Vector-based Graphic Static (VGS) is a direct extension of traditional 2D graphic statics to the third dimension. VGS introduced a generalized procedure for the construction of a 3D vector-based force diagram for any given 3D form diagram of a spatial network in static equilibrium. By establishing an interdependency between form and force diagrams, VGS allows users to transform one of the diagrams and evaluate the resulting transformation of the other diagram directly. This property allows for a quick and interactive exploration of possible equilibrium solutions in the early design phase. VGS Tool is implemented as a plug-in for the CAD environment McNeel Rhino/Grasshopper for both Windows and MacOS.
VGS Tool is developed and maintained by:
- Pierluigi D'Acunto Technical University of Munich, Professorship of Structural Design
- Yuchi Shen Southeast University of Nanjing, School of Architecture
- Jean-Philippe Jasienski UCLouvain, Structures & Technologies LAB
- Patrick Ole Ohlbrock ETH Zurich, Chair of Structural Design

VGS Tool makes use of the following libraries:
- the C# implementation of the Boyer-Myrvold algorithm for Planarity Testing by Ondrej Nepozitek - MIT license;
- Math.NET Numerics - MIT license;
- Kangaroo2 by Daniel Piker.
To install VGS Tool, please copy the folder "VGS1.00beta" in the "Libraries" folder of Grasshopper. If you work on Windows, please make sure that the files are unlocked. VGS requires Rhino7 SR13 for Windows or Rhino7 SR13 for MacOS or later.
