最近开始学习图形学了，终于下定决心选择一个自己喜欢，并且希望是适合自己的领域方向了，这也是上周末去见了未鹏后获得的启发。到网上找到一个国外大学的教程，ms还不错的样子，在这里我将记录下我的学习历程。
第一课没多少东西，除了安排有一些书和资料阅读外，教程里也仅仅介绍这门课的课程要求和列举了一些领域术语,很多不是很明白，于是好好google了一把：
(1)Perspective Projection: 透视投影.
(2)Depth Cueing: 景深效果处理(根据离观察者的距离，改变物件的颜色强度和亮度，也就是当物件远离观测者时，降低物件颜色与亮度的一项功能。例如，当一个物体离我们的视线越来越远时，它看起来就会越来越模糊。)
(3)Depth Clipping: 深度裁剪.
(4)Colored Wireframes: 彩色线框显示
(5)Hidden Line Removal：隐藏线消除
(6)Hidden Surface Removal(HSR)：隐藏表面去除. Wikipedia上的解释是：In 3D computer graphics, hidden surface determination (also known as Hidden Surface Removal (HSR), or Visible Surface Determination (VSD) ) is the process used to determine which surfaces and parts of surfaces are not visible from a certain viewpoint.A hidden surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics. The process of hidden surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider.
(7)Per-Polygon Shading：逐多边形投影.
(8)Gouraud Shading: 高洛德着色/高氏着色. Gouraud shading is used to achieve smooth lighting on low-polygon surfaces without the heavy computational requirements of calculating lighting for each pixel.
(9)Specular Reflection: 镜面反射
(10)Phong Shading: Phong shading combines a model for the reflection of light from surfaces with a compatible method of estimating pixel colors using interpolation of surface normals across rasterized polygons.(wikipedia)
这是著色中最为拟真的方式。同时也是最耗计算资源的一种方式。前一个Gouroud Shading是使用三点颜色，而PhoneShading则是用每一个著色点都是经过计算取得, 因此它会大幅降低效能。----但它几乎能表现出接近自然的色泽，在高亮度或色泽变化复杂部份表现特别好。(wordpress中文)
(11)Curved Surfaces: 曲面
(12)Texture Mapping: 纹理映射. Texture mapping is a method for adding detail, surface texture, or colour to a computer-generated graphic or 3D model.(wikipedia)
(13)Displacement Mapping: 位移贴图. Displacement mapping is an alternative computer graphics technique in contrast to bump mapping, normal mapping, and parallax mapping, using a (procedural-) texture- or height map to cause an effect where the actual geometric position of points over the textured surface are displaced, often along the local surface normal, according to the value the texture function evaluates to at each point on the surface.
(14)Reflection Mapping: In computer graphics, reflection mapping is an efficient method of simulating a complex mirroring surface by means of a precomputed texture image. The texture is used to store the image of the environment surrounding the rendered object.
