VC绘图/游戏简易教程--1：创建新项目[本期目标] 学会在VC 里面创建项目，并写简单的程序。

VC 写程序要有项目的概念，一个项目可以有多个 .cpp 文件，多个项目构成一个工作区。

先记住这两个英文单词吧：∙Workspace: 工作区∙Project: 项目现在开始创建一个新项目。

∙VC6 创建新项目请参考这个视频：/news/View.aspx?id=65∙VC2008 创建新项目请参考：/news/View.aspx?id=85∙VC2010 与VC2008 相似。

看明白后，自己动手建立项目试试，并输入以下代码：#include <stdio.h>void main(){printf("Hello World!");}尤其是之前用tc 的同学，请务必创建新项目试一试。

成功执行后，会看到屏幕上有“Hello World!”几个字符。

然后，再重新输入以下代码试试（无需理解代码含义）：#include <graphics.h>#include <conio.h>void main(){initgraph(640, 480);line(200, 240, 440, 240);line(320, 120, 320, 360);getch();closegraph();}执行后应该可以看到屏幕正中央有一个十字。

看到该十字后，本节课结束。

VC绘图/游戏简易教程--2：简单绘图，学习单步执行[本期目标]学会简单绘图，并学会简单调试。

先看看上一课的代码，我加上了注释#include <graphics.h> // 绘图库头文件，绘图语句需要#include <conio.h> // 控制台输入输出头文件，getch()语句需要void main(){initgraph(640, 480); // 初始化640x480的绘图屏幕line(200, 240, 440, 240); // 画线(200,240) - (440,240)line(320, 120, 320, 360); // 画线(320,120) - (320,360)getch(); // 按任意键closegraph(); // 关闭绘图屏幕}解释一下：1. 创建的绘图屏幕640x480，表示横向有640个点，纵向有480个点。

利用VC编写简单的绘图程序

利用VC编写简单的绘图程序上机实验环境亦可选择Microsoft Visual C++〔以下简称VC〕。

VC是美国微软公司生产的基于其Windows系统的软件开发工具。

它具有使用灵活，并与32位Windows内核〔使用于Windows 2000/Windows XP〕高度兼容的特点，从而被Windows程序员们广泛使用。

VC 在图形图像处理方面有着广泛的应用，MFC中提供了大量的图形图像函数，下面我们将对使用VC/MFC编写简单的绘图程序。

一、使用VC编写MFC单文档应用程序很简单，只需要按照下面几个步骤进行：1.翻开MSVC集成开发环境。

双击桌面或“开始〞菜单中的Microsoft VisualC++6.0，不久将看到VC的编辑窗口，如图3-5：图1 VC启动界面2.选择菜单“File | New〞,在弹出的对话框中1)单击上方的选项卡“Project〞，2)选择“MFC AppWizard(exe)〞，3)在“Project name〞一栏中填写工程名，例如draw，4)在“Location〞一栏中填写你想把文件存放的位置〔目录〕。

然后按“OK〞。

见图2。

注意：第4〕步中指定你自己的目录，不要使用系统的缺省目录或者随便放在根目录或者其他的目录下。

这样便于你找到自己编写的程序。

图2 应用程序向导主界面3.在MFC Appwizard-Step 1中选择“Single Document〞，即单文档应用程序，点击“Finish〞，如图3所示。

注意：对于下面的操作我们可以忽略，直接点Finish即可。

图3 应用程序向导中选择单文档视图4.系统弹出一个当前工程信息的对话框，如图4所示，直接点“OK〞即可。

图4 新建工程信息5.进入程序编写的主界面，屏幕左下方为工作区，如图5所示，工作区中共有三种视图，分别是：1)文件视图〔“FileView〞〕,主要包括头文件，cpp文件以及资源文件。

