OpenGL安装（适用于VS2017）

OpenGL安装（适用于VS2017）

这个是参考网上的博客，感谢前人的贡献，文末加上了一些我个人踩的坑

利用VS2017下的包管理软件Nuget下载安装OpenGL库
优点：安装很简单
缺点：每次创建项目都要重新下载OpenGL库

1. VS2017创建C++控制台程序，最好选择空项目（否则可能会有其他的错误）
   

2. 创建好了项目，点击菜单栏的“项目”下的“管理Nuget程序包”
   

3. “浏览”下输入NupenGL,两个都点击安装
   

4. 新建一个C++文件
   

5. 输入下面的Demo,运行F5

#include   
#include   
#include   
#include

void display(void) {
	GLubyte fly[] = {
		0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,

	};

	GLubyte halftone[] = {
		0xAA,0xAA,0xAA,0xAA,0x55,0x55,0x55,0x55,
		0xAA,0xAA,0xAA,0xAA,0x55,0x55,0x55,0x55,
		0xAA,0xAA,0xAA,0xAA,0x55,0x55,0x55,0x55,
		0xAA,0xAA,0xAA,0xAA,0x55,0x55,0x55,0x55,
		0xAA,0xAA,0xAA,0xAA,0x55,0x55,0x55,0x55,
		0xAA,0xAA,0xAA,0xAA,0x55,0x55,0x55,0x55,

	};

	glClear(GL_COLOR_BUFFER_BIT);
	glColor3f(1.0, 1.0, 1.0);
	glRectf(25.0, 25.0, 125.0, 125.0);
	glEnable(GL_POLYGON_STIPPLE);
	glPolygonStipple(fly);
	glRectf(125.0, 25.0, 225.0, 125.0);
	glPolygonStipple(halftone);
	glRectf(225.0, 25.0, 325.0, 125.0);
	glDisable(GL_POLYGON_STIPPLE);
	glFlush();
}

void init(void) {
	glClearColor(0.0, 0.0, 0.0, 0.0);
	glShadeModel(GL_FLAT);
}

void reshape(int w, int h) {
	glViewport(0, 0, (GLsizei)w, (GLsizei)h);
	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
	gluOrtho2D(0.0, (GLdouble)w, 0.0, (GLdouble)h);
}

int main(int argc, char** argv) {
	glutInit(&argc, argv);
	glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
	glutInitWindowSize(350, 150);
	glutCreateWindow(argv[0]);
	init();
	glutDisplayFunc(display);
	glutReshapeFunc(reshape);
	glutMainLoop();
	return 0;
}

效果图如下

可能遇到的小问题

1. 创建项目时windows控制台项目，而非空项目可能遇到如下问题

错误	C1010	在查找预编译头时遇到意外的文件结尾。
是否忘记了向源中添加“#include "pch.h"

最简单的解决方案就是重新创建一个空项目
2. 在C++一个项目只能存在一个.cpp文件，否则可能会报错
解决办法：在VS2017项目管理中找到要移除C++文件，右击移除即可
