一、操作系接
口渲染流程
下面是一个osg，创建窗口是示例代码：
/**运用OSG 创建窗口
**/#include <windows.h>
#include <iostream>#include <osgViewer/Viewer>
#include <osgViewer/api/Win32/GraphicsWindowWin32>
#include <osg/GraphicsContext>int main()
{// osgViewer::Viewer, 必须定义，前期准备均在其构造中完成osgViewer::Viewer vierer;// 窗口信息类osg::ref_ptr<osg::GraphicsContext::Traits> traits = new osg::GraphicsContext::Traits;traits->x = 100;traits->y = 100;traits->width = 800;traits->height = 800;traits->windowDecoration = true;traits->doubleBuffer = true;traits->sharedContext = 0;osgViewer::GraphicsWindowWin32* gw = dynamic_cast<osgViewer::GraphicsWindowWin32*>(osg::GraphicsContext::createGraphicsContext(traits.get()));if (gw != nullptr){gw->realizeImplementation(); // 创建窗口int a;std::cin >> a;}else {std::cout << "gw is null" << std::endl;}return 0;
}运行结果：
