Text/figure DecemberOnline worms are used to running QQ, MSN, FlashGet, and other programs every day. Do you think it is troublesome to repeat the same action day after day? Therefore, using a program to enable multiple processors is definitely a good choice, which can save a lot of time and choose how many seconds to run. It is really good. However, this tool is a shared software. If you do not register it, you can only run it several times. Therefor

At the beginning of the life cycle of the hello program, it is a high-level C program, because when in this form, it can be understood by people. However, to run the hello. C program on the system, each c statement must be converted into a series of low-level machine language commands by other programs. These commands are packed in a format called executable object program and stored as binary disk files. The target program is also called an executabl

Write in frontThen the previous section, when the development environment was set up, of course, we wanted to write 3D applications right away. But we also need some patience, because OpenGL is a low-level API, so we have a little more basic knowledge, before we begin to draw 3D graphics, we will be familiar with the concepts and processes of modern OpenGL by drawing a triangular program. In this section you can learn how to compile, link, and use met

G.drawrect (10,10,60,90); G.fillrect (90,10,60,90); G.copyarea (40,50,60,70,-20,80); G.copyarea (110,50,60,60,10,80); The example applet overrides the update () method, clearing only the circle block, not clearing the text, and the window displays a constantly moving red square.

In the previous article, I showed how to connect the x server and how to create a window. Creating a window is fundamental to writing GUI programs. There are two other key points in GUI programming, one is event handling and the other is drawing in Windows. In this article, you will show how to use XCB to draw in a window.Let's look at a sample code and how it works, with the following code:1#include 2#incl

sprites from the same texture. Group_commandcan be used to wrap multiple Rendercommand collections, and each rendercommand in Group_command does not participate in global ordering. Quad_command Quadcommand is used to draw one or more rectangular regions, each of which is part of a texture, such as sprites, Tiles, Particlesystemquad. A Quadcommand contains the following 4 parts: Textureid:opengl es draws the textures used. Shader Program: Shader programs
