Jung Choi: Pepakura

Concept: I got the concept from the game I am playing called Stardew Valley. It is a game where you are a farmer and you work on building it up. In the game, you are able to raise farm animals such as cows and sheep, and I decided to make a bust of a cow as it was the first animal I purchased in the game.

Modeling Techniques: I wanted to use Maya for this project, but decided to try it using Rhino instead.  I used the interpolate on curves tool to create the shape of the head which I extruded to create a solid object. Then, I created a pyramid object then used the split/trim tools to cut a hole on the bottom of the head as well as cutting off the top of the pyramid. I used the blend surface tool between the bottom of the pyramid and the head to create the connecting areas similar to the technique we used for the duck. To create the horns, I exploded a cylinder and the cones, then deleted the bottoms to make openings to which I used the blend surface tool again. Lastly, I used the mesh from NURBS object to create a polygonal mesh, then used reducepolygons to adjust the number of polygons. 

Alec McKay: Waffle Structure

Concept: My design was inspired by other furniture I found online that had been made with waffle structure, such as the above chair. From there I decided to do a sofa, so I did some research into interesting designs for sofas, which was where I got the idea to put a shelf into the back of the couch. I thought the rounded form of both the sofa and the shelf would look good with the layers of waffle structure, and the shelf would add more interest to the back side of the sofa.

Technique: I started with an ellipsoid, and I used another ellipsoid and BooleanDifference to create the seat of the sofa. To create a base, I drew an ellipse curve and used Sweep2 to create a surface connecting it to the ellipsoid above it. Once I had that shape, I created another ellipsoid for the shelving unit. For a flat-bottomed shelf, I used a flat surface to cut the bottom off, and then I used another BooleanDifference to cut that out of the sofa. I also used a large fillet on the edges of the sofa and the shelf so that the arm rests and seat wouldn't be too sharp.

Materials: For my laser cut model, I decided to go with the thin E-Flute cardboard because I thought it would look better for the small scale to have a thinner material, so it would look more similar to what I imagined it would look like at full scale. For my renders, I went with a plastic painted in metallic red for the solid version, and a nice light wood for the waffle structure. A light colored wood was what I thought I could use if I made a full scale version of the waffle structure sofa. I chose a different material for the solid version because the wood didn't look as good in this context, so I went with a bright, shiny metallic plastic.

Jung Choi: Laser Engraving

Concept: When I first heard of this project and Professor Scott showed us the tween curves tool, I knew that I wanted to create some kind of a pattern using that tool. I did not have a specific concept in mind but thought that the tool would allow me to create some interesting patterns. I was very happy with the overall results regarding the pattern as it created something like a swirling circle in the middle with the outside looking almost like flower petals. The piece seems a little busy looking at it from up close, but when you look at it from a bit further away, the lines blend together to create some amusing shapes.

Modeling Techniques: As I had stated before, I wanted to use the tween curve tool for this project. I created a rounded square shaped curve towards the bottom left of a square and then used the tween curve tool. Then, I deleted all other curves but the tweened curve that was one bigger than the rounded square that I had originally. Then, I used the tween curve tool on that curve at the outside square again. After repeating this multiple times with different settings for matchmethods, it gave me the star-like shape and I decided to stick with that shape. I mirrored the star shape across and over so that I would have 4 of them that were towards the 4 different corners of the square. After that I used the curve edit tool> adjust closed curve seam to adjust the seams of the outer square so that it would make the correct effect with the mirrored star curves.

Material: I used a 1/4th inch plywood as I thought it would look interesting with the patterns and the grain of the wood. This proved to be of little use as the grains are hardly noticeable given the dark lines of the engraving and how busy the piece is. The piece itself is 1 foot x 1 foot and I decided to go with those dimensions as it is ultimately in a square shape and I did not want it to be too big.

Jung Choi: Waffle Structure Wave

Concept: The concept I had for the waffle structure project was a wave in the ocean. I got the idea from the Japanese painting, The Great Wave Off Kanagawa, when I saw it somewhere the day I started on the project and thought it would look interesting as a waffle structure with it's curvy and wavy lines.

