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 -
Because adopt the long - range control technology, consider it with the systematic compatibility of the original display screen, input software software adopt and use but former software that producer offer realize the long - range way to control totally, this needs two computers to realize this function, the first computer is used in editor ' s content of showing and transmitted data to the second computer, the second computer is used for receiving the first datum sent of data and carrying on the buffer memory of data

With regard to the flow regulation of the best - effort traffic, the controllable traffic in high speed computer communication networks, the present paper proposes a novel control theoretic approach that designs a proportional - integrative ( pi ) controller based on multi - rate sampling for congestion controlling. based on the traffic model of a single node and on system stability criterion, it is shown that this pi controller can regulate the source rate on the basis of the knowledge of buffer occupancy of the destination node in such a manner that the congestion - controlled network is asymptotically stable without oscillation in terms of the buffer occupancy of the destionation node ; and the steady value of queue length is consistent with the specified threshold value
