Interactive Graphic Statics (IGS) is an open-source research and development platform for computational 2D graphic statics built with COMPAS, a Python-based framework for computational research and collaboration in Architecture, Engineering, and Digital Fabrication.
IGS is based on the theory of Algebraic Graph Statics (AGS) approach to 2D graphic statics. As opposed to procedural construction of reciprocal form and force diagrams used in graphic statics, AGS enables automatic construction of a force diagram from a given form diagram. Using theoretical properties of reciprocal graphs, the geometrical relation between the form and force diagrams is written and computed algebraically. These formulations have been found to be equivalent to the equilibrium equations used in matrix analysis of planar, self-stressed structural systems. This generalized framework to graphic statics provides a robust back-end for a real-time, interactive, and flexible computational implementation of traditional graphic statics.
. Using reciprocal diagrams, RV2 provides an intuitive, fast funicular form-finding method, adopting the same advantages of techniques such as Graphic Statics, but offering a viable extension to three-dimensional problems. Our goal is to share a transparent setup to let you not only create beautiful shapes but also to give you an understanding of the underlying structural principles.
