Since the original book of the OpenGL ES 2.0 Programming Guide does not provide the sample code for the 12th chapter, the code in the book only mentions the key steps, and most of the Web is an example of the Android/ios version, most of which are based on OpenGL or OpenGL ES 3.0, in order to deepen understanding, so that their own implementation of a C language version, hoping to help the same like OpenGL
Events (C # programming guide) when other classes or objects are concerned, classes or objects can notify them through events. The class for sending (or triggering) events is called "publisher", and the class for receiving (or processing) events is called "subscription ". In typical C # windows forms or web applications, you can subscribe to events caused by cont

C language Stack Getting Started Guide In the computer field, the stack is a concept that can not be ignored, we write the C language program is basically used. But for a lot of beginners, the stack is a very vague concept. Stack: A data structure, a place to store when the program is running, which may be the knowledge of many beginners, because I used to think
not be in the other header file in front of the declaration, try not to public;3. As far as possible without global functions and global variables, consider scope and namespace constraints, as far as possible to form a single compilation unit;4. Global variables in multiple threads (with static member variables) do not use class types (including STL containers) to avoid bugs caused by ambiguous behavior.The use of scopes, in addition to name pollution, readability, mainly to reduce the coupling

What is a pointer? 2. pointer definition and Operation 3. pointer and array "Love and hate" 4. distinguish between function pointers and pointer Functions 5. pointer and Structure 6.

is the most convenient. For example, when you When the same method is called in the class (as in LINQ to SQL), the parameter type is WhereThe call looks similar. In the previous example, note that the delegate signature has an implicit type input parameter of the int type and returns the int type. A Lambda expression can be converted to a delegate of this type because it also has an input parameter (X) and a compiler can implicitly convert the return value to an int type. (Type inference will

The indexer (C # programming guide) in the interface can be declared on the interface (C # reference. The accessors of the interface indexer are different from those of the class indexer in the following aspects: the interface accessors do not use modifiers. The interface accessor has no body. Therefore, the accessors are used to indicate whether the indexer is r

, protected, or proprietary. This can achieve the purpose of information hiding, that is, to let the class only expose what must be known to the outside world, and hide everything else.There are two main ways to layout a class:(1) write the private type of data in front, and write the function of the public type behind.Programmers who use this layout argue that the design of the class is "data-centric" and focuses on the internal structure of the class.(2) write the function of the public type i
