reading a computer book, you can scan text in sight. This is not a quick reading, which is much faster than quick reading. Then, use the line of sight to filter out sensitive words and find the key words. If you are interested or do not understand the words, stop and take a look. In addition, existing development experience is also crucial. For example, when I read the ADO database development book, I dire

A standalone game Teleglitch uses a deceptive technique to simulate a cone of view, with the following effects:The blogger looked at the tipsActually, the line of sight shadows aren ' t do with perspective. They is just black polygons extruded from the walls away from the player. The math is similar to black 3d walls extruding towards the camera and if you really look at them, they aren ' t.The principle and cartoon rendering extrude Edge is the same,

, in accordance with the NDC to get the screen coordinates, and then according to the center point screen coordinates and screen center point coordinates interpolation, get offset, in accordance with the Pan method in the Oribitcontrols to update the camera position.　　This approach ultimately fails because the camera may make various transformations, so the offset of the screen coordinates is not linearly aligned with the position in the 3d world coordinate system. The final idea is that we now

-Surface shader will not be rendered until the soft vegetation is turned on. interpolateview-Calculates the line of sight direction in the vertex shader and interpolates it instead of the pixel shader. This makes the pixel shader faster, but consumes one more texture interpolator. halfasview-Pass the half-direction vector, not the line of sight direction vector, to the light function. Half-direction

After dinner to go for a walk, see the downstairs children holding the ipad stamp to delimit, sigh now the child is really happy. And do not say that silk foot food nutrition surplus, in the entertainment, education means, also unprecedented rich. The popularity of tablets and touch devices, while entertaining, has also contributed to the evolution of current interactive devices. By watching the kids play the ipad compared to how we used to play games as a kid, we can find that from simple child

The network media needs to serve the immediate needs of the user rather than the mirror, and you need to study your users rather than show off your talent. 5, landing Then introduce a content page design term: "Landing". Where is the landing point of the user's view? In the first three screens, the user browsing more patie

. 　　Z Mode The browse mode of Z mode is that the content of the Web page is not a text page. Whether or not it's a menu bar, or just a top-down reading habit from left to right, the user first focuses on the content in the horizontal direction of the page header. When the line of sight arrives at the bottom, follow the custom pattern from left to right, repeat and scan the bottom of the page. Z mode can be applied to almost

You may have heard the saying that good fonts are invisible, but more accurately, they should be good fonts that make reading behavior effortless. When a line of sight is passing by, it is a leap forward, which we call a glance. You're not reading letters, not even words, but images of a part of the text, and the brain will fill in what it expects. If beyond the brain's expectation, it will prompt the eye back to verify that the hypothesis is correct

to the bottom of the screen, do not hesitate to put the search bar above (the following image). This is the main screen layout of Android, very wrong. (Here want to explain is: in fact, the design law is still valid, the error is unreasonable to follow the design law, piling up caused the space layout problem) (To solve the problem of limited space) be sure to avoid piling controls in the touch interface, especially the bottom area. Unfortunately, this means Android app has to put

At this point, the 30-sample eye movement data are sufficient to illustrate usability problems. 　X, eye movement data analysis parameters applicable to all cases Common eye Movements Report, the total without the user's view of the browsing track, stay time and other aspects of the comparison, it seems that the value of eye movement here on the draw. When analyzing data, we are susceptible

The common way of page expression is part of the entire Web interaction design method: Designers in the design of the page, should be on the page to establish a number of visual levels, to guide the user's visual focus. Draw the attention of the user to the most important elements, and then steer the line of sight to other, less important, information. This makes it easy for users to quickly and easily find their own needs, better completion of rea

we going to be quick? This set of fonts is called Fast (Swift) and is used in typesetting of text that requires quick access to information, emphasizing not elegance, but economy and speed. Please read the above paragraph line by row (this passage has no practical meaning), feel the speed of the line of sight movement, and then read the paragraph with Sabon Next before reading the text, compare these two times which read fast? Why does Swift speed

paint like a Jedi when I was painting, but I still wanted to show that he was dangerous and explosive. I don't think the current light is up to the above requirements, but I don't want to start again. The shadow effect of the image at the moment is useful on the active layer because you can change the position of the shadow as easily as it erases a part of a layer. So I use a shadow that covers the eye of the character to make the thriller in the movie so that I don't have to change any part o

down. What if there is a right div? Isn't the browser stuck? So we will think of a way to delete all the divs that have disappeared out of sight, so that the page can maintain a certain number of nodes, but delete and add nodes frequently, it will bring about a lot of performance overhead. In this case, you can use the metadata mode. The metadata mode provides shared objects for reuse. For example, if only 10 divs can be displayed on the page, the 10
