2D Tiles<\/h2>\n\n\n\n

For my Escher tile, I went with an abstract shape that appealed to me with a regular square tiling. I had a difficult time getting the vertices in the correct places to create a closed shape for the lattice. I had to zoom in a *lot* to get them to align. Initially my shape had more sharp corners, but I found that they caused gapping problems once the offset was applied. Smoothing these corners out greatly improved the fit.<\/p>\n\n\n\n

I chose to do a triangular tiling for my other regular tiling. To generate the tile I created a bottom_left curve like in class as the basis of the lattice, but set the angle to 60 degrees. For each lattice cell, if its horizontal index was even, I moved it halfway along the current<\/strong> index’s x vector and copied the bottom_left curve. If its horizontal index was odd, I moved it halfway along the previous<\/strong> index’s x vector and rotated the curve by -60 degrees.<\/p>\n\n\n

Printed 3D Tiles<\/h2>\n\n\n\n

Initially I read the assignment wrong and created a 3D tile in Rhino. See the Appendix if you want to know more about that. For my Grasshopper generated 3D tile, I chose to use my 2D Escher tile as the base. I used the polygon curve from Large Assignment 2 to create a curve to loft to from my tile. I then inserted code into the tiling block to create copies of the loft curve shifted to match the tiling. From there I created the offset curves and boundary surfaces of my tile and lofted from the edges of the boundary surfaces to the loft curve. As this assignment is already a couple of days late I opted for function over form, getting it done rather than adding design flourishes. Despite the rush to pivot and the struggles get the code working, I like that the tiles look like little volcanos.<\/p>\n\n\n

Surface Morph<\/h2>\n\n\n\n

For the surface morph I used the same tiles from Part 1, though I changed the angle to 90 degrees as their previous angle of 75 was causing the surface morph to be incomplete. I was able to get my parametric vessel code from Large Assignment 2 into a cluster block, however when I connected it to the data dam the surface morph block threw an error about the brep to surface conversion failing. As a result I used a Grasshopper sphere block as my surface. I was able to pretty easily perform the surface morph onto the sphere. The weirdnesses that occur around the poles are really interesting.<\/p>\n\n\n\n

Appendix: 3D Tile Made in Rhino<\/h2>\n\n\n\n

So, I read the assignment wrong and created a 3D tile in Rhino using offset curves baked from Grasshopper. This is the tale of that endeavor.<\/em><\/p>\n\n\n\n

I used my Escher tile from Part 1 as the base of my 3D tile. Initially I made a curve to loft to that was an abstract curvy shape. However, in attempts to get it to loft the way I wanted my tweaks to the loft curve kept getting progressively more fish-shaped, so I decided to go with it and make a fish. In the end I needed multiple loft curves in order to get a suitable wall thickness and viable loft shapes to perform a boolean difference with. I really struggled with both getting the shape I wanted to come out correctly in the boolean difference and with getting the prints to actually tile. What looked fine to me on the screen came out not fitting right on the printer.<\/p>\n\n\n\n
