Ambiguous Project: Cat / Heart

Ambiguous Cylinder: Cat / Heart Pantea Ferdosian George Mason University – MATH 401 Math Through 3D Printing October 6, 2019 For this assignment, we learned about how the ambiguous cylinder works. We know that we basically have to use the mirror symmetry. Even though it seems impossible, but these ambiguous objects are visible to us because of the human “optical illusions”. Many factors come into play when trying to “trick” the eyes to see them, such as the angle that we look at them and the angle of the light that is projected on them. The article by Sugihara beautifully explains the mathematics behind how this works, and I used his article to print my own object as well. I used Mathematica to design my cylinder. First, I graphed the shapes that I needed to intertwine for my print. Then I manipulated the functions of my graph and made a 3D print, to make sure that my object is actually illustrating what I want. At last, using the ParametricPlot3D command, I made a cylinder (as you can see how my code NB file). I used the Ultimaker Printer to print my cylinder which was a bit inconvenient because it took too long to print it. I did not have to use any supports because the curves laid on the cylinder which was its base. My print took around 5 hours to print. Unfortunately, I do not have access to my print yet to upload a picture, but I will do so as soon as I can.
