texture compression

(Dark good director ....) SOURCE one)Because the texture is formed by the repeated appearance of the gray scale distribution in the spatial position, there is a certain gray relation between two pixels separated by a distance in the image space, that is, the spatial correlation characteristic of the gray level in the image. Gray-scale co-occurrence matrix is a common method to describe textures by studying the spatial correlation characteristics of gr

To the users of Photoshop software for detailed analysis of the use of adding light to enhance the image texture processing tutorial. Tutorial Sharing: Often listen to friends around CuO sigh pictures of their own plain, no texture, not beat eyes. And many of my own photos have this problem, after repeated practice and try to figure out, this aspect has a great promotion, some of their own experience to sha

1,Why is it necessary for texture sampling?Texture Filter(Texture filtering ). Our texture is to be attached to the surface of a 3D image.PixelCenter and TextureTexelCenter is not 1 (PixelNot necessarilyTextureSampling center onTexel), And the size is not necessarily the same. When a

Next, we will introduce texture pasters in OpenGL in the following three steps: 0. Declare the data for storing textures: # Define maxtexture 1 gluint texture [maxtexture]; // defines a texture array for storing the subsequent Image Texture Information 1. Introduce BMP bitmap: Aux_rgbimagerec * LoadImage (char * fi

SQL Server focuses on optimization of Stored Procedure performance, data compression, and page compression to improve IO performance (I ). Preface The SQL Server basic series is not over yet, And the last point is not written, and will continue later. Some school friends asked me when I began to write the SQL Server performance series. It may take some time to wait. I have been busy recently, but I will upd

They are basically made using texture packer and contain plist files and png images.If there are few small pictures, you can find the name in plist. If there are hundreds of

1. It is not a complete module, so it does not provide complete code. It only provides ideas and core code. The idea is simple. Maintain a life cycle and the last rendering time for each texture, update the rendering time for each rendering, and traverse the current texture set every certain time (15 seconds) in CCTextureCache, if a texture is not rendered after
