I took a picture of my mouth and iterated the transformation in Photoshop. Then I traced it in Inkscape. Then I imported to Illustrator in order to import into Rhino (because Rhino surprisingly does .ai but not .svg). I chose a spiral because I find spirals tend read the same way in 3D as they do in 2D, so this sort of graffiti stencil-type image would also make sense as a physical object.

This is a trace of my hands making a bull or goat shadow puppet. I used the same workflow of camera->PS->Inkscape->Illustrator->Rhino. The two pieces correspond to my two hands. They are meant to be cut out of slightly differently-colored acrylic in order to read as a contiguous silhouette while still hinting at the origin of the shape.

1. Study all examples listed in the “Digital Fabrication and Art Practice” post; spend about 5 to 10 minutes with each work and its artist, and possibly more with the exhibitions. Be prepared to explain, discuss, analyze and critique each project and its relationship to the topics of this course;
2. Find another example of digital fabrication within the context of contemporary art practice (one that is not in the above post) and be prepared to explain, discuss, analyze and critique each project and its relationship to the topics of this course.  Post an entry to this blog with links, images and a description of the project (please choose the appropriate categories for the posting)

This is a simple geometric box that I created by drawing a sphere in Rhino then changing it to a mesh with a very small number of polygons.

I created planes from the mesh and unrolled the planes to form a template. Then I added in tabs so that I could fold it up and glue it together.

Algorithmic design for laser cutting:

Other design based on an object from life:

I used my large, red scarf as the basis for this design. I really like it.

Design two boxes with the following design specifications:

ONE

• a single material with the following properties
• Length + Width + Height less then 18 inches
• no hardware necessary
• visually communicates its purpose

• made of two different materials
• Length + Width + Height less then 18 inches
• composed of “Skeleton” and “Skin”

Two designs, in Rhino, to be laser cut (keep it under 24″ x 18″)

• Algorithmic: Start with a basic shape, repeat a process systematically (e.g. the repeated diminution exercise in class).  Make the necessary adjustments in the model to allow it to be laser cut.
• Based on the real world: take a top-down (bird’s eye) perspective photograph of a real-world object, import the image into “Top” transport of rhino, and model it with lines and curves; make the necessary adjustments in the model to allow it to be laser cut.
• In both exercises, consider what material you would use and why.
• Upload both models to Black board before Monday morning’s class.

NB 1.  When there’s a length or an option, you can type it (if you can)
NB 2.  Use a two button mouse, use a big/second screen (if you can)

drawing: (you can either click to draw or type the dimensions you want)

• points
• circle
• line
• rec
• polyline
• curve

measurements:

• length: length of line or curve
• distance: distance between two points
• area: area of a surface

geometric transformation:

• orient: good when the thing you’re moving is asymmetric/sided/chiral
• offset: scale and copy
• scale1D: good for resizing lines
• scale2D: good for resizing flat shapes
• scale (you can indicate with numbers the scaling factor)
• move
• copy
• arraycrv: orient and copy

2d-3d-2d:

• loft: make connecting surface between two lines/curves
• extrude
• make2d: create 2d shape of selected surface, according to current view
• unrollSrf: turn a volume into flat components
• dupBorders: produce curve from boundary of a surface

cutting/expanding:

• explode
• split: divides a line/curve/surface at a center point/line/intersective-surf/curv
• trim: split + delete
• extend
• rebuild

make many out of one:

• divide: dividing lines/curves into equal parts
• rebuild: either turn cuves into lines or make ugly curves pretty curves

housekeeping/getting-around:

• layer: show layers window (use many layers!)
• show/hide
• setPt
• zs: zoom set, show you just the selected object in the active transport
• join: make one curve out of many segements
• group
