasshopper « Geometricmind
This grasshopper definition is to create a Hyperbolic tower with helix partition. 01 concept There are two features in this definition, first one is to use ‘function’ component to create geometry. The concept is explained in the image above. Basically, there are doughnut like floors through the whole tower, each has the same area. This was enabled by ‘function 2′ component that inputs are the area of the outer circles and the floor area you want.

Grasshopper (Explicit History)
Same Area Voronoi using Galapagos I have been quite fascinated by the recent development of Galapagos for Grasshopper. This is a simple example of its application set up to solve for a 10-point voronoi division within a user-defined boundary where all the parts are divided as equally as possible in terms of their areas. I ran this with an initial population of a hundred for 200 generations. The results are not 100% perfect, but very close (which is the nature of an evolutionary solver I believe). Gradient Patterns

Grasshopper At times, (especially when producing animations) it may be useful to link several controlling variables to a single slider. Adding color by customizing the default Grasshopper preview in Rhino is a way to build more dynamic representations by adding a level of detail and information overlay to the geometry on screen. Builds on the Reactive Geometry post. Methods introduced include isolating data from short lists, forming relationships between Rhino and GH geometries, and assuming surface curvature by faceting with planar surfaces.

Generative Algorithms: Lindenmayer-System (L-System)
An L-system or Lindenmayer system is a parallel rewriting system, namely a variant of a formal grammar (a set of rules and symbols), most famously used to model the growth processes of plant development, but also able to model the morphology of a variety of organisms. L-systems can also be used to generate self-similar fractals such as iterated function systems. L-systems were introduced and developed in 1968 by the Hungarian theoretical biologist and botanist from the University of Utrecht, Aristid Lindenmayer (1925–1989).
