In today’s drawing class, we taught methods of drawing basic transformations by hand. Mirror was one interesting subject of that. However, then I opened Grasshopper and Rhino to test the effects of curved mirror planes. Unfortunately I realized that there is already a curved mirror component in Grasshopper :( Here is the Grasshopper definition: [GHX: 0.9.0061] This might be one of the simpliest ways of introducing generative deformations for design geometry.
