Parametric Modeling of Spider Orb Web Project 1 Objectives: Construct the web based on parametric tools in Grasshopper Apply uniform force (e.g. gravity) to model dynamic of constructed web Project 2 Objectives: Model the localized force on the web (e.g. randomly hitting objects Results on Project 1 Preliminaries Examples on spider orb webs in nature Fig. 1. ( A ) Zilla diodia. ( B ) Zygiella x-notata. ( C ) Araneus diadematus. ( D ) Cyclosa oculata. Secondary frames can be seen in ( A ) to ( D ). Radials with Y-structure can be seen in ( C ). Spiders avoid connecting radials to the frame near an anchor, and close proximity between the ends of contiguous secondary frame threads. Courtesy of Dr. Samuel Zschokke (University of Basel).