我们在头文件中一般添加类的定义，类的成员变量和函数的声明，而在cpp文件中具体实现函数。

C#简单画图程序

C#简单画图程序实现过程：（1）新建窗体应⽤程序（2）添加⼀个MenuScrip控件；添加⼀个ToolScrip控件。

在ToolScrip控件中对每个单元，要将DisplayStyle属性改为Text（3）程序代码。

1、新建菜单事件主要⽤⽩⾊清除窗体的背景，从⽽实现“⽂件新建”功能[csharp] view plain copyprivate void 新建ToolStripMenuItem_Click(object sender, EventArgs e){Graphics g = this.CreateGraphics();g.Clear(backColor);toolStrip1.Enabled = true;//创建⼀个BitmaptheImage = new Bitmap(this.ClientRectangle.Width, this.ClientRectangle.Height);editFileName = "新建⽂件";//修改窗⼝标题this.Text = "MyDraw\t" + editFileName;ig = Graphics.FromImage(theImage);ig.Clear(backColor);} 2、打开事件⽤于打开“打开⽂件”对话框，并选择相应的图⽚，将图⽚绘制到窗体上. [csharp] view plain copyprivate void 打开ToolStripMenuItem_Click(object sender, EventArgs e){openFileDialog1.Multiselect = false;if (openFileDialog1.ShowDialog() == DialogResult.OK){//修改窗⼝标题this.Text = "MyDraw\t" + openFileDialog1.FileName;editFileName = openFileDialog1.FileName;theImage = Image.FromFile(openFileDialog1.FileName);Graphics g = this.CreateGraphics();g.DrawImage(theImage, this.ClientRectangle);ig = Graphics.FromImage(theImage);ig.DrawImage(theImage, this.ClientRectangle);//ToolBar可以使⽤了toolStrip1.Enabled = true;}} （3）保存菜单项的Click事件⽤于将窗体背景保存为BMP格式的图⽚[csharp] view plain copyprivate void 保存ToolStripMenuItem_Click(object sender, EventArgs e){saveFileDialog1.Filter = "图像(*.bmp)|*.bmp";saveFileDialog1.FileName = editFileName;if (saveFileDialog1.ShowDialog() == DialogResult.OK){theImage.Save(saveFileDialog1.FileName, ImageFormat.Bmp);this.Text = "MyDraw\t" + saveFileDialog1.FileName;editFileName = saveFileDialog1.FileName;}} （4）在Paint事件中将Image中保存的图像，绘制出来[csharp] view plain copyprivate void Form1_Paint(object sender, PaintEventArgs e){//将Image中保存的图像，绘制出来Graphics g = this.CreateGraphics();if (theImage != null){g.Clear(Color.White);g.DrawImage(theImage, this.ClientRectangle);}}（5）添加Frm_Text.cs⽂字输⼊框。

c语言opengl代码

c语言opengl代码使用C语言编写OpenGL代码OpenGL是一种跨平台的图形库，可以用于创建2D和3D图形。

它是一种开放源代码的库，可以在多种操作系统上使用，包括Windows、Linux和Mac OS X等。

在本文中，我们将介绍如何使用C语言编写OpenGL代码。

我们需要安装OpenGL库。

在Windows上，我们可以使用Mingw-w64或Visual Studio等编译器来安装OpenGL库。

在Linux上，我们可以使用GCC编译器来安装OpenGL库。

在Mac OS X上，我们可以使用Xcode编译器来安装OpenGL库。

一旦我们安装了OpenGL库，我们就可以开始编写OpenGL代码了。

下面是一个简单的OpenGL程序，它创建了一个窗口，并在窗口中绘制了一个三角形。

```c#include <GL/glut.h>void display(){glClear(GL_COLOR_BUFFER_BIT);glBegin(GL_TRIANGLES);glColor3f(1.0, 0.0, 0.0);glVertex2f(-0.5, -0.5);glColor3f(0.0, 1.0, 0.0);glVertex2f(0.5, -0.5);glColor3f(0.0, 0.0, 1.0);glVertex2f(0.0, 0.5);glEnd();glFlush();}int main(int argc, char** argv){glutInit(&argc, argv);glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB); glutInitWindowSize(500, 500);glutCreateWindow("OpenGL Window");glutDisplayFunc(display);glutMainLoop();return 0;}```在这个程序中，我们使用了GLUT库来创建窗口和处理事件。

用C语言实现画图程序

一、选题背景：画图程序，通过画图中的功能绘制出美丽的图案。

二、设计思想：利用数学三角函数制作山峰和花朵出一条曲线、用画圆函数绘制太阳的形状、再进行颜色填充用绘制直线的函数来绘制比较粗的光线、用矩形函数画出矩形的边框、再画地球、直线画赤道、弧线画南北极和钟表的刻度盘。
