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.

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)).

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 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

Tri-basic panelling

Diamond panelling

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.

Digital model – 3D

Window panelling • •

Pyramid 1 panelling

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.
