1. first obtain a set of "" library (Google click), which contains two files: msyh. ttf (common) and msyhbd. ttf (BOLD );
2. Create a sub-directory under the/usr/share/fonts directory, for example, win. The command is as follows:
# Mkdir/usr/share/fonts/win
3. Copy msyh. ttf and msyhbd. ttf to this directory. For example, if the two files are stored in/root/D

CodeSmith is one of the most widely used tools in code generation and has rich template resources and users. Many of my friends used CodeSmith and there are many ready-made templates. NCodeGenerate provides a template Conversion Tool from CodeSmith to NCodeGenerate. It makes it easier for users to switch from CodeSmith to NCodeGenerate. Next we will introduce it.

Zhao GangIntroductionIn a virtual world built on 3D games, virtual scenarios require high fidelity. Among them, 3D terrain fidelity is one of the keys. However, the generation and drawing of 3D terrain requires a huge amount of computing, and the generation of real-world terrain also requires the support of the terrain database, generating Realistic 3D terrain in real time on PCs with limited computing powe

releasing the resource in the destructor of the stack object, the probability of the resource leak is greatly reduced, because the stack object can automatically release the resource, even if the function has an exception.The actual process is this: when a function throws an exception, a so-called stack_unwinding (stack rollback) occurs, that is, the stack expands, because the stack object is naturally present in the stack, so during the stack rollback, the destructor of the stack object is exe
