Description: This the second tutorial of the Advanced section. In this tutorial we will examine what Texture Mapping is all about. Textures in 3D Graphics are a way of making something appear rich and complex even though it may not actually be. For example, if we want to create a carpeted floor, all we have to do is draw a polygon that models the floor and map the texture of the carpet on top of it. In this tutorial we will examine how to apply a texture onto a surface. We will cover some important topics such as Mipmapping, Texture Modes, Texture Filtering etc along the way Platform: |

Description: Contourlet变换结合了不可分离的方向滤波组,具备小波所不能表达的多方向特性,能有效捕获自然图像的边缘轮廓信息。本文分析了图像ontourlet系数的统计特征,并利用广义高斯函数对各子带系数层进行建模。将此模型应用于基于VisTex的自建纹理图像库,采用矩匹配估计法,提取模型参数集,运用K2L距离计算图像间的相似度。对800幅纹理图像进行检索,本文方法比传统小波方法的平均检索查准率高出约2％到10％不等。实验结果表明,该方法改进了导向纹理的描述-Transform Contourlet inseparable combination of the direction of filtering group, have not expressed by wavelet multi-directional properties, can effectively capture the edge of natural image contour information. This paper analyzes the image ontourlet coefficient statistical characteristics, and take advantage of the generalized Gaussian function of the sub-band coefficient modeling layer. Based on this model was applied to the self-VisTex texture image database, using moment matching estimation method, extract the model parameters set, K2L use of distance-based similarity between images. Of 800 texture image retrieval, wavelet method than the traditional method of the average retrieval precision by about 2 to 10 range. Experimental results show that the method improves the texture-oriented description of Platform: |

Description: Bilinear filtering is a texture filtering method used to smooth textures when displayed larger or smaller than they actually are.
Most of the time, when drawing a textured shape on the screen, the texture is not displayed exactly as it is stored, without any distortion. Because of this, most pixels will end up needing to use a point on the texture that is between texels, assuming the texels are points (as opposed to, say, squares) in the middle (or on the upper left corner, or anywhere else it does not matter, as long as it is consistent) of their respective cells . Bilinear filtering uses these points to perform bilinear interpolation between the four texels nearest to the point that the pixel represents (in the middle or upper left of the pixel, usually).-Bilinear filtering is a texture filtering method used to smooth textures when displayed larger or smaller than they actually are.
