演算法的提出證明了將圖像繪制的研究方法引入幾何繪制領域的可行性，演算法通用性好，對場景模型與對象模型均能夠依據不同的投影關系進行圖像的坐標變換，同時，演算法還能夠依據光照特性對象素點顏色值進行變換。Gules coordinate has on behalf of place appear on the market the average of the company, maize coordinate is in the average of the industry on behalf of this
紅色坐標代表所有上市公司的平均值，黃色坐標代表該股所在行業的平均值。Directly painting textures on top of 3d objects in 3d perspective viewport is a new issue of human - computer interface ( hci ). this paper presents a method to solve this issue. it converts the position information of the texture pixels of texture map into color information ， and then transfers both the coordinates and the color of texture pixels into screen through texture mapping at the same time. only is the color information of texture pixels converted into illumination by calculating the normal and the angle of ray incidence of the screen pixel in the method. the texture coordinates are firstly converted into the color information by generating another texture map ， which is called information map whose pixels ' color represents the coordinates information. and then the corresponding texture coordinates are mapped into screen reference frame by texture mapping and stored into information buffer for later use. so we can obtain the texture coordinates of screen pixels correspondingly by decoding from information buffer. after optimizing ， we can paint textures on top of 3d objects in 3d perspective viewport in real time. the paper also gives some examples and related definitions of using additional information of 2d texture map for 3d graph generating
針對三維逶視投影視圖中對三維物體表面紋理直接進行噴繪，以獲得復雜紋理圖這一計算機圖形交互技術這一新問題，研究了一種將紋理圖的象素位置信息轉換成彩色信息，然後利用紋理映射將紋理坐標連同該點上的顏色值一起傳遞到與屏幕象素對應的可見點上的方法，其中顏色值依該點處的入射光線方向和表面法向被進一步轉換為光強值，而紋理坐標則被解碼后還原成與該可見點對應的紋理坐標，被存入信息緩沖器中，供以後使用，通過解碼，可根據屏幕點直接得到對應紋理象素點的坐標，經過演算法優化，實現了對三維物體表面紋理的實時噴繪；同時闡述了在三維圖象生成技術中使用附加紋理信息的應用實例以及相關定義From the point cloud surfaces, multi - layered geometry images are created which can represent the original models accurately very much. the compounded geometry image representation of point cloud surfaces, is also based on the former transform method, where the difference lies : take one of coordinates as the gray value and another two as location respectively, three different geometry images can be created. three gray images are combined into a compounded color image
點雲曲面的復合圖象表示方法，首先把點雲曲面中點的笛卡爾坐轉換為球面極坐標，分別把球面極坐標[ r ， ， ]中的一個坐標轉換為象素的灰度值，另外兩個量轉換為該象素的坐標，這樣就可以得到三幅不同的圖象，把這三幅灰度圖象分別對應到彩色圖象的r ， g ， b中去，就組合成為一幅復合彩色圖象。Color quality of a color stimulus definable by its chromaticity coordinates, or by its dominant ( or complementary ) wavelength and its excitation purity taken together
可由色度坐標或結合其主要（或補充）波長和相應的激發純度來定義的色刺激值。On this basis, the color characteristic in this system we extract is : a 72 bit vector of one dimension by statistical color histogram in hsv space ; a set of color average of sub - images and a set of position of sub - images by dividing the original image and using statistic information of pixels " color ; a set of representative color of an image using a suitable cluster algorithm in the hsl space
基於這方面的考慮，提取圖像的顏色特徵有：在hsv顏色模型空間中進行顏色直方圖統計得到一個72bit一維矢量；將圖像在縱橫方向進行平均分割，以各個分割快中像素的色彩平均值和分割塊在圖像中的位置作為圖像的像素坐標空間特徵；在hsl顏色模型空間，通過適當的聚類分析演算法提取出能夠代表圖像顏色特徵的代表色集。Each stage s texture coordinate index must be set to its default value. the default index for each stage is equal to the stage index
當使用頂點著色器進行呈現時，必須將每個貼圖層的紋理坐標索引設為各自的默認值。Sets the pixel at the specified coordinates to the specified color
設置指定坐標的像素為指定的顏色值。分享友人
