This is my recent "Computer graphics" course practical programming class introduction of the relevant knowledge, mainly want to use MFC C + + drawing, let students realize the graphics related to the programming and simple graphic drawing, at the same time very admire the students imagination, they do really good. I hope this basic article will be of some help to

in the previous article, we talked about MFC's basic functions of drawing graphics, including drawing lines, drawing rectangles, drawing ellipses, and drawing text, while simply understanding the knowledge of graphics by revolving around circles and translating rectangles. I

In computer graphics, there are many ways to represent a real three-dimensional object, such as point cloud, mesh, voxel, curve, etc. this also affects the selection of the drawing primitives when drawing three-dimensional objects, the following is my summary of some of the classification of the drawing technology, I h

How can I draw a CAD drawing in the CAD editor downloaded from my computer? Friends also know that for those who learn CAD, the process of learning CAD is a long process, because they need to continuously practice and operate on the practice, when drawing a drawing, we need to use the CAD editor to draw the

The arithmetic of digital differential analysis drawing line in computer graphicsModern computer graphics, our programmers often encounter drawing programming problems, and now there are a lot of drawing API, in other words, the graphical API is very rich, from TC graphic to

There is no classmate used a period of time of the computer, suddenly found that "start/All Programs/accessories" under the "paint" disappeared, although not commonly used, but really need to use when still very catch. I have just come up with similar problems, so we can share the solution, hoping to help us to catch the urgent. Method One: In the control Panel there is an option to add a remo

calculated:How to promote to Integer algorithm?The answer is to let e=d-0.5e0=-0.5Once per cycle: E = e+kif (e>0) then E = e-1E+k This is still a floating-point additionBecause k= y/xBecause of the notation of the error term, you can replace E with e*2* x:e0=-xOnce per cycle: E = e+2 yif (e>0) Then E = e-2 xThis has become an integer additionAlgorithm steps:The algorithm steps are:1. Enter the ends of the line with P 0 (x 0,y 0) and P 1 (x 1,y 1).2. Calculate the initial values x, Y, e=-X, x=x

Thinking logic of computer programs (27), thinking 27 In this section, we will continue to discuss the packaging class, mainly the Integer class. Next we will introduce the Character class. Long is similar to Integer, so we will not discuss it separately. Other classes are basically introduced and will not be described again. What else do I need to introduce to a simple Integer? It has some binary operation

Thinking logic of computer programs (26) and thinking 26 Packaging Java has eight basic types, each of which has a corresponding packaging class. What is the packaging class? It is a class that contains an instance variable and stores the value of the corresponding basic type. This class generally has some static methods, static variables, and instance methods to facilitate data operations. In Java, the bas

value of the initial decision parameter number isCalculates the increment of subsequent decision parameters toThe pixel points generated along this line path are shown in Figure 3.12.The implementation of the Bresenham line algorithm with slope 0 #include by considering the symmetry between the eight and four regions of the XY plane, the Bresenham algorithm is universal for any slope segment. For a line segment with a positive slope and greater than 1.0, as long as the rules for the X and Y dir

vain. So here are some tips for beginners if the computer doesn't respond when you're doing something important, do not go to the mouse, try to close the window, because the program has no response has been explained that the computer's internal program is not smooth, and then to point the mouse is equivalent to increase the burden of the computer, is tantamount to worse, you say no response to the program

Thinking logic of computer programs (29) and thinking 29 This section describes the Character encapsulation class Character. String operations are probably the most common operations in computer programs. Java indicates that the String class is String. This section describes String in detail. The basic usage of strings

I. Basic concepts of BIOS When talking about bios, have you been concerned about it? In fact, whenever you press the power key on the chassis, it will really work for you. So what is bios? The book gave us a definition: "BIOS is short for Basic Input-Output System (Basic Input-Output System). It is responsible for initializing, setting, and testing various system hardware at startup, to ensure that the system works properly. If the hardware is abnormal, stop working immediately and report the er
