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

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

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

Today most computers have such a feature: CPU integrated core graphics card, plus the computer also equipped with a stand-alone graphics card, such a computer has dual graphics cards, under normal circumstances, dual graphics cards will automatically switch intelligent operation. However, due to the CPU integrated graphics performance is limited, not comparable to the independent graphics, in addition to th

: it is used to store the scene pixel depth of the display area.13. Gamma Correction: Gamma Correction. To compensate for image distortion caused by display deviation, Gamma Correction performs brightness correction on the image.　　 3. Three APIs for 3D graphics　　 Application progam interface: A Software Interface for communication between a 3D application and a 3D video card.　　 1. Direct 3D: it is the inter

The video card is a bridge between the host and the display. After the display signal is processed, the video card must send the signal to the display card through the corresponding interface. The video

is larger, it can not be larger than the power supply fan and CPU fan, here is to look at the brand before going to the video card fan is not good. 8. Software support. DX OpenGL OpenCL PhySX Cuda and other software support-this non-professional users do not have to figure out, DX and OpenGL What, in the civil domain

video card's BIOS. please keep in mind that this procedure can render your card useless if something goes badly wrong. proceed at your own risk, and make a BIOS backup as detailed below. ! Warranty and safety issues!Be aware that flashing your video card BIOS in an attempt to change or upgrade the

will appear color imbalance, lack of color symptoms. Then need to carefully check, graphics card VGA pin, as well as the connection cable to the break, you can quickly find the cause of the failure and eliminate. Second, the graphics card is not compatible The compatibility between computers is a problem that can never be solved. The

problem. To put it simply, the AGP8X specification is incompatible with the old AGP1X/2X mode, while most AGP4X graphics cards are compatible. For the AGP4X slot, the AGP8X video card can be used, but it only works in AGP4X mode. To enhance the compatibility of the video card
