Re-mesh of any given tri-mesh into a quad-only mesh. This is achieved by integrating two conjugated vector fields.
The family of conjugated vector fields comes from a non-linear interpolation of two vector fields: one aligned to the principal curvatures and another with the principal stress direction.
This results in a tradeoff which brings edges aligned to the principal stress curves and faces being almost planar.
This application makes beam optimization easy, by interfacing itself with a FE software and changing beams’ cross-sections according to their utilization factor, until a certain goal is reached.
“Freeform Geometries in Wood Construction” is the title of a diploma thesis conducted by Marko Tomicic at the Technical University of Vienna under the supervision of Prof. Dr. Helmut Pottmann, which was published in October of 2013. The thesis explores the possibilities of rationalization for complex architectural geometries in order to simplify the building process, especially the building with wood.
This four day workshop was held in Salerno in September 2013 with Daniel Piker and Gennaro Senatore as tutors. The goal was to design and build a reciprocal frame system from a freeform surface, helped by the new kangaroo tools Daniel was developing. You can have an idea of what a reciprocal frame system is reading my article on Nexorade, bear in mind that traditionally these structure were conceived to work only with compression shear forces, but negative curved surfaces inevitably bring to traction shear forces, that’s why it was necessary to use plastic strings to keep the assembly together.
This is the paper I presented at the International Association for Shell and spatial Structures 2013. Also you can find the full paper here.
This is the poster I presented at the AAG14, trying to summarize my Master’s Thesis project.
Dodo is a plugin for Grasshopper where I’m collecting scientific tools useful for computational designers. You can find the plugin comprehensive of some examples here and the full manual here. If you have any questions, ideas to implement or insults, do not hesitate to contact me!