For modeling techniques, I used the interpolate on curve tool to create the wave-like shape I wanted then extruded it in order to create a sold object. Then I created a cylinder and used the boolean difference tool with the solid to create the concave part at the bottom. Then I used the contour tool to create the curves which I used planar surface tool on to get the surfaces. Then I used the cutribs script and the unroll script to get the slots and lay them out for laser cut. I wanted to create diagonal lines with the contour tool to create a more interesting effect, however, this made the cutmyribs script buggy as it gave an error and not cut the slots when there is a two pronged surface that were connected at one part that branched out to 2 different wings. It would cut slots on the bottom wing but not the top wing, so I had to get contour curves using 90 degree angles.

Material: For the actual structure, I used quarter inch cardboard as it was cheaper. For this project, I wanted the structure to have a slight bulkiness to it as waves are nothing to scoff and dangerous if given proper size which made me choose the thicker cardboard. In my opinion, it turned out fine and still kept the shape of a wave and just made it look like a wave of brown water. If I were to make this without price restraints and had more time to procure materials, I would use a bluish glass with a white/grey glass to create a more ocean water-like color that is see through as I did in keyshot.

Jung Choi: Slots Droplet

Concept: The concept I had in mind for this project was a water droplet hitting the surface of the water. With this concept, I decided to use a lot of round circular shapes in radiate outwards in a symmetrical pattern that gave off a slight feeling of an explosion.

Modeling Techniques: A lot of the slot making was done with the curve boolean tool as well as array polar to get the slots all the way around some of the shapes. For the long shapes, I used two circles then connected them with curves. After which I split the curves in order to trim out the pieces I do not want then joined the open curves together to make a closed curve. The hardest part was planning out the slots so that the top and bottom circles would fit the long slots. After I made the long pieces, I rotated them upwards to see where the slots and what angle they would need to go in order to fit.

Material: For the material I decided to use the eflute cardboard as I did not want it to be too bulky or big since it was supposed to be a water droplet. Thicker material would have made the pattern less noticeable and I believe would have taken away from the theme of the project unless I had made it significantly larger. 

Alec McKay:Prosthetic Accessory: Polygo Modifications

After our critiques on Monday, I decided to make some changes to my prosthetic accessory. While the concept stayed much the same as before, there were some additional modeling techniques and changes to materials.

Modeling Techniques and Changes: Polygo now has a thinner shell design, which I created using an Offset Surface on my existing shape. I also removed one row on the inside of the leg so that the wearer can remove their accessory more easily. To do this I exploded the model and removed some faces before doing the Offset Surface. I also added a clip on the inside wall that can fasten the shell onto the pole of a prosthetic leg. 

Material Changes: To add more visual interest to my prosthetic accessory, I added onto the color palate with a new design. Colors gradating from yellow to red-orange form stripes down the leg. Polygo is made from plastic with a matte paint finish.

Jung Choi 3D Print Solus

I got the inspiration for this 3D print from the Keyblade from the Kingdom Hearts game series. I originally had intended to make something similar that acts as a "sword", but I decided that since the print was going to be small, I decided to go with an actual key. After I decided on going with the key, I wanted it to look like something from a fictional story with special purposes.

I used a lot of extrusions and offsetting of curves to create solid objects for the main body and the decorations. The hardest part was creating the indented curvy decoration on the body of the key. I made the curve, then mirrored it across then projected it onto the body. Then, I used the projected curves to trim out parts that I wanted indented then extruded the curves down then patched the bottom to get the solid indention that I wanted. I used a lot of the joinedge tool as a lot of these pieces would not join with the simple join command. I used filletedge command to fillet the edges so that they would have smooth edges.

 The materials were obviously metal. I wanted it to look like something from a fictional story, something like a magical key to open magical objects or doors so I made it fairly colorful. I gave it a golden body and made a lot of the decorations red and named it Solus as the flare decorations around the head of the key resembled the sun.
