# Chapter 14 Chars, Strings, and Working with Text # Characters In the .NET Framework, characters are always represented in 16-bit Unicode code values, easing the development of global applications. A character is represented with an instance of the System.Char structure (a value type). The...

# Chapter 13 Interfaces # Class and Interface Inheritance In the Microsoft .NET Framework, there is a class called System.Object that defines four public instance methods: ToString , Equals , GetHashCode , and GetType . This class is the root or ultimate base class of all other classes—all classes...

# Chapter 12 Generics Developers who are familiar with object-oriented programming know the benefits it offers. One of the big benefits that make developers extremely productive is code reuse, which is the ability to derive a class that inherits all of the capabilities of a base class. The derived...

# Cameras, Lenses and Light Fields（相机，透镜和光场） # Imaging = Synthesis +...

# Chapter 11 Events In this chapter, I’ll talk about the last kind of member a type can define: events. A type that defines an event member allows the type (or instances of the type) to notify other objects that something special has happened. For example, the Button class offers an event called...

# Chapter 10 Properties # Parameterless Properties Many types define state information that can be retrieved or altered. Frequently, this state information is implemented as field members of the type. For example, here’s a type definition that contains two fields. public sealed class Employee...

# Chapter 9 Parameters # Optional and Named Parameters When designing a method’s parameters, you can assign default values to some of or all the parameters. Then, code that calls these methods can optionally not specify some of the arguments, thereby accepting the default values. In addition, when...

# Chapter 8 Methods # Instance Constructors and Classes (Reference Types) Constructors are special methods that allow an instance of a type to be initialized to a good state. Constructor methods are always called .ctor (for constructor) in a method definition metadata table. When creating an...

# Chapter 7 Constants and Fields # Constants A constant is a symbol that has a never-changing value. When defining a constant symbol, its value must be determinable at compile time. The compiler then saves the constant’s value in the assembly’s metadata. This means that you can define a constant...

# Advanced Topics in Rendering（渲染中的高级主题） # Advanced Light Transport 在高级的光线传播里，我们会说到无偏的和有偏的光线传播方法。无偏光线传播里的代表有双向路径追踪（BDPT）以及 Metropolis 光线传播（MLT）。有偏光线传播会提到光子映射（Photon mapping）以及...
