Part 1: Escher Tiles:<\/strong><\/p>\n\n\n\n

II encountered a lot of difficulties when working on this part of the project. I started creating many complicated shapes using both Processing and the sketch <\/em>function available in Rhino. As the result, I couldn’t tile the plane using any of the shapes I created. I then tried to create simpler shapes using the sketch <\/em>function available in Rhino first to see what the result looks like before I code it up using Processing.<\/p>\n\n\n\n

I created a few different shapes in Processing. I spent the most time figuring out the math and geometry behind the sI created a few different shapes in Processing. I spent the most time figuring out the math and geometry behind the shapes. I had to calculate the length of each edge as well as the measurement of each angle to draw the best shapes that can tile the plane. I created several shapes to test in Rhino and Grasshopper but the shapes that work the best are the three shapes I have below:<\/p>\n\n\n\n

My second shape (shape 2) requires me to write a little more code to tile the plane. After the shape is imported. I connected to the geometry (geo function), extrude the shape in 3 dimensions (x, y, and z). I then created two more copies of the shape, rotate them based on one point (set at the corner with the smallest angle of the shape) using the Rotate3D function.<\/p>\n\n\n\n

I then merged the three shapes above together and connect them to the bounding box<\/em>. This bounding box is later connected to the Surface Morph<\/em> function to tile the surface.<\/p>\n\n\n\n

Shape 3<\/em> is a bit easier to work on compared to shape 1<\/em> and shape 2<\/em> since the it is based on the square shape.<\/p>\n\n\n\n

he cylindrical surfaces I have in this project were created using this piece of Grasshopper code below. This code allows me to change the height of the cylinder using the number sliders<\/em> and change the shape of the surface using the four points on the Graph Mapper<\/em>. <\/p>\n\n\n\n

This part of the assignment was also very challenging for me. Since the code had to generate complex shapes, my computer wasn’t able to generate\/create the tile or morph the surface several times. Rhino stopped responding and the program was shut down by itself so many times. I lost my code whenever that happened and had to start over again. It was very frustrating. It also took a very long time whenever I tried to use the morph function to tile the plane. Because I had to keep adjusting the number sliders (parameters) to create good base tiling, it was a pain to use the Surface Morph function since it always took a while to run.<\/p>\n\n\n\n

There was an issue with tiling the cylindrical plane and I still cannot figure it out. When I used the Surface Morph <\/em>function to tile my cylindrical plane, the function always tiled more than the actual surface. I have tried to adjust all the parameters, change the shape, width, and height of the plane, as well as check the Bounding Box<\/em> function. However, none of that was able to help me to solve the problem.<\/p>\n\n\n\n

Part 3: 3D Printed Form<\/strong><\/p>\n\n\n\n

My printing process also didn’t go very well. The shape I imported to Cura appeared red in some areas indicating something is missing (like in the figure below). I later tried to fix the shape and most of the red areas disappeared; however, the shape still cannot be printed. I also tried the spiralize <\/em>function in Cura but it still couldn’t solve the problem. <\/p>\n\n\n\n

I then tried the support <\/em>function in Cura and let my printer print for a while. However, it just created a very thick wall outside with many supporting walls around my shape. All the supporting walls are very thick and firm so I don’t think I can remove them from my shape.<\/p>\n\n\n\n

I think the delicate lines couldn’t be printed on my cylindrical surface. So, I went back to the code, and this time, instead of extruding the geometry in three different ways, I connect it to a Boundary <\/em>function and extrude only the Z-direction<\/p>\n\n\n\n

As the result, I was able to make this tiled surface with no holes\/ cut-outs. I later used the move <\/em>tool in Cura and move the shape down on the z-axis in order to get rid of the bottom of the shape since they cannot be printed properly before.<\/p>\n\n\n\n

And here is the result that I got from printing the shape. There’re some interesting textures on the surface but it doesn’t look as interesting as the cut-out style surface.<\/p>\n\n\n\n
