the upper-left corner. In OpenGL, the object surface coordinates range from 1 to 1. The coordinate system origin is in the center position. the process of OpenGL video display Knowledge of textures has been documented in the article "simplest AV playback example 4:direct3d playback RGB (via texture)". The concept of textures in

We know that there are already several kinds of graphics cards, for example, independent graphics, core graphics, as well as integrated graphics, different graphics card positioning is different, a lot of friends for the core graphics, motherboard integrated graphics and independent graphics lack of knowledge, do not know what the difference between the three, the following article in the rookie friend for a brief summary, Hope to help you. The diffe

other device of the same screen, we can use software emulation to zoom in, but it can be slow and unbearable. With mixed mode scaling, you need to create an OpenGL ES texture and render the picture (320x240) onto the GL quadrilateral. Textures will be scaled to fit the screen size (1024x768) and your game performance will be significantly improved. From the perspective of implementation, this process can be described as follows: Initialize the

The difference between a standalone video card and an integrated video card explains one: sharpness is the same, is in the game when the screen is to the core of the graphics card to deal with these images, CPU will need to display the information to the graphics

This behavior also occurs with the reinstallation system. After testing the BIOS setup problem, the picture in Device Manager is as follows: Solution

First, try to modify the DNS address 1. Because the ipad is likely to have an automatic IP address may be a bit of a problem, we can try to change DNS to solve the video card problem, click on the ipad "settings" 2. Find the "Wireless LAN" in the ipad then we click on the exclamation point next to the wireless network we use 3. Access to the WiFi Setup Panel we click on DNS 4. Then the DNS 114.1

Graphics card is the key to determine the performance of a computer game hardware, the importance of even as much as the CPU. So, when choosing a video card, how do you look at the performance of the graphics card? Generally speaking, we can get a comprehensive understanding through the graphics

Method One, 1. In the Computer "Start" Menu we click "Run" in the pop-up run window we enter the "DxDiag" command, and then return as shown in the picture. 2. Now you'll find that you have a "DirectX Diagnostics Tool" Panel open. 3. Now we click on "System" in the DirectX Diagnostics tool to see a lot of information about the system, such as: What systems, manufacturers, processors, memory, and so on. 4. Of course, we can also click "Show" in "DirectX Diagnostics Tool" to see the detai

1 Preface Every year after the Spring Festival, the university begins, many students return to campus, the market also ushered in the traditional sales season. For friends who have been involved in computer hardware for a long time, in the face of the market many graphics cards, they are very difficult to distinguish one by one, and in the purchase of graphics, it will inevitably fall into some misunderstandings: "High frequency graphics card is fas

tablet size (1024x768) or any other device with the same screen, we can use software simulation to scale, but it will be slow and intolerable. To scale in a hybrid mode, you need to create an OpenGL ES texture and render the image (320x240) to the GL quadrilateral.Textures are scaled to the appropriate display size (1024x768) through hardware, significantly improving game performance.From the implementation perspective, this process can be described
