Measured Drawings
DIMENSIONS The measurements were taken using the cutouts, tracing each peice onto paper for an exact replica of the model. As there were many parts, photography did not give adequate results, and thus was not used as a base for the tracing, merely serving as a reference alongside the physical model.

As the dimensions were already in place through the cutouts, it was then simple to halve each dimension to give a 1:2 scale.

Analysis
Not to scale
The parts were joined using slots, forming a series of interlocking planes that gave each other stability and strength. The drawing above shows how the parts slot together. Each panel is shaped differently, but are all flat in an almost 2D way. However, when combined in a system such as this, the 2D element is lost and the overall structure takes on a more three dimensional feel. Through this we are able to easily form quie complex shapes, using only 2d planes and slots.

Digital Model: Process A combination of Rhino, V-Ray, Illustrator and Lightroom was used to create the 3D model of the deer. Rhino formed the base model for the deer, which was then given textures with V-Ray. This was then enhanced with Adobe Photoshop and Lightroom as a final process.
The cutouts were replicated on illustrator before being imported into rhino to extrude. Using the instructions, I was able to easily recreate the full model quickly and accutately.
After creating the model, textures were applied and rendered using V-Ray.
The rendered image was given a white background and cleaned up in Photoshop.
After rendering, the image was imported to lightroom to clean up the colors, matching the original model.
Sketch Process We worked with a series of interlocking sections, creating a frame for someone to wear. After experimenting with this method, we foudn that the pieces were quite rerstrictive and did not allow movement. Additionally, the shape and limited range of pieces were quite restrictive, meaning we had to force some surfaces into forms they were not meant for, or hanging slots off sections without slots.
Sketch Model After building and analysing the model of the deer head, I had a better understanding of the workings and limitations of the section and profiling method. This model demonstrates the ability that is most obvious of section and profiling, which is the strength and rigidity of construction, but also explores new features that I have discovered, such as angular density and the peg joint. With this model, I have decided to approach it in a modular way, creating small units that can be combined in a way as to form almost anything.
Using a peg joint, the modules are able to rotate slightly, eliminating the problem we had with the panels in our previous experiment.
This allows, hypothetically, the ability to wrap around any surface and move to a small extent.
Sketch Model
I decided not to emulate the deer head idea to create shapes, but instead explore the possibilities of the technique.
Sketch Design #1
Ribcage attached to solid back
The ribs protect the person from others who might encroach upon space
Another idea is to mount the ribs onto an arm, allowing free lateral movement, whilst still having an element of crowd control.
Allows tspace within the frame
Able to support the weight of the ribs
The skin is made of quite a rigid material and thus cannot be applied to joints. This applies to the back, not needing to be flexible. The backpack area, being such a strong construction, is well suited to form the centre of the design, having ‘arms’ hanging off it in a ribcage like structure.
Sketch Design #2
Shade with different angles
The nature of the section and profile allows it to take on virtually any shape possible, while varying it’s density. This has been adapted to allow a shade like covering whilst still allowing vision. Along with this is the ability to cover and uncover more or less odf the body according to the needs of personal space.
Sketch Design #3
Peg joints
With this idea, I tried to push the limits of what section and profile can be. The initial idea was the pipe through a plane, which gave rise to the idea of the peg or pin joints. This allows greater flexibility with the wrapping and shaping of surfaces and is more dynamic than the concepts I have been exploring before.
