GRASSHOPPER VB WORKSHOP - Unrolling Surface UNFOLDING CURVED SURFACE // DIGITAL MEDIA CLASS, HARVARD GSD 2013 (re)fabricating tectonic prototypes, Spring 2013, Harvard, GSD - Leyre Asensio Villoria GH version 0.9.0014 woojae sung . woojae.sung@yahoo.com . www.woojsung.com The goal of the definition is to generate curved surfaced approximation with triangles and automate unfolded map of the triangles on to x-y plane for digital fabrication.
Unrolling Surface - http://woojsung.com 3 algorithm design Prior to jump on scripting, very clear definition of the system needs to be thought out step by step. Key things were how to approximate a curved surface using triangulation, and orient individual patches to xy plane for digital fabrication. PROCESS step 01 Build a surface. step 04 Triangulate patches. step 02 Subdivide the surface into series of strips. step 05 Keep a particular order so we can handle points and segments of each triangle easily in scripting. step 03 Subdivide strips into series of patches. step 06 Set a reference point for unrolling. Unrolling Surface - http://woojsung.com 1 Unrolling Surface - http://woojsung.com 2 step 07 Move the reference point along with -y vector and the length of the first segment of the first triangle to get the 2nd point. step 10 This time, use the 2nd segment of the first triangle as a starting point for the next iteration. Use the 3rd point of the first triangle as a reference point of second triangle. Then set a movement vector using the 2nd segment of the flattened first triangle. Based on the length of the 2nd segment of the 2nd triangle and the movement vector, move the reference point. step 08 Move the 2nd point along with y axis in the amount equal to the length of 2nd segment of the first triangle. step 11 Rotate the point using the angle, this time clockwise, to get the 2nd point of the second triangle. 3rd point of the second triangle will be 2nd point of the first flattened triangle. step 09 Rotate 2nd point with the angle between the first and second segments of the first triangle to get the 3rd point. Then using the 3 points, get a closed polyline which represents flatten 1st triangle. step 12 Repeat the process but this time rotate point counter clockwise. Note that when index number of input triangle is 0, or even number or odd number, the process are slightly differ from each other in terms of rotation angle and setting up reference point.
