have at least some basic knowledge of algebra, trigonometry and linear algebra, which is necessary to be mastered as a master of graphic software; If you want to become a computer graphics research worker, then the study of mathematics will be "live to old, learn old." The important thing is that you will be more likely to enjoy the beauty of math from the previously seemingly boring mathematics to the actual application process. As you continue to s

If you can agree that the world is mainly composed of dummies, we should be able to accept the following series of less rigorous Inferences: Things that are fashionable usually belong to the world of dummies; => Non-dummies will certainly do some uncommon things; => To break away from the dummies sequence, you ne

If XHTML and CSS are object-oriented .. The sun should have risen from the north. However, everything should look at the problem with the idea of OO, And we can barely pull together. In fact, some people proposed OO-style as early as a few years ago, but they cannot find it. So how OO? As we all know, CSS can be used as an example:. G_G {* xxxxxx *}. We can use it like XHTML and CSS to be object-oriented .. The sun should have risen from the north. However, everything should look at the problem

light conditions, but also automatically select the appropriate exposure combination.22. superfocal LengthBecause the rear depth of the lens is relatively large, it is said that the distance for clear imaging after focus is the superfocal length. A dummies camera generally uses the superfocal length, and uses the short focal lens to clearly imaging the scenes after a certain distance, saving focus, generally, low-end

Animation (Animation)Animation means changing over time, especially in visual changes, including changes in position, shape, and so on. The motion basically shows the change of the position of the object with time, and the form basically shows the change of size, color, transparency, shape and so on.The image is played at 24 frames per second and is most easily viewed as a moving image. Slower than this, the human eye will feel incoherent because of the long pause time. The human eye seems unabl

Back to "flash Basic Theory Class-Catalog" This chapter introduces a special technique, known as the coordinate rotation. As its name implies, it is the object that rotates its coordinates around a point, and the rotation of the coordinates is essential in making some very interesting effects. Among them is the question that has been discussed in the Flash world for many years: "How do you bounce on an incline?" "And I'll give you one answer." Another program with coordinate rotation is the in

this data is organized in a very good way. If you need to further optimize the reading speed, you can completely reverse the normalization of the data, the course information as an inline document in the "Classes" field of the student document, so that only one query to get the student's curriculum information: {"_id": ObjectId ("..."),"Name":"John Doe""Classes": [{"Class": "trigonometry", "credites": 3, "204"}, { "classes": " Physics ", " credites

" method. 21. Two programmers are chatting: "I met a hot girl yesterday. I took her home and immediately started to kiss with hunger. She sat down on my keyboard and then ......" "Do you have a computer at home? What is the CPU model ?" 22. Why do programmers like UNIX: unzip, strip, touch, finger, grep, mount, fsck, more, yes, fsck, umount, sleep? 23.

span, we re-enter national highway 224 before the town of nansheng. Looking at the miles buried along the National Highway, the relentless and excited shouted, "224 kilometers have not been missed !", In the past, she wanted to take a picture on national highway 224 at the 224 km logo. After crawling a small slope, I finally found the logo, but the idiot has rushed over. Only four of us stayed to take a photo. I have also done this on national highway 325 in Beihai, Guangxi, See figure . After

windows. The problem is that even if you can do it, you may not do it. This is the so-called force of culture. In theory, you can read and study anywhere, but the most efficient place is the classroom and study. On the comfortable sofa in the living room, you can pick up the TV remote control.So in my own experience, it is better for a programmer to use a Unix-like operating system. It can help you improve your level and work efficiency in your daily life. This is a bit similar to photography.

. megui is very powerful and is the best choice for converting high-quality AVC videos. There are many containers that can be output, now, you can directly output MP4 files that can be played by PSP. (For a long time, this type of Universal Video suppression tool cannot directly extract videos that can be played by PSP) Unfortunately, this software does not seem to have a Chinese version. Why don't we recommend some previous dummies for videos with xf
