2.3.3 basic two-dimensional transformation The basic two-dimensional transformations include scaling, rotating, shearing, and translation ). 1) Proportional Transformation Proportional transformation is to enlarge or reduce the horizontal coordinates of any point on the plane by S11 times, and the vertical coordinates by s22 times, that is S is called the proportional transformation matrix. Figure 2.24 shows several examples of proportional transform

Learning HTML does not work, just in the W3school HTML manual under the tutorial to learn the next.What is HTML?HTML refers to the Hypertext Markup Language , which is Hyper Text Markup LanguageHTML is not a programming language, it is a Markup Language (Markup language)Markup language is a set of tag tags (Markup tag)HTML uses tag tags to describe web pagesWe casually open a Web page, the mouse right-click + = View the page source code, you can see the HTML page Markup language.HTML consists of

By default, there are always three files open, standard input (keyboard input), standard output (output to screen), standard error (also output to screen), and their respective file descriptors are 0,1,2. So let's take a look at the differences between the following redirection methods:>/dev/null 2>1In fact, it should be equivalent to this: 1>/dev/null 2

, because the computer is not like human, he will not do subtraction, but in a way to change the subtraction into an addition operation, that is, the so-called complement.Bit operations in JavaAfter the introduction of the complement, the following is the Java bit operation (by means of complement).Example 1 Right-shift operation5>>1,-5>&

The first parameter is the result of the pointer to the D3DXMATRIX struct to save the operation. Parameters 2, 3, and 4 define the eye position, orientation, and upward direction in sequence.
