About Wire-frame model

Wire-frame model

        A wire frame model is a visual presentation of a three dimensional or physical object used in 3D computer graphics. It is created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using straight lines or curves. The object is projected onto the computer screen by drawing lines at the location of each edge.

About Computer simulation

Computer simulation

 

 

 

 

          A computer simulation, a computer model, or a computational model is a computer program, or network of computers, that attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of mathematical modeling of many natural systems in physics (computational physics), astrophysics, chemistry and biology, human systems in economics, psychology, and social science and in the process of engineering new technology, to gain insight into the operation of those.

          電腦模擬，計算機模型，或計算模型是一種計算機程序(computer program)，或網絡的計算機，試圖模擬抽象的特定系統。電腦模擬已經成為一個常用數學建模，自然系統的物理學（計算物理），天體物理學，化學和生物學，人體系統的經濟學，心理學，社會科學和工程的過程中新技術，能夠深入了解這些行動。

 

 

       

About Vector Graphic

About Vector Graphic


Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical equations, to represent images in computer graphics.

向量圖型是計算機圖學( computer graphics)中，用點(points)，線( lines)，曲線(curves)或多邊形(polygon)等基於數學方程式的幾何圖元(primitives)所表示的。

About 3D computer graphics

surface: http://en.wikipedia.org/wiki/3D_computer_graphics
3D computer graphics (in contrast to 2D computer graphics) are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing.
Cartesian = 笛卡爾或卡氏幾何

三維電腦圖形（相對於二維電腦圖形(2D computer graphics)），是於電腦內部記憶體儲了幾何資料(geometric data)的三維表示，用於計算和繪製二維影像。此類圖片可能會後顯示或實時觀看。

About Sub-D

Sub-D (Subdivision)
source:http://en.wikipedia.org/wiki/Subdivision_surface

Subdivision surface是3D計算機圖學的一個領域，藉由粗糙的線性多邊形網格的平滑呈現出來。經過遞歸的模型細分平滑計算過程後粗糙的表面會呈現平滑的面，是以逼近的方式產生接近平滑的表面。
---Wikipedia
A subdivision surface, in the field of 3D computer graphics, is a method of representing a smooth surface via the specification of a coarser piecewise linear polygon mesh. The smooth surface can be calculated from the coarse mesh as the limit of a recursive process of subdividing each polygonal face into smaller faces that better approximate the smooth surface.
