Do Over: Ambiguous Object's

For our redo assignment, I decided to go on and visit our most recent assignment, over Ambiguous objects. I felt that my print did not fully capture what I wanted from and really wanted to find one that was better. When coming up with my first one, I went through many different designs, so here I went back to the one that my gut told me would be better but I decided not to listen sadly.

The big change I made was to not construct my object with four different functions for each side. This just caused for confusion when trying to troubleshoot, as well as explaining since it depended on which side you looked at. Moreover, I wanted to drop the regular polygons all together. There are a couple of ways to make really interesting Ambiguous objects out of regular polygons, but that just was not what I wanted to focus on anymore. To me, it did not really go into the theme of objects appears to be different from different observers.

My Do Over:
First Perspective:

Second Perspective:

Overall Shape From Above:


This is my new Ambiguous object! It looks very different from last time, and looks so much interesting in my opinion! Here, both functions were giving the $x$ parameterizaion of just $\cos{x}$ as this gave us some nice curvature. The more interesting part is the $y$ coordinates from both directions! The first perspective was shown with the function: $f(x) = \cos{x} + .25*\sin{x}^2$. This function, from a local perspective, is very similar to the curve $x^2$ which is a bit easier to identify, they you can see this on the object with this almost only curved side!

Now, the part I really liked, was the function for the other perspective. It is given by the function $g(x) = -.5\cos{3*x}*\sin{x}$. On the side that the observer would see this function, it looks like a pair of glasses with these little loops! I thoroughly enjoyed this because the opposite side observer's perspective is nothing like this!

Overall, I am very happy with this object's shape and how it has turned out. I wished I had listened to my gut, but in the end it is better to try something than to never try at all!

Do Over: Integration Over a Region in a Plane

Throughout the semester we have covered a variety of topics and how their mathematical orientation applies to real world scenarios. One topic we discussed, and I would like to revisit, is integration over a region in a plane which involves calculating a double integral. Integrating functions of two variables allows us to calculate the volume under the function in a 3D space. You can see a more in depth description and my previous example in my blog post, https://ukyma391.blogspot.com/2021/09/integration-for-over-regions-in-plane_27.html . I want to revisit this topic because in my previous attempt my volume calculations were incorrect, and my print lacked structural stability. I believed this print and calculation was the topic I could most improve on and wanted to give it another chance. What needed Improvement? The function used previously was f(x) = cos(xy) bounded on [-3,3] x [-1,3]. After solving for the estimated and actual volume, it was difficult to represent in a print...

Minimal Surfaces

Minimum surfaces can be described in many equivalent ways. Today, we are going to focus on minimum surfaces by defining it using curvature. A surface is a minimum surface if and only if the mean curvature at every point is zero. This means that every point on the surface is a saddle point with equal and opposite curvature allowing the smallest surface area possible to form. Curvature helps define a minimal surface by looking at the normal vector. For a surface in R 3 , there is a tangent plane at each point. At each point in the surface, there is a normal vector perpendicular to the tangent plane. Then, we can intersect any plane that contains the normal vector with the surface to get a curve. Therefore, the mean curvature of a surface is defined by the following equation. Where theta is an angle from a starting plane that contains the normal vector. For this week’s project, we will be demonstrating minimum surfaces with a frame and soap bubbles! How It Works Minimum surfac...

Do Over: Ruled Surfaces

Why to choose this project to repeat For the do over project, I would like to choose the ruled surfaces. I don't think my last project was creative, and the 3D printed effect was not very satisfactory. In the previous attempts, all the lines are connected between a straight line and a circle. This connection structure is relatively uncomplicated. The printed model has too many lines, resulting in too dense line arrangement. The gaps between lines are too small, and the final effect is that all the lines are connected into a curved surface, which is far from the effect I expected. What to be improved In this do over project, I would like to improve in two aspects. Firstly, a different ruled surface is chosen. In the previous model, one curve is a unit circle on the \(x-y\) plane, and the ruled surface is a right circular conoid. In this do over project, it is replaced by two border lines. Each borderline is in the shape of an isosceles right triangl...
