the main diagonal of colormatrix. For example, the rgba values of a certain pixel are now 255, 128, 64, and 255, while the main diagonal M11-m44 values are 0.8, 0.5,-1, and 0.5, respectively, the new rgba value of this pixel should be: R = r * M11 = 255*0.8 = 204; G = g * m22 = 128*0.5 = 64; B = B * M33 = 64 *-1 = 192; A = A * m44 = 255*0.5 = 128; Is it easy ?! Some beginners may say that the above B value is calculated incorrectly. 64 *-1 should be equal to-64. Yes, 64 is represented as 0xffff

tips](1) construct an undirected graph G and store it with an adjacent matrix.(2) The dijela algorithm is used to calculate the shortest path from the start point to each vertex. The two-dimensional array P [I] [] is used to record the shortest path length.Degrees are stored in a one-dimensional array d [I]; I ranges from 0 ~ 20.(3) the one-dimensional array have [] is used to record the order in which the shortest path appears vertex.(4) output the shortest path and Path Length Based on the st

like metal, Smooth and textured surface. Therefore, reflected light is very useful.By the way, if specular is translated directly, it is a mirror reflection, It means reflection like a mirror. Concept of reflected light The light from the diffuse light emitted from a parallel light source is calculated by the light direction (light vector) and the plane direction (Plane Normal Vector), so as to realize the illumination. The most intense light is the color of the model. On the contrary, the dark

the car plays a key role in reversing, whether through the rearview mirror can determine the distance between the car, we continue to experiment today. The use of the test car for the Great Wall hover, Volvo S60 and Peugeot 206, the choice of these three cars mainly want to test the SUV, sedan, hatchback for the interior mirrors the effect of the control distance is consistent.Experimental methods: We will three vehicles parked in front, from the rearview mirror to observe the position of

UWP development-two-dimensional transformation and three-dimensional transformation, uwp two-dimensional transformation 3D In development, due to some requirements, we may need to perform some translation, scaling, rotation, or even 3D transformations. So let's talk about how to implement these transformations in UWP. I, Two-dimensional transformation: UIElement. RenderTransform A. TranslateTransform, translation: Attribute: X, Y. I believe everyone knows how to use it. I will not talk nonsense

Introduction There are a total of six commandid in the game. Each player has a different division of labor when performing the task, and the equipment and skills they are equipped with have their own strengths. How can they make good use of them based on their strengths, is one of the key factors that can successfully complete the task.Green Beret can be said to be the main character of the game. Basically, he is responsible for most of the assassination and lifting work. Equipped with: pisto

, is specular reflection, that is, like a mirror reflection of the meaning. The concept of reflected lightThe diffuse light emitted from the parallel light source, through the direction of light (light vector) and the direction of the polygon (surface normal vector), to calculate the degree of diffusion of the surface, so as to achieve light. The strongest light is the color of the model, and conversely, where it is not illuminated, it becomes dark.But, like the metal texture, is the performanc
