This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

Computer software technology is an important part of computer technology, because computer is made up of computer software, computer software technology is one of the most concerned area in the computer technology, human today manipulated by the fast development of computer technology. Today's software development tends to be more professional and directionality, as a student whom is studying design, we are often in pursuit of better results and had to use special design software to achieve our goals.

As a design student we must be all familiar with computer 3 dimensional modeling software programs

Today I’m going to discuss the most common known and most frequent used 3 dimensional modeling software program using by not only design student but also many professional architecture designers and jewelry designers, products designers, urban, interior, exterior designers!

Introduction to 3 dimensional modeling:

The so called 3 dimensional, according to the theory, is where the human describes any point in three-dimensional space by means of three coordinates, and we labeled each coordinates, the x coordinate, y coordinate and the z coordinate, where the x coordinate represent left and right of a space, y coordinate represent up and down of a space and z coordinate represent front and back of a space. Thus it concluded the formation of the human stereoscopic vision; the 3 dimensional models are made up of 3 dimensional computer software programs, this to achieve further development of computer technology in variety of industries.

We live in a three-dimensional world; meanwhile, we also live in an informatization era and informatization era which is characterized by computers and digital. Computers are widely used in all industries. Today’s two-dimensional imaged computer would no longer be satisfied, we wanted the computer to be able to express a more reality form and the 3 dimensional modeling software programs can turn this into reality.

The so-called three-dimensional modeling is to use 3 dimensional data to build up existing objects in reality or our imagined objects and reconstructed this objects in computer. It includes the basic information such as the 3D coordinates define the locations of object points, the color of the object surface, Transparency, and texture etc…3 dimensional modeling programs is widely used in various areas, and it provides an Intuition, so 3 dimensional images play an increasingly important role in various fields.

There are many benefits and good reasons of why using 3 dimensional modeling software programs, Firstly, knowing how to use 3 dimensional computer software programs can develop our intelligence to enhance our imagination. During our study life time, Because of our learning system and the environment, we have become less able to produce unique imaginations and less able to elaborate on ideas. Mainly because of the stress we are dealing with each day, we have become uncreative; most of the time we thought copying would be a much simpler way to produce work. However knowing how to use a 3 dimensional modeling software program will fill this vacancy. Secondly, those who know how to use 3 dimensional modeling programs can make abstract graphic image become more intuitive and easy to understand.

Introduction to Rhino 3 dimensional modeling techniques:

Rhino is a powerful three-dimensional software program; it is the first powerful AGLib NURBS modeling technology complete the introduction of the Windows operating system software. Rhino is easy to use, highly flexible and highly accurate modeling tools. Rhino provides almost all tools to be used in the creation of three-dimensional models; it can create any imaginable shape, it can also create any project cannot be completed in reality therefore Rhino is a very powerful 3 dimensional modeling making software program

3 dimensional modeling making is the basic consensus in design making process, without model building, the design idea would be difficult to present. It plays an important part in the design process, because a realistic 3d model is able to reflect the turn quality and the material of the model, it truly made our design ideas becomes real.

Rhino 3 dimensional Modeling discussion:

Modeling making is the basic modeling technique; Today's 3D modeling software programs has its own unique modeling system, modeling method can have many different types, but the main 3 types are the NURBS modeling, Polygon modeling and Patch Modeling.

The rhino software program provides NURBS modeling making, subdivision modeling, Carving Modeling and polygon modeling.

Polygon modeling is the oldest method, and is also the most common method; polygon modeling is the splice of triangles and quadrilaterals, the 3 dimensional model we see on screen is connected by the “face” of polygons,and every “face” are different sizes and orientations, by arrenging these “faces” it complete a very complex 3 dimensional model.

NURBS modeling, Is the most popular modeling method, it offers great flexibility and precision for handling model shapes, is a much more simply and efficient method, it seems everyone can create their 3 dimensional model using the NURBS technology.

Subdivision modeling is also sometimes called the sub modeling, is a way of as it named, it applies subdivision surfaces to create new geometry that has the result of smoothing out geometries, like cubes, pyramids, it produces smooth out render shapes.

Usage of rhino 3D modeling in my project analysis:

To be able to present my imagined design idea to my audience and translate my imagined design idea to reality, at this stage I began to use 3 dimensional software program rhino to build my imagined 3 dimensional model. To build up a 3 dimensional model using rhino, it sometimes take longer times, therefore it would be better for us to choose a final development model to build instead. This way we can concentrate on every details of the model.

When using a 3 dimensional modeling program creating a model, we need to think carefully about its structure, we must have a full understanding of this model, if we are not certain about the model structure then the model that we are going to build would not have a realistic appearance, the details would be missing. Therefore I prefer the quality, not the quantity.

The usage of this 3 dimensional software program rhino has clearly improved the quality of my design, rhino provides models with texture, the textures of the model is actually just an image we see on screen, but after rendering, it can make the model appeared more detailed and more realistic. Compared with wireframe models, it is a higher level technology.

Design process:

1. Collect relevant information, research relevant artworks
2. Design concept: sketch out all usable and suitable ideas
3. Deleting unusable and unsuitable ideas
4. Set up a final development model
5. 3 dimensional modeling making using 3 dimensional software program rhino

Knowing how to use this 3 dimensional programs rhino, I have learned many valuable know ledges, firstly, to have a well presented three-dimensional model is a very important process when creating a design work, without a good 3 dimensional model, it is impossible to complete a good design work. And with the help of this 3 dimensional program rhino, it made design work become smooth, easy and efficient.

Design concept:

My design is called the rain angle, the rain angle was inspired by the weather of Auckland, where the i did a record of the weather of Auckland, i noticed the weather of Auckland was interesting due to the quickly speed change of temperature. The temperature is colder in the morning, the temperature is hotter during lunch time, the temperature rises at lunch time and temperature drop in the late afternoon. i also noticed Auckland is always high in level of humidity, before it rains, humidity usually increases, When it is raining, relative humidity draws near 85%-100%,Auckland average humidity is between 75%-98%, therefore it sums up a conclusion that Auckland rains very frequently, i did a record of Auckland weather by collecting data on the website “the accuweather.com” the red dot represents a day it rained, and base on these red dots, I did a graph that shows the rain data of Auckland! Yet Auckland has unstable temperature, and rains frequently, but it does not effect on wild life’s living, people always say New Zealand is the last paradise for the birds, as New Zealand has more species of flightless birds – both living and extinct – than any other country. i recorded a weather data graph and translated the weather data graph of Auckland into a 3 dimensional model (the rain angle) the flow and the geometry allows the model to collect rain water, rain water will be reused by birds, birds’ uses as a water tank and a bird’s bath! This model is specially designed for birds.
