  1. Starting from this premise, we can easily conceive a height map as a greyscale image, where the intensity of each pixel corresponds to a height

    在這個前提下，我們可以很容易的想到高度圖就是一個灰度圖，每個象素的強度值就為相應的高度值。
  2. 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
  3. The opposite route is also possible, i. e. form a terrain, and its height map, it is possible to create a greyscale image, where each pixel ' s intensity corresponds to a relative height

    相反的路線一樣是可行，例如，從一個地形，它的高度圖，我們可以創建一個灰度圖，讓其每個象素的強度代表相應的高度值。
  4. In the part of image encryption, chaotic map based on kolmogorov flow is used to permute. changing the traditional stream - cipher, new chaotic pseudo - random sequence generator based on the theory of product cipher is presented to substitute the pixel. based on it, linear map to confuse the pixel is presented further, withstanding statistical attack

    在圖像加密方面，採用基於kolmogorovflows的混沌映射對圖像進行置亂，對傳統流加密進行改造，提出了基於乘積密碼理論的新型混沌偽隨機序列發生器完成象素的混淆，並在此基礎上進一步採用線性映射對象素進行擴散以抵抗統計攻擊。
