This is the note of CPT205 Week5. This week is mainly about Viewing and Projection.

• Concepts of viewing and projections
• Types and advantages/disadvantages of projection
• 3D viewing co-ordinate parameters
• Orthogonal projection
• Frustum perspective projection
• OpenGL functions
• Sample code

This is the note of CPT205 Week5 Transformation Pipeline and Geometric Transformations 转换管道和几何转换

• Transformation pipeline 转换管道
• Standard transformations
  • Translation 翻译
  • Rotation 旋转
  • Scaling 扩展
  • Reflection 反射
  • Shearing 剪切
• Homogeneous co-ordinate transformation matrices 齐次坐标变换矩阵
• Composite (arbitrary) transformation matrices from simple transformations 复合(任意)变换矩阵由简单变换
• OpenGL functions for transformations 转换的OpenGL函数

This’s week we will discuss about Geometric Primitives. (几何图元)
Applications Packages Tools –> API Library –> Algorithms Techniques

1. Graphics Primitives
   • Points
   • Lines
   • Polygons 多边形
2. Line Algorithms
   • Digital Differential Analyser (DDA)
   • Bresenham Algorithm
   • Circles
   • Antialiasing 反锯齿
3. Polygon Fill 多边形填充
4. Graphics Primitives with OpenGL
   • glBegin(GL_POINTS); glBegin(GL_LINES)
   • glBegin(GL_POLYGON); glBEgin(GL_QUAD)

This’s the note of CPT205 W2.

因为矩阵的知识快忘光了，所以矩阵的部分写的比较多。

This is the note of CPT205(Computer Graphics).
包括了Lecture还有Lab的内容，是在预习笔记上增加了一些内容。
