insolar louver system

ted — Thu, 29 Oct 2009 19:00:48 +0000

This definition extends the GH powercopy to be parametrically associated with the solar geometry obtained through the insolar radiation algorithm. It is part of a larger series related to the idea of Environmental Parametrics.

GH powercopy

ted — Thu, 29 Oct 2009 17:24:13 +0000

This definition is inspired by David Fano’s Parametric Truss tutorial, which can be found here. This version extends the approach to the 3 dimensions by utilizing the normal vector of the surface. Please complete Fano’s tutorial before view this one.

insolar component population

ted — Thu, 29 Oct 2009 17:21:10 +0000

This is a follow up tutorial that shows the whole process of using the insolar definitions (analemma, day and current time) in conjunction with the mesh component population definition. It is a 2 step process and make use of box morph. It is part of a larger series related to the idea of Environmental Parametrics.

component population on mesh

ted — Thu, 29 Oct 2009 17:18:17 +0000

This file populates a set of geometric components (examples with 4 or 8 components included) on a colored mesh. The color information is a way to embed external data into the geometry and give you instant feedback about the perfomance. The data can come from Ecotect analysis, the sun system which is available here, or any other analysis software. Meshes do need to be quads.

image mapping on mesh

ted — Thu, 29 Oct 2009 17:13:41 +0000

This example shows how to map images onto NURBS surfaces and output as mesh. This is one part of a larger series that uses the color space method of component population, which as a conceptual framework, I will name this Environmental Parametrics here. It uses the RGB space as a way to to embed external data to create a dialogue with geometry, thus giving it an overall geometric intelligence

multipoint attractor on mesh

ted — Thu, 29 Oct 2009 17:09:16 +0000

This example file shows how to use 3 points (or as many as you want) to create a color mapping that can be used with the component population tutorial. As a conceptual framework, I will name this Environmental Parametrics here. It uses the RGB space as a way to to embed external data to create a dialogue with geometry, thus giving it an overall geometric intelligence

a simple construction of a geodesic sphere in a hex grid. the construction method is based on a icosahedron.

stereographic projection

ted — Tue, 29 Sep 2009 14:46:52 +0000

The stereographic projection was originally known as the Planisphere projection, known to Hipparchus and Ptolemy and was often used to create celestial charts in ancient time.

This example inflates any CONVEX polyhedra into a sphere and projects its vertices and edges onto a horizontal plane from the “north pole”.

parametric brick tiling

ted — Tue, 29 Sep 2009 07:35:06 +0000

This example file takes and the accompanying video takes you through the process of creating a simple running bond “brick” tiling on any NURBS surfaces. The example file has an extra set of nodes allowing you to control the amount of rotation each brick will receive to create an overall patterning effect. This rotation process is not part of the video tutorial.

mapping projections

ted — Fri, 25 Sep 2009 16:21:46 +0000

A simple example file I use as a teaching tool. The setup starts with a 1 point perspectival system that cast a series on rays through a curve object onto a picture plane. Mapping coordinate is then recorded and remapped onto another NURBS surface of another shape. It introduces the concept of global coordinates vs local coordinates.
