Bas-relief

Prologue The project was created in 2006. Started from creating a painting made by arbitrarily dropping ink, attempt to build up the ability of observation. By carefully observing the painting , I establish my own standard to distinguish between the lightness and the shade of the painting.

Then I use this new standard to express my interpretation of the difference between the lightness and shade and recreate this painting.

Process First,I represent shade by orthogonal cross line.After decide the standard of density, observe the inked painting`s detail and draw it down. The high density means the darkness in paInting.

Second , I represent shade by contour line. Image the painting as a steep mountain. When you look down this mountain, record the height by circle line . I got to pay more attention on every detail. Third, the second step`s extension. Make a wire model of contour map in second step. The idea is from lampshade. Install a light in the middle of wire model and project a shadow that is identical to the rolled contour map . Steel wire is my main material.

Forth,the second step`s extension.

Observe the contour line,and distributed it into 50 levels.The painting was separated into two half , each half represent opposite view . One represents deep,another one represents height . The handicraft is just like .....................“bas-relief�.

Case Study

Kazuyo Sejima,a japanese architect.

Recently , she gains more and more gaze from international.I am interested to her style : fluid , penetrant .

Unique form and skillfully used glass are two important elements in her architecture.I studied one of her works called Y-House in 1993.From studying the case and making model,I was further acquainted with the architect And the construction.

About Y-House

This building is a detached house located in a small residential area of a provincial city an hour train ride from Tokyo . Many houses in the neighborhood stand on subdivided lots of similar shape . Mild climatic condition of this oceanfront region and urban types of defined condition characteristic of subdivided lots were the two points of emphasis in this project.

northeast–where lighting and ventilation conditions proved to be favorable .

With such layout amid the dense crow of houses in the area , enough distance from adjacent houses would be maintained in the future.

To start with , in order to make the most out of the garden within the limited site area,placed the building in the center of rectangular site , with a large garden on both sides – facing southwest and

What Is Tessellation

Tessellation in 3D

The repeating patterns and the way they repeating form tessellation. By the particular way to associate the patterns we can create any type of tessellation.

What Is Tessellation in “ 3D “ It is the final project of fundamental of architectural design in 2007. I want to translate those repeating patterns to three-dimensional space.

I designed a 3D pattern that developed from original one, and manufactured it . In the step of study, I need to find out the developing potential.

After manufactured it, I tried to associate 3D pattern with another. Finally I created a 3D tessellated space of my own .

Development and Process The spirit of this tessellation is the association between each unit.

So I try to create the study model which can represent it`s spirit.

Another interesting thing in this tessellation is the angle of unit, that makes the unit such like a hook. I`ve tried five different model. Finally, I choose the last one. Because it shows the spirit of association and the potential to generate spacial three-dimensional space.

Projection In order to view the scene on monitor.The first thing is setting objects , camera , and perspective projection . Perspective projection is an important role in simulation , because it lets us discern far and near . Then I have to make sure that the object won`t be too large for the window . And the proper projection coordinate makes scene looks real.

Prologue Point , Line , Plane , three fundamental elements of space. In computer graphic field , people construct 3D model by these three elements , too . In order to get the way of digital modeling and simulate real-life space in digital space . I design a C program that runs 3D model . By these project , I am acquainted with not only the core of many 3D softwares(like MAYA ) , but also the relationship between space and object .

Point – Line – Plane After setting projection ,let`s Implement 3D model . Given a object data that has recorded all the points and every polygon of the object (every polygon is a triangle ). Then,connecting each pair of points in polygon . Now , model Is just like framework . I can rotate it or scale it and look through it . It makes me to associate with architecture`s framework in thinking . In next step , filling up every polygon.This step is as same as connecting the pair of points, because we can use interpolation in geometric mathematic . By this method , we can know evey pair of points` coordinate,so connectinting. All the steps above are just like constructing a building , from framework to wall.

In next step, I give some light and shade for the model , give it “real” color.

Every natural thing`s color is effected by light . So we can feel every thing is not flat , and we can know some information about relationship with nature. To simulate shade, I should set the light source first . There three components effect shade , ambient ,diffuse ,and specular . They effect light`s reflection and absorption . I use two type of shading model , Gouraud and Phong . Both named by the inventor . Their method is the same basically , but Phong makes mor work on every pixel`s sahde,so Phong Shading looks more real.

Suppose we color a sphere model.

We get something like
