color, then you can see and the object color or the color of the pattern after the synthesis. The basic idea of computer graphics is to seek such computational processing. How can this process be put into the calculations that the computer is good at? The actual use of vector operations is also. The 3 vectors are used to display the [light vector] in the direction of the light and the [line of sight vector] showing the direction of the line of

the point light source incident light vector Li ).To simulate the highlights, B. T. Phone proposed the phone mirror reflection model:　　　　　　　　　　　　　　　　KS is the normal vector of the object surface, n is the convergence index of the reflected light, and α I is the mirror reflected light direction (RI) and line of sight (v) generated by a light source on the object surface) the angle between cos α I = Ri · V ).To sum up, the formula for calculating the r

the world coordinates, first rotate and then translate. The translation matrix is the inverse matrix of the matrix with the world coordinates of the camera as the translation volume, and the rotation matrix is the transpose matrix of the rotation matrix between the camera and the corresponding axis. For each frame, you only need to manually calculate the transformation matrix once. 4 (optional), 3D cropping: You can crop a body (straight line or polygon) that is not completely inside the video

the contour shape and contour of the object.The list of triangle units contains the data of each independent triangle we want to draw.It is very important to specify the order of each vertex of a triangle. We call it a winding order)The index concept is introduced to solve vertex coincidence.We create a vertex list and an index list)The vertex list contains all independent vertices. The index list contains the indexes pointing to the vertex list. These indexes specify the way in which each vert

From the perspective of the human mind, if the line of sight is blocked by obstacles, obstacles behind is not visible.The following is a case of lol:650) this.width=650; "src=" http://im

To create the right visual hierarchy, you need to understand how our eyes handle information, Uxpin's Chris Bank said. Chris Bank, from uxpin--, a wireframe, prototype app, explains the principles and conventions of creating visual levels in Web UI design. In this free ebook Web UI best Practice, see more than 33 companies in the UI case Analysis report. In addition to being creative, an artist should consider some details, such as writing, color, size, content, and perhaps more importantly, w

-of-sight transmission between the centers in general, a condition that many small cellular sites are unable to meet. The Sub-6ghz non-line-of-sight solution employs a point-to-point architecture that is more suitable for dense underlying networks, but when using a licensed spectrum, narrowband channels severely limit the return capacity, and most sub-6ghz bands are expensive and often do not have spectrum

was approximate, but often good enough.Approxview: A shader that directs the use of line-of-sight direction (such as specular reflection) to turn the line of sight one vertex at a point rather than pixels. This is approximate method, but often can get good enough effect. Halfasview for specular shader types is even faster. Half-vector (halfway between lighting direction and view vector) would be computed a

the same time and so on, we can combine matrix multiplication and addition to mix together. For example, the vector (2,3) is scaled and rotated before the X and Y axes are shifted by 5 and 6 units respectively.The above transformations are called affine transformations (affine transformation)Note: This geometric transformation should be noted in order of operation, and different sequence of operations can bring different results, such as the above example, if we do a pan operation after the sca
