by the chance of a parametric architecture design conference in Tongji University
i did a report of form-finding of project Shanghai Oriental Sports Center
meanwhile i sort out the grasshopper definition file of the Gymnasium basic geometry
they are formed by booleaning a serier of precisely controlled balls and tubes
here's the link of the file
mind that the files are generated by rhino 4 and grasshopper 0.6.0059
hope that it's useful to you
"I'M THE LINK"
