Part 1 – Escher Tiling<\/h2>\n\n\n\n

I decided to use Processing to create this part of the assignment. I started by using the shodor site (http:\/\/www.shodor.org\/interactivate\/activities\/Tessellate\/) to create a rectangular tessellation. I basically just tried to make as assymetrical and ‘wild’ looking of a shape as possible and ended up with this design:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I then used the ‘information’ tab on the website to replicate this in Processing, using the turtle’s goToPoint function to go from vertex to vertex:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Note that the y-coordinate changes are inverted for Processing’s coordinate system.<\/figcaption><\/figure>\n\n\n\n

Then it was just a matter of tessellating it across the pane, and making it more visually appealing. I ended up going with a black background and randomizing the line color for each tile:<\/p>\n\n\n\n

Part 2 – 3D Tiling Across a Surface<\/h2>\n\n\n\n

I used the same method to create a 3d tile in Grasshopper. I started with a triangular tile with a simple transformation:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"
The basic tile ported into Rhino with 1mm height<\/figcaption><\/figure>\n\n\n\n

Then, using more python script blocks and ‘Solid Difference’, I cut out two triangles from this tile. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

After that, it was just a matter of tiling it. I had to change the tiling code from lecture quite a bit to create a better tiling for this shape, but I got it working eventually.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Then, I surface morphed it across 3 surfaces:<\/p>\n\n\n\n

\"\"
z = 30*(x^2 + y^2), z scale = 1<\/figcaption><\/figure>\n\n\n\n
\"\"
z = x^3 + sin(y^2), z scale = 12<\/figcaption><\/figure>\n\n\n\n
\"\"
Default sphere, radius of 60<\/figcaption><\/figure>\n\n\n\n
\"\"

Part 3 – 3D Printed Form<\/h2>\n\n\n\n

I tried printing the first 2 designs a couple times, first with no support then with limited support, but they all failed at some point in the printing process. I really like the spherical design and I want to print it out, but it needs a lot of support structures and is currently in the process of a very long print. <\/p>\n\n\n\n

Code<\/h2>\n\n\n\n
