| 9. | 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
