Project-instruction for students
Look for a machinery in real world (or in printed materials or in the Web) which could be analysed, reconstructed and simulated by means of plane geometry
Observe its function or get information about its function
Get this machinery as digitized picture and load this picture into a DGS which you are working with
Explore ist geometric structur and functionality
Reconstruct the implemented flexible geometric structure by means of DGS and simulate it
Document your dynamic result of reconstruction in the Web.
