Readings and lectures

• During Module 2, the limit time forces me to learn and do my

work faster. For Module 2, we need to make the contour model

out first and than make out the basic model according to the

contour model.

• The things I get from the lectures are the method of paneling

and the construction of forms. Rhino really provide a much

efficient way to calculating and setting up patterns into our

model than made our model by hand.

• And about the readings, Scheurer said in his writing that: “What

is obvious in the workshop of a model builder sometimes gets

forgotten when almost infinite digital storage space is at hand:

a perfect model does not contain as much information as

possible, but as little as necessary to describe the properties of

an object unambiguously.” Before reading this article, I am

keeping on thinking that how can I have several patterns on

one model. Now I just want to find out one suitable pattern for

my model.

Summary of natural process

I usually see the poilceman check the fingerprints of the criminals in the films. Because of this, I usually thinking about the fingerprints on our fingers. What

make it become these shapes? Why the fingerprints can change during some time? Why everyone's fingerprints are different? Those questions make me

really interested in fingerprints. Fingerprints can increase the friction when we use our hands to touch things and help us to grasp things tight. The patterns under shoes have the some

function as fingerprints. The fingerprints are natural development during human lives. Gene influence the shape of fingerprints. Because the gene of

everyone are different, so the fingerprints of everyone are different. Actually, fingerprints not only influenced by gene, but also influenced by the around

circumstances. Fingerprints appear when children are about three or four monthes old before born and they will have a little changeduring the growth

period. The shapes of fingerprints won't change after 14 years old.

Fingerprints have three basic types

which are: Arch, Loop and Whorl.

People sometimes use another kind of ways to divide the basic types of

fingerprints. Nowdays, scientists

already can use models to reproduce

the normal fingerprints and the

formation of some uncomplicated rare

fingerprints and they are: Arch, Whorl, Double Loops and Simple Loop.

The imaging structure which has the same shape of fingerprints.

Fig. 4. (a) Ridge formation starts at one or two focal points on the middle of the pad and along

the nail furrow. (b) The region where ridges arise first usually coincides which the core of loops or whorls. (c) Ridges spread over the fingertip, the last areas covered by them are the triradii. (from

Bonnevie (1927a)).

The lights which get from the idea of fingerprints.

Final model

• There was one thing I added in moving from Module one

to Module two and that is the scale. My final model will be

about 30cm in height, 30cm in width and 40cm in length.

And the scale will be 1:10. I plan to hold it on hand for the

natural progress is finger prints.

Contour model

• To make the contour model , I draw the

lines which have 5 mm distance between

each other on a paper. And after that, I

draw the lines on the surface of the model.

Finally, I cut the model into pieces along

the lines.

Digitization

• These pictures show the simplest way to make the 2D

pictures into digital lines. And this method won’t influence

the model too much.

• The two above pictures are the model made from

contour line model. The picture at right is the model which

can also see waves of finger prints from front or right

directions.

Digital model – 2D

• These pictures show the practice

of making 2D model.

• I tried all the options in the setting

command. I think the paneling

skills are really amazing. It just use

the points as the basic points, and

the patterns will appear right after

the command has been made.

Wave panelling

Digital model – 3D

• These pictures show the practice of making 3D

model.

• Before setting up the patterns, I will need to set the

offset points first, and use the original points and

the offset points to make the 3D patterns.

• The diamond 2 is the most one which is I want to

get. When we looking at our finger prints, we can

find out that the finger prints which we think it is a

surface is actually divided into lots of small parts.

Change of the basic model

• After close looking at the paneling model, I want to

change the model. I can see waves when I look at the

model from the top, but not in other direction. And the

lines are too simple. So I want to see waves from other

view like: front and right.

• After changing of the curves, I can see waves in all

directions of my model.

Prototype construction

• For the material of my

lantern, I want to use the

white paper which can

show the light in the

model. And I hope the

model can give a

beautiful shadow.

The final model

• This is my final model

which add the pattern I

get from the natural

progress. And those

pictures are the different

view of the model.
