Interactive LED Circuit

 




The principle of this assignment is actually not difficult, but the main difficulty is that it is difficult to understand these points in class, and some details in it may take me half a day to understand in my native language.

This device can be used for an interactive figure with 3 different colored leds built into its head, and then the sensors are placed in the figure's treasure. The audience can change the color of the led by rotating the treasure, which is used to reflect the change of the doll's mood.

This is a hollow vase, and I want its surface to look full of design. In fact, I initially planned to create panels through a graphic, but various issues arose, such as the deformation that occurred when they were combined. The most important issue was that they were surprisingly ugly. So I won't show it. Later, in my spare time, I discovered a very cool thing online, which is to use pull points to influence graphics. So I used Voronoi to create irregular polygons Each polygon is scaled with its own center point, but still requires a coefficient to do so, so I set this coefficient to the value output by the Pull point. The distance output by the Pull point is the shortest distance value from all points to the curve. The farther away the polygon is from the curve, the larger the distance value, and the smaller the scale factor. So I need a control coefficient, and I used multiplication to generate a new scaling coefficient. But there is still a problem with the scaling factor being

 You may not understand what this is, but what I want to say is that it is a modern style bench.... This is its original appearance： I think it's really suitable to be placed in the park. Cutting it open gave him a stronger sense of design, which is what I have always wanted to do. Let's see the final effect. I tried using two different materials, walnut and oak Finally, I would like to say that this bench looks very appealing to my taste, but unfortunately it's a bit buttocks draining.

 I created an elevated structure in architectural design for this project, in which I applied the knowledge learned in the first class. Then spread it out to establish the faces of the polygon Comparing and controlling the size of polygons using size values Finally, combine them together
